The Montana Department of Transportation (MDT) has initiated the design for the reconstruction of US Highway 212 from Rockvale to south of Laurel. The project will follow the preferred alignment as presented in the Record of Decision for the Final Environmental Impact Statement for Rockvale to Laurel, completed in September 2009.
This project will reconstruct approximately 10.8 miles of US Highway 212 on a new alignment beginning at milepost 42.1 near Rockvale and continue northeast to milepost 52.7, south of Laurel. This project will be designed and constructed in multiple phases.
Four individual projects have been identified to facilitate design and construction of improvements along this corridor in phases. The projects are identified below along with the anticipated year when construction is expected to commence. All schedules are tentative and dependant on the completion of all project development activities and the availability of funding.
South of Laurel - RR Overpass; Construction 2013;
This project consists of the replacement of the railroad underpass and full reconstruction of the existing substandard two-lane roadway alignment at the northern end of the project corridor. The underpass will be replaced with a new grade-separated overpass of the BNSF Railway (BNSF) on a new alignment and include a new two-lane roadway connection back to the existing US 212 alignment approximately one-mile further south. The new roadway will consist of a four-lane roadway with depressed median.
Rockvale - North (US 212/310); Construction 2014;
This project consists of intersection and roadway improvements for the intersection of US 212 and US 310 at Rockvale. This project includes roadway reconstruction, overhead lighting, turn lanes, and replacement of the flashing beacon. The project will extend approximately 1.3 miles northeasterly of the intersection where it will connect with the existing US 212/310 alignment.
Rockvale - Laurel (2 Lanes); Construction 2015;
This project will construct a two-lane roadway, with intermittent four-lane segments, between the limits of the Rockvale - North (US 212/310) project and the South of Laurel - RR Overpass project. The project will also construct the earthwork and drainage features for the ultimate roadway template (four lane divided roadway with depressed median). The length of this project is approximately 10 miles.
Rockvale - Laurel (NB Lanes); Construction 2016 or beyond;
This project represents the construction of the remaining portions of the full build-out 4-lane sections. The overall project limits will correspond with the limits of the Rockvale - Laurel (2 Lanes) project identified above.
