Extensive Construction on US 46 and Major Routes Causes Delays Across Morris County

Multiple lane and shoulder closures affect travel times for motorists on US 46, I-287, and NJ 10 through Parsippany-Troy Hills, Denville, and surrounding areas.

MORRIS COUNTY, NJ - Ongoing construction across major roads in Morris County, especially on US Route 46, is creating significant delays for drivers. As of today, motorists are advised of numerous closures and lane adjustments affecting US 46 in both directions, with work expected to continue until 3:00 p.m. These closures affect areas in and around Parsippany-Troy Hills, Denville, Rockaway, and Montville Townships, creating challenges for commuters and travelers.

Primary Construction on US 46:

• In Parsippany-Troy Hills, construction on US 46 affects both directions near I-287, where multiple lanes and shoulders are closed from 9:00 a.m. to 3:00 p.m. Westbound traffic has closures in the right lane and shoulder, while eastbound has left lane and shoulder closures.
• Further west on US 46, eastbound lanes near CR 644/Main St in Rockaway Township have deceleration lane closures, contributing to slowdowns.
• Multiple sections near I-80 in Denville also have lane and shoulder closures on both eastbound and westbound sides, with a focus on maintaining safe traffic flow despite reduced lane availability.

Broader Impact on US 46:
Additional closures affect areas stretching from Mountain Lakes to Fairfield Township. Notably, in Mountain Lakes, lane closures on US 46 span both eastbound and westbound lanes between CR 618/Mountain Lakes Blvd and CR 654/Cherry Hill Rd. These extensive closures are expected to impact local traffic until the afternoon.

Other Affected Routes in Morris County:

• I-287 northbound near Morristown has a right lane closed between exits 35 (NJ 124) and 41 (I-80), with construction scheduled until 2:00 p.m.
• On NJ 10 eastbound from CR 665 in Randolph Township to Yacenda Dr in Parsippany-Troy Hills, one right lane will be closed until 3:00 p.m.
• I-280 westbound near Exit 1W (New Rd) in East Hanover Township also has right shoulder closures during construction hours, adding to regional delays.

Traffic Advisory and Recommendations:
Motorists are urged to consider alternate routes or allow for additional travel time, especially along US 46, where construction affects multiple intersections, exits, and deceleration lanes. Drivers should remain alert for sudden lane changes, reduced speeds, and posted construction zone signs as crews work to complete road improvements.
