VMT Fee Should Replace Gas Tax, ULI Report Suggests

Congress should consider initiating a vehicle miles traveled fee to replace the gasoline tax currently funding federal highway and transit programs, an infrastructure report issued by the Urban Land Institute and Ernst & Young recommends. The report also calls for boosting transportation investment through other sources.

This report is the fourth in an annual series. (Inside Lane note: Read and download the report here.) It focuses on the pressing need for long-term and integrated investments in transportation and other infrastructure.

“Investing in infrastructure — done well and strategically — can help ensure increasing prosperity and the rising standards of living that Americans have come to expect,” the report contends. “Many countries around the world — China, India, and those in Europe — understand the infrastructure investment imperative and are working to build the transportation, water, and energy systems that will grow their economies for future generations.”

There have been a few hopeful steps towards an adequately funded transportation system nationwide, the report notes. It highlights several transportation and finance programs in the American Recovery and Reinvestment Act such as those for high-speed rail, discretionary multimodal grants, and Build America Bonds.

The document includes examples of a few transportation-oriented public/private partnerships currently underway in the United States, and notes how these can offer “guideposts” for similar efforts elsewhere. These examples include the Florida Department of Transportation’s agreements for constructing a $2 billion tolled expressway expansion along Interstate 595 and a $1 billion tunnel for the Port of Miami, and the collaboration between the Texas Department of Transportation and a private operator for building High Occupancy/Toll lanes as part of a $4 billion widening and upgrade for Interstate 635.

One means of further encouraging those partnerships, the report suggests, is a national infrastructure bank based on Europe’s model for financing and attracting private capital. “A federal infrastructure bank could help establish procurement protocols and standards, facilitating the bidding process,” the report states.

The 102-page report, “Infrastructure 2010: An Investment Imperative,” is available at the Urban Land Institute website.

Bridge Demolition to Close I-25 Near 104TH Avenue Next Week

ADAMS COUNTY – The Colorado Department of Transportation (CDOT) recently completed the center portion of the new 104th Avenue bridge over I-25. With two thirds of the new bridge complete, crews will be realigning eastbound 104th Avenue onto the new bridge this week and demolishing the final third of the existing bridge.

“We have now completed two thirds of the new structure and will be removing all traffic from the old bridge this week,” said CDOT Program Engineer John Schwab. “With traffic realigned to the new structure, we can demolish and replace the southern portion of the bridge.”

As a result of the upcoming bridge demolition, there will be various lane closures on 104th Avenue as well as I-25 next week. The following closures will take place Sunday, April 18th through Thursday, April 22nd, weather permitting:
• Sunday, April 18th: All left turn movements from northbound and southbound I-25 to 104th Avenue and from eastbound and westbound 104th Avenue to I-25 will be prohibited from 12 a.m. until 5 p.m. on Sunday for paving.
• Monday, April 19th: A single lane of southbound I-25 at 104th Avenue will be closed at 7 p.m. followed by a full closure from 9 p.m. to 1 a.m. In addition, all lanes of northbound I-25 at 104th Avenue will be closed from 1 a.m. to 5:30 a.m. on Tuesday morning. Crews will be removing a fence on the 104th Avenue bridge over I-25. Detour: Motorists will be detoured via the on and off ramps at 104th Avenue. Uniformed traffic control will be used to direct motorists through the interchange.
• Tuesday, April 20th: The left lane and left turn lane to I-25 will be closed on eastbound and westbound 104th Avenue from 8:30 p.m. to 5:30 a.m. to allow crews to realign eastbound 104th Avenue onto the new bridge.
• Wednesday, April 21st and Thursday, April 22nd: One lane of northbound and southbound I-25 at 104th Avenue will be closed at 7 p.m. with all lanes closing at 9 p.m. for bridge demolition. All lanes will reopen by 5:30 a.m. the following day. Detour: Motorists will be detoured via the on and off ramps at 104th Avenue. Uniformed traffic control will be used to direct motorists through the interchange.

Major delays are throughout the week and alternate routes are strongly advised. CDOT would like to remind motorists to obey all traffic signs and flaggers and to “Slow for the Cone Zone.”

The existing 104th Avenue bridge over I-25 was originally constructed in 1962 and is one of Colorado’s structurally deficient bridges. When complete, the new bridge will accommodate an additional left turn lane from eastbound 104th Avenue to northbound I-25.

Hamon Contractors, Inc. is the contractor for this $6.5 million project scheduled to be complete by the end of January 2011. CDOT is funding the bridge replacement and the Northglenn Urban Renewal Authority (NURA) is funding the aesthetic improvements which will include upgraded bridge rail and upgraded bridge lighting similar to the existing lighting on the 112th Avenue overpass bridge. Aesthetic improvements also include cornerstone monuments at the four ends of the bridge and “Northglenn” monument signage mounted to an upgraded retaining wall.

