City of Windsor Heights – 73rd St Bridge Over Walnut Creek

Bridge & Culvert – Design & Rehabilitation

This project consisted of a stage–constructed, custom designed 205′ x 72′ CCS replacement bridge with a sidewalk over Walnut Creek.  Large traffic volumes of approximately 20,000 vpd required that traffic be maintained continuously through the construction site.  Hydraulic design criteria, combined with a custom designed, shallow superstructure, allowed proposed bridge grades to match existing street elevations at this congested urban project site.  A retaining wall and provisions for a bike path under the north span also were incorporated into the project.  Resident engineering and inspection services were provided during construction.
