Project Overview

Future I-25 Footprint

In October 2013, the Colorado Department of Transportation (CDOT) began a safety and mobility project on a 6-mile segment of I-25 between US 36 and 120th Avenue. The project will maximize the use of the existing highway infrastructure to expand the capacity of I-25 by adding one HOV/tolled Express Lane in each direction.  In addition, the project will resurface the existing lanes along this 6-mile stretch.

Progress

Construction is taking place on the northbound I-25 shoulder along the 3 miles between Thornton Parkway and 120th Avenue, and is on schedule. Work includes shoulder excavation and reconstruction to accommodate the new internal Express Lane; electrical installation at 120th Avenue, which is near completion; and guardrail placement. Overhead sign foundations also have been installed and asphalt will be placed in the coming month.

In addition to the shoulder reconstruction, work has begun on construction of two new 12-foot high, concrete sound barriers on the northbound side of I-25 near the US36 interchange. Sound barriers also are being constructed on the northbound side of I-25 just before 120th Avenue. On the southbound side of I-25, striping removal, restriping and a lane shift has occurred to accommodate for construction.

Profile lowering of I-25 at 88th Avenue to allow for improved vertical clearance is on pace to begin in June. Traffic impact will increase as patterns shift to accommodate construction in this phase of work. More information about a Telephone Town Hall meeting, which is scheduled for mid-May and will detail this aspect of the project, will follow in an update.

Project Schedule and Impacts

Normal working hours are Monday through Friday from 7 a.m. to 4:30 p.m. There will be some night operations through April for barrier placement and roadwork between Thornton Parkway and 120th Avenue.