C-470 Concrete Repairs Complete, Resurfacing Begins

DOUGLAS/JEFFERSON COUNTY— Crews have completed all of the concrete repairs on eastbound and westbound C-470 between I-25 and Santa Fe Drive and asphalt resurfacing is just beginning. Since temperatures are not yet warm enough for paving during the overnight hours, crews will continue to work on weekends.

“With the concrete work complete, we will micro-surface C-470, which seals the concrete and levels the pavement,” said CDOT Project Engineer Doug Liane. “Once that work is complete, we will resurface both directions of C-470 in asphalt for a smooth driving surface.”

This weekend, crews will work from 6 a.m. to 6 p.m. on Saturday and Sunday, weather permitting. The following closures will be in place:
Closures on Saturday, April 17, 2010
• Westbound C-470 between University Boulevard and Santa Fe Drive: The left lane of westbound C-470 will be closed from 6 a.m. to 6 p.m. on Saturday. Major delays are expected and alternate routes are strongly advised.
• Eastbound C-470 between University Boulevard and Yosemite Street: One lane of eastbound C-470 will be closed from 6 a.m. to 6 p.m. on Saturday. Major delays are expected and alternate routes are strongly advised.
• Lucent Boulevard to Westbound C-470: The ramp from Lucent Boulevard to westbound C-470 will be completely closed from 6 a.m. to 6 p.m. on Saturday. Detour: Motorists can take County Line Road to Santa Fe Drive where access to westbound C-470 is available.
• Westbound C-470 to Lucent Boulevard: The ramp from westbound C-470 to Lucent Boulevard will be completely closed from 6 a.m. to 6 p.m. on Saturday. Detour: Motorists can take Santa Fe Drive to County Line Road where access to Lucent Boulevard is available.
• Quebec Street to Eastbound C-470: The ramp from Quebec Street to eastbound C-470 will be completely closed from 7 a.m. to noon on Saturday. Detour: Motorists can take County Line Road to Yosemite Street or I-25.

Closures on Sunday, April 18, 2010
• Westbound C-470 between University Boulevard and Santa Fe Drive: The right lane of westbound C-470 will be closed from 6 a.m. to 6 p.m. on Sunday. Major delays are expected and alternate routes are strongly advised.
• Westbound C-470 to Santa Fe Drive: The ramp from westbound C-470 to Santa Fe Drive will be completely closed from 6 a.m. to 6 p.m. on Sunday. Detour: Motorists can take Platte Canyon Road to Mineral Avenue where access to Santa Fe Drive is available.
• Eastbound and Westbound C-470 at University Boulevard: The left lane of eastbound and westbound C-470 at University will be closed Sunday from 8 p.m. to 5:30 a.m.

In addition to the weekend work, the following lane closures will be in place Monday, April 19th through Friday, April 23rd, weather permitting:
• Eastbound and Westbound C-470 at University Boulevard: The left lane of eastbound and westbound C-470 at University Boulevard will be closed Monday from 8 p.m. to 5:30 a.m.
• Eastbound and Westbound C-470 at Broadway: The left lane of eastbound and westbound C-470 at Broadway will be closed Tuesday and Wednesday from 8 p.m. to 5:30 a.m.
• Eastbound and Westbound C-470 at Santa Fe Drive: The left lane of eastbound and westbound C-470 at Santa Fe Drive will be closed on Thursday from 8 p.m. to 5:30 a.m.

Delays are expected during work hours and alternate routes are strongly advised. CDOT would like to remind motorists to obey all traffic signs and flaggers and to “Slow for the Cone Zone.” Most fines will be doubled if the infraction occurs in the work zone.

This work is part of an American Recovery and Reinvestment Act (ARRA) project. The $32 million project will repair concrete along nine miles of C-470 and then pave the entire length in asphalt. Concrete repairs will also be made along 26 miles of the C-470 bike path between I-25 and I-70.

Castle Rock Construction Co. of Centennial, CO is the contractor for this project, which is scheduled to be complete by the end of September 2010.

In all, Colorado will receive more than $400 million from the Recovery Act for highway projects and $103 million for transit projects.

Save the last dance for me!

Denver, the city that popularized the pedestrian-friendly all-walk diagonal-crossing Barnes Dance, is considering phasing it out of the busy downtown grid as part of a larger evaluation of signal timing within the central business district.

Another Denver institution on the ropes? Could they leave the Barnes Dance, the cheeseburger and the ice cream soda in their native town and instead eliminate the Denver Boot?

