February 2023 Update
The Montana Department of Transportation (MDT) is continuing to prepare for the North of Stevensville-North project. The project team is currently working through right-of-way acquisition. A contractor will likely be selected in 2025, closer to the start of construction.
Thank you again to all virtual and in-person attendees at the September 2022 open house. If you missed the event, please feel welcome to view the recording of the virtual open house.
This project will reconstruct nearly six miles of Secondary 203 (Eastside Highway), enhancing 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 4-legged roundabout at Ambrose Creek Road.
MDT appreciates feedback and continued comments, questions, or concerns on this project and others in the area. Regular updates will continue as progress is made.

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.
