FINAL TOUCH TO BRIDGE REPLACEMENT WILL CAUSE ONE-DAY TRAFFIC DELAYS — SEEK ALTERNATE ROUTE ON TUESDAY
Approaches to the busy Mendham Road Bridge in Morris Township will be milled and paved on Tuesday, putting finishing touches on a bridge replacement project that was mostly completed in July, but still requires an improved road surface on both ends of the bridge.
The paving work will address approximately 100 feet of Mendham Road, or County Route 510, on each side of the bridge.
Work is set to start at 7 a.m. and last through the day.
Resultant motoring delays are expected Tuesday on the commuter route between Morristown and the Mendhams, Chesters and Washington Township.
Virtual message boards announcing the milling and paving work were installed near the bridge last week to give motorists a warning to expect delays and to consider a one-day alternate route to and from work or school.
Physical replacement of the 118-year-old Mendham Road Bridge was completed on time in July.
The contractor, Konkus Corporation of Chester, subsequently adding the stone bridge facing, guide rail, and site restoration work, all of which were part of the $1.62 million county funded job. Paving of the approaches will complete the entire project.
The original Mendham Road Bridge, which accommodated about 17,000 per day, was built in 1898 and was widened in 1950. It was a single span structure with steel stringers and a reinforced arch deck with masonry stone substructures.
The old structure was 13-feet long and 49-feet wide. It had to be replaced due to severe rust and section loss of the steel stringers, with cracks throughout the asphalt roadway and an undermining of the foundations.
The new structure is a precast concrete arch. The bridge parapets are stone faced with a bluestone coping, and the substructure is also stone faced. The roadway curb-to-curb width is approximately 46 feet and the overall structure width is 49 feet.
