I-80 westbound remains closed and detoured at Exit 34B until further notice following a new sinkhole that formed in the median on Wednesday, 03-19-25, in Wharton, Morris County. 

Shortly after 5 p.m. Wednesday, March 19, an approximately 15-foot by 15-foot hole opened in the median in the I-80 eastbound work zone. Out of an abundance of caution, NJDOT closed and detoured all lanes on I-80 westbound at Exit 34B/Route 15 northbound. NJDOT has created the following webpage to keep the public informed about progress of repairs: https://dot.nj.gov/transportation/commuter/roads/i80/ .

Traffic Mitigation

Due the significant impact of the closures, GPS and other map services may reroute traffic onto local roads that are not designed to handle commercial vehicles or increased traffic volume. This is particularly important for trucks as there are low bridges and weight restrictions on many roads in the area. 

Please remain on the designated detours or alternate routes. Follow all posted signs and regulations, and if you are approaching an intersection, please “Don’t block the box.” 

In addition, NJDOT is using technology to send messages to commercial truckers to provide information about the closure, detour, and alternate routes. The Department is also using digital messaging signs and working with our regional transportation partners to share information so drivers can make informed decisions about potential alternate routes to take
