Rockvale to Laurel | US 212/310
Project Near Final Completion
The new US Hwy 212/310 between Rockvale and Laurel is open and is all four lanes. Minor work items are still yet to be completed. Expected the week of August 17th is the installation of permanent epoxy lane striping. Traffic will be able to move around the trucks as they paint but drivers should take caution near these slow-moving operations. No other traffic impacts are expected, and seeding won’t occur until the fall. Seeding will occur off the roadway with minimal impact to traffic.

The Montana Department of Transportation together with its construction contracting partners continue to take the COVID-19 pandemic very seriously. Construction projects on Montana's roads and bridges are considered an "essential" operation and will continue moving forward as scheduled in 2020. Construction workers will continue several measures to help keep employees, contractors and the public safe during the construction season. Some of the measures include following social distancing and good hygiene guidelines, and not reporting to work if showing symptoms of illness. For more information visit https://covid19.mt.gov/.
This project is construction of the remaining portions of US Highway 310 and US Highway 212 to achieve the full build-out of the planned four lanes. The continuing growth of traffic and safety conflicts between regional tourists, commuters, and truck traffic, as well as, the concerns voiced by local leaders prompted the completion of this roadway in 2020.

Phase 1 | Completed 2014
This phase actually abandoned a narrow, skewed underpass beneath the railroad and constructed two new bridges over the railroad, rather than replacing a skewed bridge crossing over the railroad tracks. The MDT Project name was South of Laurel-RR Overpass.
Phase 2 | Completed 2015
Included roadway reconstruction, overhead lighting, turn lanes, and replacement of the flashing beacon at the Rockvale North intersection of US 212 and US 310. The MDT Project name was Rockvale-North (US212/310).
Phase 3 | Completed 2019
In phase 3, MDT built a new roadway for 10 miles of U.S. 310 and U.S. 212 south of Laurel. Traffic was shifted onto the new 2-lane road, transitioning in several spots to 4 lane, mid-summer 2019. The new roadway left the river bottom area and shifted west onto the hills to minimize impacts to existing farms, homes, and communities.
Phase 4 | Completed 2020
This phase of the US 212/310 from Rockvale to Laurel project created four lanes for the full 10 mile stretch between the two communities.
