This project was a rehabilitation design of the Highway 965 Bridge over the Iowa River in Johnson County. The project consisted of a feasibility study, preliminary design, final design, and construction engineering services. The bridge was constructed in 1956 and is a four span, 432 foot steel girder bridge with a 28 foot wide roadway. Deterioration of the deck forced the southbound lane to be closed. The rehabilitation included removal and replacement of the bridge deck meeting current width requirements, open guardrails, approach pavement, cleaning and zone painting existing girders, strengthening of girders in some areas, and substructure concrete repairs. To minimize the bridge being reduced to a single lane, the design phase was only 45 days. The design was completed on schedule and within budget. Construction was completed on schedule in Fall, 2016.
