The Montana Department of Transportation may install a traffic light at the intersection of Broadway and Main streets in Belgrade â also known as the four-wayâ â before ground is broken for a railroad underpass at Main and Jackrabbit Lane. City officials and MDT officials met this week to discuss the status of the Belgrade Urban Project, for which the state Transportation Committee has authorized preliminary design work. The project, originally proposed to widen Jackrabbit Lane between Madison and Main from three to five lanes, has since grown in scope to include construction of a railroad underpass at Jackrabbit and Main. If the Transportation Committee votes in October to add the project to MDTâs five-year plan, ground could be broken on the project in 2026, state officials have said.
