NJDOT to Install Temporary Bridge on Route 15 Southbound Over Rockaway River
Two Lanes of Traffic Expected to Be Restored in Six Weeks
Jefferson Township, NJ – The New Jersey Department of Transportation (NJDOT) has announced plans to install a temporary bridge on Route 15 southbound over the Rockaway River in Jefferson Township, Morris County. This measure aims to restore two lanes of traffic while the 124-year-old bridge undergoes replacement.
On Monday, June 3, southbound traffic was reduced to one lane after movement was observed on the bridge abutments. By Tuesday, June 4, the roadway showed signs of distress, prompting NJDOT to close the bridge entirely to ensure public and worker safety.
The temporary two-lane bridge structure, which will span the existing closed bridge, will be delivered and installed on an accelerated schedule. The installation is expected to be completed and open to traffic within six weeks, although weather and unforeseen factors could cause delays.
NJDOT continues to work with local officials to address concerns, monitor traffic, and adjust signal timings on the detour route to mitigate congestion. A dedicated website is being developed to provide project updates and additional information to the public. Motorists are encouraged to check NJDOT’s traffic information website, 511nj.org, for real-time travel information.
Local businesses on Route 15 southbound remain open and accessible via a designated lane.
The $11.6 million project will replace the Route 15 southbound bridge with a single-span concrete box beam structure featuring two 12-foot-wide travel lanes, 10-foot-wide inside and outside shoulders, and sidewalks on both sides. The new bridge will improve roadway geometry and sight distance. The project will advance in stages to minimize the impact on motorists, with NJDOT providing advance notice of any lane or ramp closures.
The new bridge construction is expected to continue on an accelerated schedule, aiming for completion by fall 2025. The precise timing of the work may change due to weather or other factors.
