Route 15 southbound lane overnight lane closures this week as bridge replacement project advances in Jefferson, Morris County Overnight lane closures needed to implement traffic shift

(Trenton) – Route 15 southbound is scheduled to have overnight lane closures this week as the Bridge over Rockaway River replacement project is scheduled to begin next week in Jefferson, Morris County.

Beginning at 8 p.m. tonight, Wednesday, July 5, until 5 a.m. Thursday, July 6, and continuing Thursday and Friday nights at the same time, one lane on Route 15 southbound is scheduled to be closed for pipe work, rumble strip removal and to implement a traffic shift. One lane will be maintained each night.

By 5 a.m. Saturday, July 8, traffic will be shifted to the right using the existing shoulder as a travel lane. The traffic shift is necessary to create a work zone to demolish and reconstruct the left side of the bridge. Two 11-foot-wide lanes will be maintained during construction.

The $11.6 million project will replace the Route 15 southbound Bridge over the Rockaway River. The new bridge will be single-span concrete box beam structure with two 12-foot wide travel lanes, 10-foot wide inside and outside shoulders, and sidewalks on both sides of the bridge. The new bridge will improve the roadway geometry and improve sight distance. The project will advance in stages with two lanes of traffic maintained on Route 15 southbound during peak travel times. NJDOT will provide advance notice of any lane or ramp closures. The project is expected to be complete in the fall 2025.

The precise timing of the work is subject to change due to weather or other factors. Motorists are encouraged to check NJDOT’s traffic information website for real-time travel information. For NJDOT news follow us on Twitter @NewJerseyDOT and our Facebook page.
