The previous bridge was permanently closed in May 1978. Demolition was delayed by court rulings until July 1980. Further "red tape" stalled the start of construction until Spring of 1982. Steel was placed for the new spans in late 1984. The new bridge opened November 1, 1986.

The Gannett Fleming website states: "Placed along the same alignment as the original deteriorated structure, the new bridge incorporates four lanes with a barrier median and a five-foot sidewalk. The nine-span bridge reaches a total length of 1,535 feet between abutment bearings. This project received the 'Outstanding New Bridge Design 1986' Award given by the Association for Bridge Construction and Design and the AISC '1989 Prize Award for Medium Span High Clearance.' "
