Project Update 01-21-2026

Travel Advisory & Project Update

Starting on Thursday, Jan. 22, 2026 and lasting until about 5 p.m. on Friday, Jan. 30, the City of Littleton and the Colorado Department of Transportation will close the far left turn lane from northbound Santa Fe Drive (US HIghway 85) to westbound Mineral Avenue and close the left lanes in both directions of Mineral Avenue within the project limits. These traffic impacts will remain in place during the nine-day period as part of the Santa Fe and Mineral Improvements project.

The closures are necessary so crews can remove portions of the existing median and begin widening and traffic signal improvements on the west side of the project corridor at the Platte River Parkway and Mineral intersection.

Other work underway sitewide includes backfilling and waterproofing the newly installed concrete box culvert in the southwest portion of the project, installing storm drainage pipe and inlets, potholing, and starting excavation for the new quad roadway.
