Sanderson Stewart out of Bozeman completed the engineering and design, and Riverside Construction out of Missoula and Billings has been awarded the construction contract. MDT updated the US 191 traffic signal in the 2021 season and Lone Mountain Land Company will complete the construction of a turn lane into the Powder Light Subdivision by late summer 2022. Utility relocations were also completed during the spring of 2022.
Depending upon weather conditions, construction is anticipated to be substantially completed during the 2023 season with chip sealing and final pavement markings completed in 2024.
In addition to roadway improvements, this grant will provide funding for the purchase of four motor coaches for Skyline Bus and six AWD vans for the Skyline vanpool program.
