DOWL provided detailed design and prepared final construction documents for a Montana Department of Transportation project to reconstruct an 11-mile segment of US 212 between Rockvale and Laurel, Montana. The project consisted of development of a four-lane divided highway along a new alignment which would replace the existing two-lane facility. For constructability, the project was split into multiple phases that required a detailed evaluation of improvements within each phase. This included two-lane versus four-lane alternatives, truck climbing lanes, intersection locations, and turn lanes. DOWL provided considerable support for the right-of-way negotiation process and conducted additional landowner meetings, developing exhibits, and designing refinements. The project included design and legal surveys, aerial mapping/control survey, utility coordination, public involvement, roadway design, bridge design coordination, irrigation, drainage, lighting, signing, and pavement markings.
