Project Overview
Through the Timber Bridges – Glasgow Area project, the Montana Department of Transportation (MDT) and its partners, Sletten Construction and Morrison-Maierle, are working to replace up to 16 timber bridges within three years in northeastern Montana. Areas impacted include US Highway 2 (US 2) between Hinsdale and Glasgow, MT Highway 24 (MT 24) between Glasgow and Opheim, MT Highway 248 (MT 248) between Opheim and Scobey, and MT Highway 251 (MT 251) between Poplar and Flaxville.
The State’s aging timber bridges have a limited service-life remaining and replacing them is a top priority. These structures are vital to keeping Montanans connected and our economy moving forward. MDT is proactively investing in replacing this aging infrastructure through an innovative bridge bundling program. The Glasgow-area bridges are being replaced as a bundle through this program.
Utilizing a design-build contract, the consultant design firm, Morrison-Maierle, has been working alongside Sletten Construction from the start of the project, allowing the bundled projects to move more efficiently from design to construction-ready. This partnership has allowed the project team to develop better solutions, reduce project costs, and maintain quality while expediting project delivery.
Current Construction Activity:
The Montana Department of Transportation (MDT) and Sletten Construction replaced seven timber bridges in the Glasgow area during the 2023 construction season.
The seven bridges replaced are located on:
- Montana Highway 248 (MT 248), five miles east of Richland, seven miles east of Richland, two miles west of Scobey, three miles west of Scobey, and two miles west of Four Buttes.
- Montana Highway 251 (MT 251), 25 miles northeast of Poplar.
- US Highway 2 (US 2), 14 miles northwest of Glasgow.
In 2024, crews anticipate replacing up to eight timber bridges located on US 2, MT 248, MT 251, and Montana Highway 24 (MT 24). More location information is provided below. Depending on the area's requirements, the bridges will be replaced by either a concrete culvert or a concrete bridge.
Construction detours will be directly adjacent to the current structures, and minimal traffic disruptions are anticipated. Traffic control will be on-site, speed limits will be reduced, and shoulder closures will be in place throughout the construction zones. Brief, single-lane road closures may be periodically required.
