Pre-construction activities continue on I-25/Cimarron Interchange Project with soil testing

May 28, 2015 - Southeastern Colorado/CDOT Region 2 - Colorado Springs – Beginning Sunday, May 31, weather and other conditions permitting, crews on the Colorado Department of Transportation’s (CDOT) Interstate-25/Cimarron Interchange Design-Build Project will begin testing soil project-wide.

This work may require short-term, intermittent, overnight shoulder and single lane closures throughout the project corridor from 9 p.m. to 6 a.m. for the next few weeks.

“This initial work will provide critical information to the contractor as they begin the design process for this project,” said Dave Watt, CDOT Project Director. “It’s exciting to see things getting started.”

While this initial soil testing will require some overnight shoulder and lane closures, the bulk of construction activity throughout the remainder of 2015 will take place offline. Roadwork is scheduled to begin in spring 2016.

Recently, crews began necessary removal of vegetation and invasive tree species (clearing) near the project area, in coordination with Colorado Parks and Wildlife. This work will continue for the next few weeks and is needed to facilitate Fountain Creek restoration, Midland Trail improvements and earthwork along the west side of I-25.

PROJECT INFORMATION: The $113 million I-25/Cimarron Interchange Design-Build Project involves rebuilding the I-25 interchange between Colorado Avenue on the north and South Nevada Avenue to the south, 8th Street on the west and the Cimarron Street bridge over Fountain Creek on the east. Improvements are intended to provide enhanced operations, correct existing safety and design deficiencies, and to serve the anticipated short- and long-term travel demands in this area.  When complete, this will be a high-functioning interchange that safely handles more vehicles and enhances multi-modal travel for those using I-25, US 24/Cimarron Street and the trail system along Monument and Fountain creeks. Substantial completion is planned for fall 2017.
