July 2026 - North of Stevensville - North, Eastside Highway Project Status Update
The Montana Department of Transportation (MDT) is continuing progress on the North of Stevensville – North, Eastside Highway project. Active roadwork is tentatively scheduled to begin this November, with minor operations. Utility work is ongoing.
A contractor will be selected in early fall. Once they are brought on board, a phasing plan and construction schedule will be determined and communicated to the public. Major active construction won't be underway until 2027.
The North of Stevensville – North project will reconstruct approximately 6 miles of roadway starting 300 ft south of Moiese Lane/Wildfowl Lane, and ending just north of Huckleberry Lane. Safety upgrades will include a rebuilt roadway with a center two-way left turn lane, wider shoulders, flatter roadside slopes, drainage improvements, a gentler curve at Rathbun Lane, a four-legged roundabout at Ambrose Creek Road, and upgraded pavement markings, signing, delineation, and rumble strips.
A nearby, separate project is taking place this summer called the Florence-East project. This pavement preservation project begins half a mile south of the 8 Mile Creek Road roundabout and ends at the intersection with US Highway 93 (US 93). Messaging boards and traffic signals are in place to direct traffic in this area. View more information on the Florence-East project.
More details will be shared as construction approaches in late 2026. In the meantime, community members can monitor statewide travel conditions and project impacts using MDT’s 511 map: https://www.511mt.net.

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.
