The RTD FasTracks West Corridor team will roll out the main span of a double-track light rail bridge across 6th Avenue just east of Simms/Union the weekend of April 23rd through April 25th. All lanes of 6th Avenue between Simms/Union and Kipling Street will close at 8:00 p.m. on Friday, April 23rd to prepare the area for the roll-out, scheduled to begin early Saturday morning. 6th Avenue and the frontage road will re-open by 5:30 a.m. Monday, April 26th.

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. As a result of the upcoming bridge demolition, there will be various lane closures on 104th Avenue as well as I-25 next week.

WCAX TV in Burlington, Vt., reports that Flatiron Construction of Lafayette is the apparent low bidder to build the new Crown Point bridge across an arm of Lake Champlain to connect New York and Vermont.

The old bridge was brought down by controlled demolition in December after inspectors closed it due to its condition becoming unsafe.

Flatiron’s bid was around $69 million. There were nine bidders on the project, none from Vermont. Vermont Department of Transportation officials stressed this was an apparent low bidder but Flatiron will not be awarded the contract until the bid is fully vetted.

In a recent bridge inspection that took place earlier this week, Colorado Department of Transportation (CDOT) bridge engineers determined that portions of the northbound I-25 bridge deck over Santa Fe Drive need to be rehabilitated due to deteriorating concrete.

The repairs include removing the existing asphalt, removing the deteriorated concrete, replacing the bridge deck with new concrete, paving, and striping. The majority of the repairs will take place in the right lane of northbound I-25 with additional work taking place in the other lanes of northbound I-25 over Santa Fe Drive.

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.

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 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.

More than $390 million in road construction projects on state highways will be underway this year in the metro Denver area, with more than a third of the total funded by the federal stimulus program.

When FasTracks rolls out the bridge that will span West 6th Avenue on the west side of the Federal Center, it will do so literally, closing down a stretch of the heavily traveled highway for two days.
And the Regional Transportation District plans to make the snail’s pace placement of the bridge a spectator event.
