PRIME AE Awarded the 2017 ACEC RI Gold Anchor Award

July 2017 | PRIME


The Shippee Bridge, which had been in service for more than 70 years, was in a deteriorated condition. It was rated in poor condition by the Rhode Island Department of Transportation (which owns the bridge) due to extensive section loss caused by corrosion. PRIME AE was tasked to identify a bridge replacement alternative.

The selected alternative consists of a precast, pre-stressed butted concrete box beam superstructure/deck system with a span length of 104 ft. It includes sufficient width to accommodate two 11 ft. travel lanes, two 4 ft. shoulders to accommodate bicycles and one 5 ft. sidewalk to accommodate pedestrians. The selected alternative also includes modifications to the existing abutments to reduce their channelizing effect as a means of scour prevention and to minimize the extent of work in and along the watercourse.

The bridge was closed to all traffic on April 4, 2016. The new bridge opened in late July 2016 – ahead of schedule (and on budget).
