I-25 lane extension work to start in September


The start date for the Interstate 25 North Managed Lane Extension project has moved up.

Brook Svoboda, Northglenn’s director of planning and development, told City Council during its July 22 regular meeting that work on the project would begin in September.

“What’s significant about this is that … it was our understanding that they weren’t going to be mobilizing until next spring at the earliest, they have accelerated that schedule with the an expectation to complete in 2015,” he said.

He added that in 15 years working with the Colorado Department of Transportation, he has never seen a project of that scale move as quickly and efficiently. He said if CDOT kept up its efforts, it would probably reach its 2015 completion goal.

The project, expected to be completed by summer 2015, calls for the construction of one new managed lane in each direction on I-25 between U.S. 36 and 120th by narrowing the inside shoulder of the existing thoroughfare.

This six-mile stretch of highway would then be repaved and installed with a new one-mile noise wall to accompany an existing three-mile noise wall.

Public transit and high occupancy vehicles with two or more passengers will be allowed free access to the continuous managed lanes, while all other vehicles will be assessed a toll.

The $44 million project is subsidized with a mixture of federal funds and local contributions from seven surrounding municipalities, including Adams, Broomfield and Weld counties along with the cities of Federal Heights, Northglenn, Thornton and Westminster. Thornton’s commitment was $1.75 million and Northglenn’s was $550,000.

In all, $34 million of the project will be funded through the state grants from the Funding Advancements for Surface Transportation and Economic Recovery (FASTER) program and federal grants through the Transportation Investment Generating Economic Recovery (TIGER) program. Apart from the $4,525,000 contributed by surrounding cities and counties, the remaining $5.8 million balance will be funded by Denver Regional Council of Governments federal funds and RTD local transit funds.
