St. Louis County is proposing construction of one grade separated bridge at CSAH 100 railroad crossing in Aurora, MN. The proposed bridge crossing addresses the critical need to ensure connectivity and mobility for the regional transportation network, particularly freight and EMS traffic, in the event of a blockage or closure. Depending on the route, the detour length ranges from 19 to 29 miles. The proposed bridge crossing also responds to existing and projected needs by providing reliable and safe connections for freight, logging, pedestrians, bicycle and recreational vehicle traffic. The Project would create a reliable and sustainable regional transportation network, which is essential for the local economy and the mining and logging industries of the eastern Iron Range.

St. Louis County identified eight items that lend support to the proposed CSAH 100 Railroad Crossing Grade Separation Project.
