Monmouth Street (Bridge No. 140.8), City of Trenton
On December 5, 2019, Monmouth Street between East State Street and North Clinton Avenue was closed to all traffic due to emergency bridge repairs. Rehabilitation of the bridge, officially known as Mercer County Bridge #140.8, which carries Monmouth Street over Assunpink Creek is scheduled to be completed in 150 calendar days, weather permitting.
The existing bridge structure is a single span and is simply supported, consisting of concrete encased steel beams supported on full height abutments built on piles. The bridge is considered Structurally Deficient due to the serious condition of the deck, with sufficiency rating of 78.0 out of 100.
The rehabilitated bridge will have steel stringers with precast deck, concrete bridge approach slabs, concrete pedestals, concrete bridge pylons and 4-bar open steel bridge railings. Roadway work includes hot mix, asphalt paving, new striping, new guiderail and approach guiderail systems, excavation, top soiling and seeding.
The proposed cross section at the bridge will consist of two 12-foot travel lanes, two sidewalks and two shoulders with 4 rail bridge railings.
