No Through Traffic on Pleasant Hill Road in Mount Olive; Separate Detours for Cars and Trucks

Pleasant Hill Road in the Flanders section of Mount Olive Township will be closed to through traffic beginning Monday, Aug. 31, after the morning rush hour, as Morris County replaces two bridges over Drakes Brook.

The bridge closures will require motorists to follow a signed detour via Reger Road and Ironia Road. Truck traffic will be directed on a separate detour via Furnace Road and Route 206.

The project is expected to take approximately four months to complete, weather permitting.

The two existing bridges, located adjacent to each other near the Flanders Valley Golf Course, have deteriorated over time and require replacement. The bridge closest to the north side of Pleasant Hill Road, nearest to Ironia Road, was built in 1900 and has severe rusting and section loss in its steel beams. The second bridge, built in 1940, also has rusting steel beams as well as voids in its foundations.

The circa 1900 bridge will be replaced with a prestressed concrete beam bridge with a concrete deck, stone-faced parapets and wingwalls. The circa 1940 bridge will receive a three-sided precast concrete frame with precast wingwalls and bridge railings, topped with an asphalt overlay.

Motorists should anticipate delays and are advised to drive with caution. Alternate routes are encouraged during construction.

The $2,608,664 project is being completed by Konkus Corporation of Hillsborough, N.J., under contract with Morris County.
