MORRIS COUNTY, NJ – Barriers and detours around the bi-county Waterloo Road bridge, which spans Netcong and Mount Olive Township in Morris County and connects with Stanhope in Sussex County, will be removed late this afternoon, Friday, Jan. 8, as the project to replace the bridge nears completion.
The project had forced motorists to navigate 2.5 miles of detours since it began in February 2020.
Waterloo Road bridge, or county bridge number 1401-038, is a single span steel truss originally built in 1894. It carries about 1,100 vehicles per day. The bridge, before replacement, was 18-feet wide and 43-feet long and carried two lanes of traffic – one in each direction.
There also was a steel open-grid sidewalk on the north fascia of the bridge, with an ornamental pedestrian railing. To maintain some of the historic character of the original bridge, the railing and trusses were carefully removed. The trusses were restored and then re-installed. The new 37-foot wide by 40-foot long span has a new, wider ornamental pedestrian rail on the south side of the bridge.
Replacement was needed because the bridge was structurally deficient and functionally obsolete. The superstructure was in poor condition due to severe rust and there had been some loss of the bottom cord of the truss as well as in the floor beams and interior stringers. The bridge had a posted four-ton weight limit.
The contractor on the $2.3 million bid project was Marbro Inc. of Long Branch, and the project was state funded.
The new structure includes pre-stressed concrete box beams supported on stone faced concrete abutments and wing walls, with a concrete deck, curbs, and bridge railings. Work on the approach roadway also was done.
