Hawk Falls Bridge Replacement Project is Progressing

The Hawk Falls Bridge Replacement Project is progressing, with construction estimated to commence in 2021. The replacement Hawk Falls Bridge will be a 720’ long steel structure featuring a 480’ deck arch span flanked by four 60’ deck plate girder spans. As with the current bridge, the new bridge will carry two traffic lanes in each direction, but it will also provide 12’ wide outside shoulders and 6’ wide median shoulders. Three welded, steel box arch ribs will be utilized to create an aesthetically pleasing structure that spans the deep Mud Run Valley located within Hickory Run State Park.