“We have preliminary data from our consultant and we’re talking to stakeholders,” said Matt Wager, director of operations for traffic engineering services at Denver Public Works. “It’s a complex discussion.”

Pedestrians would still get “Walk” signals, but not the all-red diagonal crossing.

Wager said a decision is likely six months out. The “All Pedestrian Phase Study” is being done by Jacobs Engineering, while a larger retiming study of the downtown signal system, called the Downtown Denver Traffic Signal Retiming Study, is being done by Navjoy Consulting Services.
“We are taking a look at signal timing downtown and are evaluating not only pedestrians but bicycles, autos and transit,” Wager said. “We’re always evaluating signal timing downtown.”

In part, the retiming study is a response to RTD’s anticipated introduction of four-car light rail trains along Stout and California streets. The longer train consists – RTD now operates two- and three-car consists on the Central Corridor downtown – will require more all-red clearance at cross streets.

The so-called Barnes Dance refers to the inclusion of an all-red phase within the traffic signal cycle that stops vehicles on all approaches and allows pedestrians to freely cross, including diagonally. It’s called the Barnes Dance because it was brought to Denver by the city’s visionary first traffic engineer, Henry Barnes. He did not come up with it, but was the first to apply it in an entire downtown zone when it went live in 1952.

In his autobiography, “The Man with the Red and Green Eyes,” Barnes said he came up with the notion for the all-walk phase while dropping his daughter off at school and watching her try to cross the street with her friends. People trying to cross the street during breaks in traffic were playing games of chicken. In a presentation in Los Angeles to a meeting of the Institute of Traffic Engineers, Barnes told them:

“As things stood now, a downtown shopper needed a four-leaf clover, a voodoo charm, and a St. Christopher’s medal to make it in one piece from one curbstone to the other. As far as I was concerned – a traffic engineer with Methodist leanings – I didn’t think that the Almighty should be bothered with problems which we, ourselves, were capable of solving. Therefore, I was going to aid and abet prayers and benedictions with a practical scheme: Henceforth, the pedestrian – as far as Denver was concerned – was going to be blessed with a complete interval in the traffic signal cycle all his own. First of all, there would be the usual red and green signals for vehicular traffic. Let the cars have their way, moving straight through or making right turns. Then a red light for all vehicles while the pedestrians were given their own signal. In this interim, the street crossers could move directly or diagonally to their objectives, having free access to all four corners while all cars waited for a change of lights.”

Barnes acknowledged there were such intersections already using such a signal by the 1940s in Kansas City, Vancouver and a few other places. But Denver was where Barnes had them installed throughout the business district, where for the most part they remain in use today.

But downtown Denver has changed.

The 1982 debut of the 16th Street Mall into the traffic flow presented signal timing issues. To accommodate the transit shuttles, 16th was converted to two-way traffic from its former one-way function in the downtown grid. Engineers had to integrate efficient timing for RTD’s shuttle business going in both directions into a total 75-second cycle from green to green. Also, since the original Denver grid is platted on a 45-degree diagonal to north-south-east-west, the connections to East Denver and Golden Triangle streets east of Broadway and south of Colfax Avenue present timing issues.

Wager said Denver uses the mall shuttle movement as the starting point for setting all the other timings.

The diagonal crossing was dubbed the “Barnes Dance” after Denver Post city hall reporter John Buchanan wrote that, despite citizen and official apprehension in advance of its introduction, the innovative all-walk phase had pedestrians “dancing in the street.”

Barnes also oversaw the demise of the Denver Tramway’s 1950 conversion of the city’s extensive but aging streetcar lines to buses – having been quoted as saying he had no objection to streetcars except that they ran in the street.

Barnes departed Denver a year after introducing his dance and became traffic engineer in Baltimore, where he introduced computerized signal controls. He was hired to be New York City’s traffic commissioner in 1962 by Mayor Robert Wagner. Barnes used the all-walk phase in Manhattan, although only a few locations remain in use today.

He died of a heart attack on the job in New York in 1968, at the age of 61.

On a personal note, my own subconscious awareness of the Barnes Dance and downtown signal timing nearly got me whacked by a car when Denver altered signal timing with little fanfare years ago. While working at the Rocky Mountain News, I was in the habit of taking reading material with me when walking to appointments or lunch. The timing patterns had been inculcated into my brain for years: Named streets got the green light first, then the numbered streets, followed by the all-walk Barnes Dance.

One day, walking back to 400 W. Colfax from the Brown Palace, I stepped to the curb at Tremont Place and 17th Street, my nose in a book, looking to cross west toward 16th. When the last of the traffic zoomed past me on 17th, I started out into the street still reading, confident Henry Barnes had my back.

