The 90-year-old Main Street bridge in Mendham Township, which runs over Harmony Brook, has been reopened to traffic slightly ahead of schedule following structural repairs that were completed on Monday afternoon. But finishing touches will continue for the next week and a custom made bridge railing won’t be installed until early 2016.

Main Street Bridge in Mendham Township Re-Opened on Monday

Even though the road was opened to vehicular traffic, the stone facing, roadway stripes and guide rail still need to be installed. Work on those items is expected to be done by the end of next week.

Also, a bridge railing is being custom made and will not be delivered to the site for another 8 to 10 weeks, when installation will commence, and the project will be totally completed.

Construction began on Nov. 16 to replace the bridge, which was a 22-foot long, 37-foot wide span that was built in 1925 and previously rehabilitated in 1977. The closure caused detours on East Main Street, sending traffic to Woodland Road, Cold Hill Road, Cherry Lane and Mendham Road (Route 510).

The $716,862 contract for the job was awarded to Konkus Corp. of Chester, through public bidding.

The Main Street bridge is a single span steel stringer structure with stone masonry substructures. The bridge carries about 2,950 vehicles a day.

The new structure is a precast, three-sided frame with stone facing. It will have white ornamental railing to mimic the original railing on the bridge.

A concrete sidewalk was added to the north side of the bridge (Woodland Road side) for pedestrian safety. The road width did not change.

The old bridge’s span’s steel stringers were severely rusted and its deck pans deteriorated resulting in portions of the asphalt roadway becoming loose and potholes forming across the bridge deck surface.
