Bridge Structural Improvements
The existing Florence Avenue Bridge carries four lanes of traffic. It is a 218-ft long cast-in-place concrete structure built in 1953 and widened using PC/PS. It is supported on two concrete pier walls. The existing deck has significant deterioration.
IMEG provided assistance to The City of Downey in advanced planning and preparation of the Highway Bridge Program (HBP) funding assistance and estimates for the structural improvements. IMEG performed a field investigation and condition assessment of the existing bridge and provided justification for the replacements of the original superstructure, leaving the substructure and foundation intact. The proposed replacement will be PC/PS construction compatible with the widening section and eliminating longitudinal joints.