But I heard cars starting out from Tremont, including some making a left turn right into my path. I looked up to see a bumper coming at me, and jumped back.

I found out Denver traffic engineers had flipped the order of the signal phases east the mall. Numbered streets now went first, named streets second.

The oldest bridge on the FASTER list for replacement is the nearly 90-year-old cliff-hugging Million Dollar Highway bridge over Bear Creek Falls near Ouray. Inside Lane photo.

The Telluride Watch reports that drivers who regularly use Red Mountain Pass can expect major road construction starting this August when the Colorado Department of Transportation will begin a $5.7 million Bear Creek Bridge replacement project on U.S. Hwy. 550 south of Ouray.

Phase I of the project is expected to begin on Aug. 1 and end approximately Nov. 1, CDOT Region 5 Resident Engineer Ed Archuleta told the Ouray County Commissioners on Monday.

Go to the Telluride Watch to see the entire report.

The spending goes mainly to road, bridge work that bolsters trucking infrastructure. The latest figure, posted on the Recovery.gov site, is up from $10.264 billion as of March 26. DOT has made nearly $38 billion available to states for infrastructure projects under the 2009 American Recovery and Reinvestment Act, and issues payments once it confirms work has been done.

CO 96 wood timber bridge over draw in Kiowa County, 3.3 miles east of Crowley County line.

By Kevin Flynn
Inside-Lane.com

A total of $25.3 million in state highway projects funded by the FASTER program is in CDOT’s pipeline, including replacement of four wooden bridges along a state highway where volunteer firefighters died in 2008 crossing where a fifth wooden bridge had been destroyed in a wildfire.

The 10 separate projects include $8.2 million in bridge replacements and $17.1 million in road safety work.

The list includes those under contract, those with bids already taken and those currently out for bids.

FASTER, which stands for Funding Advancement for Surface Transportation and Economic Recovery, was passed by the legislature last year. It represents the first new local funding to come in to state transportation projects in 19 years, since the gas tax was last increased. Some of FASTER’s revenue is allocated to cities and counties for local roads.

FASTER established two separate fees, earmarked to road safety projects and to replacement of the 124 poor-rated bridges on the state highway network.

The annual road safety fee is a sliding scale based on vehicle weight. Ranging from $16 for light vehicles to $39 for vehicles over eight tons, the owner of the average passenger car between one and two and a half tons would pay $23.

The bridge fee is also a sliding scale based on weight, and is being phased in over three years. Currently at $9 for the average passenger car, it will be $18 in two more years.

As a result, the owner of an average passenger car would pay $41 in 2011-12 between the two fees.

Among the bridges being replaced this year are four wooden structures on CO 96 in Crowley and Kiowa counties in southeast Colorado. It was on this corridor that a fifth wooden bridge west of Ordway burned in the grassfires of April 2008, and a fire truck from the Olney Springs volunteers rushing to help protect Ordway plunged over the abutment and into the Numa Drain Canal. Two firefighters died in the crash. The structures had been built in the 1930s and 1940s.

Here is the list of FASTER projects currently in the process of contracting:

4th Street Bridge Advisory – Major Traffic Switch Friday Morning

April 14, 2010 – Southeastern Colorado/CDOT Region 2 – PUEBLO – The Colorado Department of Transportation (CDOT) is getting ready to move all traffic on the current 4th Street Bridge onto the new westbound structure by 7 a.m. on Friday, April 16.

Drivers should expect occasional traffic stops and delays up to 10 minutes through the area on Thursday as preparations are made for the realignment.

Traffic is being moved to allow the eastbound bridge to be demolished over the next four to six weeks. In addition:
• Eastbound and westbound traffic will remain in a single-lane configuration on the new bridge
• No left turns will be allowed at the Elmhurst Place/Pearl Street intersection while construction is taking place near the west end of the bridge
• Pedestrians access will be limited to the new, north sidewalk on 4th Street due to demolition of the old bridge
• Traffic will be traveling on an unfinished road surface and may experience bumps, which will be removed when final paving is completed later this year
• Shoulder closures will remain on the new westbound bridge, allowing access for eastbound bridge construction
• The loop ramp from eastbound 4th Street to Midtown Center will remain closed until bridge demolition is complete
•
In addition, CDOT has closed the Arkansas River Trail under the bridges to maintain safety for pedestrians and bicyclists. It is scheduled to reopen on June 1, 2010.

The new eastbound bridge is expected to open to traffic in its final configuration in December 2010. Landscaping and other finishing work will take place in spring 2011, with project completion scheduled for summer 2011.
