Somerset County Bridge: A Precast Replacement Solution

Precast concrete played a prominent role in constructing the new Somerset County Bridge - a distinguished precast, reinforced concrete arch structure, which replaced an old deteriorated highway bridge in Somerville, New Jersey. The new crossing comprises two precast, reinforced concrete curved members to form a 60 ft (18.3 m) clear span with a 9 ft 6 in. (2.90 m) rise and a 50 ft (15.2 m) width. The overall length of the structure, including retaining walls, is 90 ft (27.4 m). The bridge incorporates 18 precast panel components that mimic the look of stone as well as 120 precast balusters made with white concrete. The precast concept used in this project is being advocated by county officials as an example for other damaged or new arch bridges in a similar span range.
