Travel Advisory

We appreciate the public’s patience as we enter another important phase of the project. If possible, alternative routes that avoid the project area are highly encouraged during this temporary traffic pattern.

Starting April 27 - Mineral Avenue Traffic Shift

Starting on Monday night, April 27 and lasting until further notice, both directions of traffic on Mineral Avenue from just west of the Santa Fe Drive (US Highway 85) intersection to west of Platte River Parkway will be shifted to the north side of the roadway into a two-way, single-lane alignment.

To accommodate this reduced alignment and keep east-west traffic flowing, the traffic signals at the Platte River Parkway and Mineral Avenue intersection will be removed, with north-south access limited to right turn lanes only to and from westbound Mineral Avenue. Detour routes will be posted to access eastbound Mineral Avenue via Aspen Grove and Santa Fe Drive.

This temporary traffic pattern will remain in place while crews widen the south portion of the roadway and make traffic signal and pedestrian improvements as part of the Santa Fe and Mineral Improvements project.
