Where jetliners used to cross Interstate 70, Denver soon will be building a new $50.6 million interchange project that will reunite the south side of the old Stapleton airfield with the north side. But this time, it’s not 747s or DC-10s that will go over top of I-70 traffic, but Stapleton neighborhood residents, regional shoppers and other highway travelers.

It’s a first in the United States for bridge construction – the FasTracks bridge over Sixth Avenue Freeway in Lakewood will be rolled into place intact during a weekend highway closure in April.

RTD’s sales tax revenue for January retreated slightly after two months of gains, even as Colorado’s statewide sales tax collections for January retail sales went up two percent.

Flatiron Construction is the apparent low bidder for repairs to the Interstate 70 viaduct in Glenwood Canyon, which was heavily damaged in the Monday rockslide, the Colorado Department of Transportation announced. The contract is for $860,417, with Flatiron committing to completion in 55 days.

SEMA Construction again completed replacement of an aging steel truss bridge on U.S. 34 in Big Thompson Canyon four days ahead of schedule, reopening the major route between Estes Park and Loveland Thursday night – and completing the $3.8 million project.

Interstate 70 reopened to traffic around 3 p.m. Thursday for the first time in four days through Glenwood Canyon, with CDOT clearing one lane in each direction through the area damaged by a rockslide early Monday morning.

The dirt is starting to move in the $40.1 million design-build reconstruction of four miles along Hampden Avenue, starting at the east end of the corridor with replacement of the bridge over Federal Boulevard. Inside Lane takes you on a tour of the job with this video featuring the project managers, plus a slide show.

The FasTracks Northwest Rail corridor could get a head start under a plan that would build its first six and a half miles, between Denver Union Station and south Westminster at 72nd and Lowell Boulevard, as part of the construction of lines to the airport and Arvada. That will give RTD the capability of initiating rail transit service to southwest Adams County and Westminster sooner rather than later.

The Colorado Department of Transportation says it will reopen two lanes of Interstate 70 through the damaged rockslide area in Glenwood Canyon by the end of the day Thursday after geologists blasted down a huge boulder and surrounding rock that threatened to fall onto the highway.

CDOT says the current plan for closed I-70 through Glenwood Canyon is to repair a large hole in the eastbound structure, then reopen it to one lane in each direction. That would allow traffic to resume while repairs are made on the larger hole in the westbound structure.
