SCOPE
The project consists of demolition and removal of the existing 50-foot long single-lane bridge with steel stringers and laminated timber deck on reinforced concrete abutments, and construction of a new bridge that will occupy essentially the same alignment as the existing structure. It has been designed as a two-lane structure, 114 feet long and 29 feet wide, with metal tube bridge railings mounted on curbs. The new bridge approaches will be approximately 125 feet in length and will conform back to the existing roadway. The new bridge will be constructed of precast concrete voided slab elements supported on cast-in-place concrete substructures founded on driven pile supported foundations. Traffic will be detoured away from the construction zone utilizing an existing access to the creek that will be improved to serve as a temporary crossing. The crossing will be constructed with culverts to carry any low flows that may be present during construction and will be removed and restored to pre-project conditions following project construction
