With warmer weather to help it along, construction progress on the West Corridor light rail project is ramping up on all three areas into which it’s been divided.

The work may be most visible along the Sixth Avenue Freeway, where a dramatic steel arch bridge will be rolled out over the roadway during a full weekend closure in two weeks and a long curving bridge is winding its way over the Indiana Street interchange. Denver Transit Construction Group and its major subcontractors have almost all of the bridge structures underway.

RTD’s West Corridor is the first new FasTracks rail corridor to go to full construction.

Reprinted below is a report on construction progress given to the RTD board by General Manager Phil Washington on April 2:

CONSTRUCTION UPDATE – AREA 1 (Jeffco Government Center to Federal Center)
• Work on walls and drainage continues near I-70.
• Light rail bridge construction (pouring piers, footing work, and deck pours) is taking place on both sides of Indiana Street at 6th Avenue. Crews have stripped the wood forms from the north side of the bridge to expose the concrete setting of the bridge and begin the post-tensioning process between two spans of the bridge. The wood forms have been placed on the south side to begin pouring there.
• Crews continue working on the bridge over Colfax, they anticipate pouring the deck of the bridge within the next two weeks.
• Ulysses Street in Golden is closed from 6th Avenue north to Mt. Vernon Road to raise the street and install retaining walls. Improvements to the Lena Gulch on Ulysses at 6th Avenue will be winding down soon. Retaining wall construction could begin within the next few weeks.
• Work at the Jefferson County Government Center including excavation and retaining wall construction has begun. The current bike path has been detoured down Johnson Road to Jefferson County Parkway.
• Wall construction on the south side of 6th Avenue west of Simms/Union is near completion. Excavation and wall construction on the north side of 6th Avenue from Indiana to Colfax is on-going.
• Crews will begin removing trees and vegetation from the northwest corner of the Cold Springs park-n-Ride in preparation for the Simms/Union light rail tunnel.

CONSTRUCTION UPDATE – AREA 2 (East of the Federal Center to Sheridan)
• Work continues on the Wadsworth Bridge, crews are working on the formwork for the deck of the bridge.
• The post-tensioning of the cables on the arch of the 6th Avenue Bridge has been completed. Crews are currently stripping the formwork on the south side of the bridge, with the rollout of the bridge scheduled for April 23-25.
• Work on a drainage culvert on Collins Avenue north of 6th Avenue and east of Simms is near completion.
• Work continues on a drainage system on 13th Avenue from Zephyr to Carr Street. Crews are paving 13th Avenue between Wadsworth and Allison this week, local access is allowed. Weather pending, Allison is scheduled to be open next week.
• The encasement of the Rocky Mountain Ditch on 13th Avenue between Carr and Cody is ongoing. During this work, 13th Avenue will be closed from Carr – Dudley, local access will be allowed. Upon completion, crews will begin working on additional drainage improvements from Cody – Holland. 13th Avenue will remain closed to through traffic for this operation.

• Relocation of utilities continues during the first phase of construction of the Federal Blvd. Bridge. Federal Boulevard has been phased down to two lanes in each direction, eliminating the left turn lane to Holden Place and left turns from Holden Place to Federal Boulevard. Traffic control is in place on Federal Boulevard between 10th Avenue- Howard Place. The pedestrian bridge over the gulch at Hazel Court is now open and the west side sidewalks of Federal have been closed down. Permanent fencing will be installed next week.
