The project includes the replacement of an existing paved two-lane bridge located on Avenue 392, crossing Sand Creek. The existing bridge is a 77 foot long and 22 ft wide, 4-span, board formed concrete bridge that was built in 1939. Due to the narrowness of the roadway, the bridge is considered to be functionally obsolete. The existing bridge will be replaced with a new concrete structure and rock slope protection along Sand Creek. The new structure will be 104 ft in length, 10.1 ft in total depth, 35 ft in total width including two 16 ft travel ways, and will span the approx width of the channel to accommodate a 50 year design storm. The bridge will conform to the existing roadway approach width and a max of 400 ft of new roadway approach will be constructed to tie into the existing roadway approaches on both sides of the bridge. The bridge profile may be raised to provide adequate freeboard over the design hydraulic flows. No permanent ROW acquisition is anticipated; however, temporary construction easements along both sides of the bridge will be needed to conduct construction-related activities. Avenue 392 will be closed to through traffic during construction and a detour to the south on Avenue 388 will be provided. The project will also involve relocation of at least one electric utility pole; possibly two. The utility pole nearest the bridge is located on County ROW and will be relocated to a yet to be determined location. It has not yet been determined if the second pole, also southeast of the project site, requires relocation.
