Temporary traffic signals to be removed with traffic shifted onto temporary bridge

Route 15 is scheduled to be reopened to two-way traffic utilizing a temporary bridge on Saturday morning as a bridge replacement project advances in Lafayette, Sussex County.

Beginning at 8 p.m. tonight, Friday, September 25 until 7 a.m. tomorrow, Saturday, September 26, Route 15 will have alternating traffic using flaggers between the Lafayette Fire House and Morris Farm Road to restripe the roadway and remove temporary traffic signals. Motorists are advised to slow down, use caution and expect delays when traveling through the work zone.

By 7 a.m. Saturday, September 26, the temporary traffic signals will be removed, and one lane in each direction on Route 15 will be restored with traffic shifted onto a newly constructed temporary bridge over Paulins Kill. The traffic shift is necessary to allow for the demolition and reconstruction of the Route 15 Bridge over Paulins Kill. The regular driveway to the Lafayette Pond Park parking lot will remain closed through the duration of the project with access maintained via a temporary driveway that was constructed during an earlier stage.

The work is part of a $4.7 million project to replace the bridge over Paulins Kills, which is in poor condition, in Lafayette, Sussex County. The new bridge will be wider with a 12-foot travel lane, 8-foot shoulder and 6-foot sidewalk in the northbound direction and a 15-foot travel lane and 7-foot sidewalk in the southbound direction. In addition, ADA-compliant sidewalk and curb ramps will be installed on the southbound side to extend the sidewalk to the driveway of Lafayette Center Preservation Foundation/Ludlum-Mabee House. The project is expected to be completed in fall 2027.

The precise timing of the work is subject to change due to weather or other factors.
