Milling and Resurfacing Projects

Hamilton Avenue (CR 606), City of Trenton

Until further notice, milling and resurfacing on Hamilton Avenue (CR 606), between Chambers Street and S. Olden Avenue in the City of Trenton has been postponed. The duration of the project is approximately three (3) weeks, weather permitting.

During construction, Hamilton Avenue would be closed to through traffic from 9 a.m. to 3:30 p.m., Monday through Friday.  Motorists would be directed to use Chambers Street, Greenwood Avenue and S. Olden Avenue.  However, access would be permitted for local businesses and residents.

Bridge Replacement Projects

Woosamonsa Road over a Tributary to Baldin's Creek (MC#236.4), Hopewell Township 

Until further notice, replacement of Mercer County Structure No. 236.4, which carries Woosamonsa Road over a Tributary to Baldwin's Creek, located between Burd Road and NJ State Route 31 in Hopewell Township  has been postponed. Due to advanced deterioration of the masonry work, especially near the water line, the structure is susceptible to failure during high flooding events.  Therefore, full replacement of the structure has been deemed necessary as soon as possible.

Construction will take place from 9 a.m. to 3:30 p.m., Monday through Friday and will be completed using in-house personnel.  Mercer County anticipates the project will require approximately sixty (60) calendar days to complete, weather permitting.  During construction, Woosamonsa Road up to the bridge will be open to local residents. However, the bridge will be fully closed to through traffic.  A detour will be posted directing motorists to use Burd Road, Pennington-Harbourton Road (CR 623) and NJ State Route 31.

Church Street (CR 609) over Doctors Creek (MC#672.2), Hamilton Township 

On or about Wednesday, March 18, 2020, a bridge replacement project will commence on Mercer County Structure No. 672.2, which carries Church Street (CR 609) over Doctors Creek in Hamilton Township.  The structure is located between NJ Route 156 and Main Street in Groveville.  While the overall project is to be completed in 210 calendar days, weather permitting, the allowable duration of the road closure is 180 calendar days.

During construction, the bridge will be closed to all traffic on a 24/7 basis.  The contractor, Marbro, Inc. will install advance notification signs prior to the start date advising motorists of the upcoming road closure.  A detour will be posted directing motorists to NJ Route 156 to South Broad Street to Main Street.

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.
