I-25 Southwest Frontage Road near Timnath closed for subsurface drainage installation October 3-21

As the Colorado Department of Transportation continues with I-25 widening and drainage improvements, crews will install an underground drainage line, culvert and entrance under the Southwest Frontage Road between Colorado Route 392 and the Kechter Road as part of the 100-year flood prevention portion of this project.

To safely place the new sub-drainage system, a complete closure of SW Frontage Road from north of CO 392 (the Colorado Mountain RV entrance) to south of County Road 34E will take place from 3-21 october.

When complete, the project will increase capacity on I-25 by adding a two-way expressway, constructing inner and outer shoulders, and replacing other aging bridges. The project will also improve multimodal access to regional transit along the corridor.


Complete SW Frontage Road closures from north of the Colorado Mountain RV entrance to south of County Road 34E will occur from 6:00 a.m., October 3, to 5:00 p.m., October 21. Access to local residences and businesses will be maintained. I-25 traffic will not be impacted when the drainage is installed.
