Project Overview

Current Project Status

Paving on this project is completed for the 2020 construction season and traffic is on 2-lanes (1 each direction) of paved surface for the length of the project. Paving for this project will resume in the spring of 2021 and the project will be completed in the 2021 construction season. There will be little to no work on this project through the winter months and no impact on traffic.

This project will bring this section of US 287 into compliance with current design standards and improve stopping and sight distance. Construction is expected to be completed over two seasons (2020-2021). Initial paving (25 percent completion) was completed in November of 2020, and remaining paving and final improvements will be completed in the summer of 2021.

Once completed, the highway will support two northbound lanes and two southbound lanes with an additional center turn lane at the junction with Secondary Highway 437 North towards Radersburg. Improvements will connect existing 4-lane sections between the I-90 Interchange and Toston in order to finalize roadway improvements in this area.

As always, pay attention, slow down and be careful as you pass through the work zone.
