The Montana Department of Transportation (MDT) and Riverside Contracting Inc. will be conducting milling and paving operations on US Highway 93 (US 93) from the intersection with Round Butte Road north to the intersection with 3rd Avenue and Old US 93.
All work is dependent on weather and other unforeseen factors.
Crews will be onsite Monday, April 22, through Friday, April 26, from 7 a.m. to 5 p.m. until paving is complete.
Traffic will be reduced to one lane in each direction where work is underway. Please follow all traffic control and watch for workers and equipment.
These additional milling and paving operations are required because the top layer of asphalt applied in one section of the project last fall failed to meet MDT’s standards. MDT is continually testing the materials used on Montana’s roadways to ensure they are the highest quality, will withstand our harsh climate, and provide a smooth driving surface for decades to come. If a material fails to meet MDT’s standards, it is removed, and new material is installed. This occurred only in one section. While we understand this causes more disruptions, it is critical that we keep Montana moving forward by using only the very best materials that will last for years to come.
Other activities to be completed this construction season include paving the shared-use path along US 93, painting the final epoxy road markings, and other finishing work. These activities will be off of US 93 and are not anticipated to impact traffic.
Streetlights and the new traffic signal at the US 93 intersection with Old US 93 and 3rd Avenue will also be installed. The installation of the traffic signal has been delayed due to unforeseen supplier issues. MDT is working to ensure the traffic signal is installed as soon as possible.
The Round Butte Road Path - Ronan project will also be completed. This project includes building two new sections of sidewalk on the north side of Round Butte Road. This schedule is subject to change due to weather and other unforeseen factors.
