CDOT ready to roll on $390 million in road projects in metro Denver area

By Kevin Flynn
Inside-Lane.com

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.

The activity is spread across 32 projects in the Colorado Department of Transportation’s Region 6, which covers much of the Denver area with the exception of Boulder and Douglas County south of Highlands Ranch. It includes projects CDOT is doing plus several city projects in Denver and Aurora on state highways that CDOT is overseeing.

CDOT’s Region 6 staff led by Region Director Reza Akhavan outlined the projects in a briefing that brought to light some of the savings achieved recently in bidding results that allowed budgeted funds to be plowed back into additional work.

“This will be keeping us very busy this year,” Akhavan said.

Foremost was savings in the $23.3 million 120th Avenue Connection project in Broomfield, which is providing a straight-across link west-to-east from CO 128 to 120th Avenue to allow traffic to bypass the busy Wadsworth/Midway Boulevard interchange with U.S. 36. Inside Lane wrote about this project when ground was broken, and at the time, CDOT didn’t have funding to start the second phase that would include the tie-ins on the east side with 120th.

Now, says CDOT Region 6 North Program Engineer John Schwab, savings achieved through the design-build contracting process used by CDOT and the contractor partnership of Edward Kraemer & Sons and HNTB will allow CDOT to begin design work on that second phase, as well as right-of-way acquisition. The hefty construction costs for that phase, estimated up to $40 million, means the rest will have to wait for more funding.

They projects range from the inexpensive– such as a $180,000 paint restriping of Parker Road between Hampden and Belleview Avenues to fit in third lanes in each direction, a small price to squeeze out extra traffic capacity on the busy corridor, and $500,000 for a wildlife fence along U.S. 6 between Heritage Road and 19th Street in Golden – to several in the $30 million and $40 million class.

Because of the lead time to get stimulus-funded projects underway, there are many projects this construction season that are being funded by the American Recovery and Reinvestment Act. They include the $47.2 construction of a new Central Park Boulevard interchange on Interstate 70 by SEMA Construction to provide better access to Denver’s Stapleton neighborhood and commercial area, the $17.9 million addition of a 17th Avenue interchange on Interstate 225 by Hamon Contractors to ease traffic flows into the Fitzsimons medical campus in Aurora, the $36.9 million replacement of the Alameda bridge over I-25 in Denver by Jalisco International and a new $32 million flyover ramp for southbound Santa Fe Drive to eastbound C-470 by Edward Kraemer and Sons in Littleton.

CDOT also will be starting up projects funded by the new revenue from the FASTER program’s vehicle registration fee hikes. They include new signals, auxiliary lane and realignment of the roadway geometry at the hazardous intersection of CO 7 and York Street in Adams County, more median cable guards on C-470 to prevent crossover head-on crashes and concrete median barrier on South Santa Fe Drive in Littleton.

“While a few large Recovery Act projects are still underway, there are many projects that are just starting that will greatly improve safety and mobility on our highway system,” said CDOT Executive Director Russell George. “Specifically, there will be several critical bridge and safety projects as a result of FASTER.”

Use this map of CDOT’s Region 6 — most of the Denver Metro area — along with the project descriptions below to see where these projects are located. I have put all 32 projects below with details on cost, schedule, work hours and project scope, along with pictures from many of them:

North Area (North Program Engineer John Schwab)
———————————————————

1. 120th Avenue Connection

Cost: $23.3 million

Contractor: Edward Kraemer and Sons, Inc.

Resident Engineer: Yet to be determined

Work: Constructs a new six-lane road across US 36 to connect 120th Avenue and State Highway 128 in Broomfield in order to provide greater connectivity to US 36 and local roadways. This project will construct two of the three phases needed to complete the entire project. As part of this project, a new bridge over US 36 will be constructed as well as a new bridge over Commerce Street. Several local roads such as Commerce Street, Old Wadsworth Boulevard and 118th Avenue will be realigned to correspond with the new roadway. The RTD park-n-Ride facility at Wadsworth Parkway will be relocated near the Broomfield Event Center. Currently, motorists in the Broomfield area can only cross US 36 at Wadsworth Parkway. Due to the lack of continuity with State Highway 128 and 120th Avenue, the US 36/Wadsworth Parkway interchange is heavily congested and State Highway 128 and 120th Avenue are operating at capacity during peak hours. Traffic forecasts indicate at least a doubling in traffic over the next 20 years. The new 120th Avenue Connection will provide relief on these major corridors by improving connectivity, safety and mobility.

Update: To date, crews have conducted embankment work on 120th Avenue and have begun bridge construction over US 36. Girders and bridge deck panels have been installed for the new bridge over US 36.

Work Hours: Single lane closures Sunday through Thursday from 8 p.m. to 5:30 a.m. with double lane closures from 10 p.m. to 5:30 a.m.

Work Hours:
I-25: Single lane closures Sunday through Thursday from 8 p.m. to 5:30 a.m. with double lane closures from 10 p.m. to 5:30 a.m. There will be occasional full closures of I-25 for girder installation, deck panel installation and bridge deck concrete pours.

When complete, the bridge will be wider to accommodate an additional left turn lane from 80th Avenue to Oakwood Drive and a wider sidewalk. The project also realigns 80th Avenue to the east to improve sight distance, access and traffic flow. The improvements will accommodate the future widening of US 36 as determined through the US 36 Environmental Impact Statement.
