This project included the construction of approximately 600’ of an off-road multi-use trail adjacent to CSAH 1 in Carlton, MN. The trail was incorporated into the rehabilitation of Bridge L1182 over Otter Creek. This trail also provided an important regional connection to the Willard Munger State Trail. Other improvements included: grading, aggregate base, bituminous trail paving, railroad crossing accommodations, and bridge rehabilitation/widening. The existing bridge improvements included the removal/rehabilitation of end treatments on both sides of the bridge and the existing cast in place structure was extended on the east side to accommodate the proposed trail.

This Project Memorandum included a social, economic, and environmental study that analyzed the impacts of this project on historic properties, endangered species, right-of-way, water quality, wetlands, floodplains, noise, and air quality. It also included the evaluation of alternate transportation corridors and design alternatives, and incorporated public involvement.
