I-78 in Hunterdon County to Experience Temporary Stoppages for Rockfall Mitigation

Project Resumes with Daytime Blasting Operations Through Summer 2024

The New Jersey Department of Transportation (NJDOT) has announced the resumption of a critical rockfall mitigation project on Interstate 78 in Bethlehem, Hunterdon County, following a winter break. 

Starting next week, motorists should prepare for temporary stoppages in both directions of I-78, attributed to necessary blasting operations to enhance roadway safety.

The project, which focuses on a section of I-78 between milepost 9.96 and milepost 10.55, will involve daytime blasting from 9 a.m. to 2:30 p.m., Monday through Saturday, extending through summer 2024. 

These operations are expected to cause 20-minute traffic halts in both directions of I-78, with the New Jersey State Police facilitating the temporary closures. 

NJDOT advises drivers to anticipate delays, exercise caution, and consider alternative routes during these periods. Notification will be provided in advance of any extended lane closures.

With a budget of $32.9 million, primarily from federal funds, this project aims to reduce rockfall risk along this vital interstate corridor. 

The mitigation efforts include rock scaling to trim the slope and excavation to expand the catchment area, preventing rocks from reaching the highway. 

Additionally, the project will enhance drainage systems in the area. Completion is anticipated by fall 2024.

Motorists are encouraged to remain vigilant when navigating through the construction zone, adhere to posted speed limits, and respect the guidance of law enforcement and traffic management personnel. 

The temporary inconveniences are in service of long-term improvements to road safety and reliability on one of New Jersey's key transportation routes.
