anchor Description
This project provides for the replacement of the existing bridge on Redland Road over Mill Creek. The existing single-span concrete slab bridge will be removed and replaced with a new prestressed concrete box beam superstructure and precast concrete abutments and wing walls. The new superstructure will be constructed in the same location. The project also includes approach roadway work at each end of the bridge as necessary to tie into the existing roadway. The bridge and road will be closed to traffic during construction. Accelerated bridge construction techniques will be utilized to minimize the disruption to the traveling public and local community.
anchorEstimated Schedule
The design of the project is expected to be completed in The construction is scheduled to start in the spring of and be completed in the fall of The bridge and road will be closed to traffic from June to August during construction while schools are out of session.
anchor Justification
The existing concrete deck is in need of reconstruction and the existing concrete abutments and slope protections and steel frames and bearings are in need of repairs. The inspection revealed spalls and cracks at the concrete deck, abutments and slope protections, and pack rust, corrosion, and delamination at the steel frames and bearings. The proposed bridge replacement is necessary to provide a safe roadway condition for the traveling public.
