Thank you for your patience as the North of Stevensville-North project moves forward. The Montana Department of Transportation (MDT) is currently working to complete hydraulic details for the project, finalize right-of-way agreements, and complete final roadway design plans, specifically the roundabout at Ambrose Creek Road.
A contractor will likely be selected in 2025, closer to the anticipated start of construction.
This project will reconstruct nearly six miles of Secondary Highway 203 (S 203), commonly known as Eastside Highway, enhancing roadway safety features and making the highway a more efficient travel experience. Proposed work includes 12-foot-wide travel lanes, a 12-foot-wide center left-turn lane, and four-foot-wide shoulders. Roadside slopes and ditches will be revised to improve safety and the vertical alignment and drainage features will be upgraded throughout the project. The existing 90-degree curves at Rathbun Lane and Ambrose Creek Road will be replaced with a large radius curve at Rathbun Lane and a four-legged roundabout at Ambrose Creek Road.
Project Overview
STPS 203-1(15)4
North of Stevensville - North
UPN 6138000
The project is located on Secondary-203 (Eastside Highway) and begins at Reference Post (RP) 4.0, about 3.7 miles north of Stevensville, and about 0.1 miles south of Wildfowl Lane and Moiese Lane. It extends northerly 5.8 miles to RP 10.1, about 0.2 miles south of Hidden Valley Road. This project will tie to the Florence – East project that was constructed in 2014.
The project will reconstruct the road to a 44-ft. top width that will provide two 12-foot travel lanes, a 12-foot center/left turn lane, and two 4-foot shoulders. Roadside slopes and ditches will be revised to improve safety and the vertical alignment and drainage features will be upgraded throughout the project. The existing 90° horizontal curves at Rathbun Lane and Ambrose Creek Road will be replaced with a large radius curve at Rathbun Lane, and a 4-legged roundabout at Ambrose Creek Road. A graded platform for a future shared use path will not be included.
The project will require extensive right-of-way acquisition and utility relocation.
