Project Overview
This project consisted of the construction of a mountain bike trail for the Munising Bay Mountain Bike trail system. Arete’ Structures designed and supplied a 36ft x 6ft fiber reinforced polymer (FRP) bridge to help in connecting an existing parking lot to the existing mountain bike trail system. The bridge was built on a steep terrain and installed by Wuebben Construction of Dollar Bay Michigan. The bridge was completed in the fall of 2017.
