Frazier Creek Bridge Replacement Project
NOE - Notice of Exemption
The purpose of the project is to replace the Frazier Creek Bridge. The new bridge will be in the same location but will be longer and more fire-resistant than the previous bridge. It will be a prefabricated steel bridge with steel girders and structural steel decking and asphalt pavement fill. The new bridge will be 54 feet long and 20 feet wide with a single travel lane, similar to the previous bridge. The existing approaches vary from 18 to 20 feet in width, and the new approaches will be 22 feet wide with two 10-foot lanes and transition on either side of the bridge into the existing roadway to accommodate the turning radii of the approaching curves. The new approaches will extend about 100-150 feet down the road from either side of the bridge. The existing wooden abutments will be removed, however the existing concrete footings will be left in place and used to help protect the new abutments. New abutments and wingwalls faced with concrete blocks will be installed behind the original abutment locations. Riprap will be placed in front of the new abutment walls and wings.
