Overhead Bridge Work to Close Northeastern Extension Overnight on Sept. 20
I-476 will be shut down between Mid-County and Lansdale for six hours.


The Pennsylvania Turnpike Commission cautions motorists that an 11-mile stretch of the Northeastern Extension (I-476) will be closed in both directions for six hours on Sept. 20 between the Mid-County (Exit #20) and Lansdale (Exit #31) interchanges. The closure is necessary for the protection of motorists and workers during the removal of beams from the overhead ramp-bridge that carries traffic to and from the Lansdale Interchange in Towamencin Township, Montgomery County.

At 12:01 a.m. on Sept. 20, southbound traffic will be diverted off at the Lansdale Interchange. At the same time, northbound access to the Northeastern Extension from Mid County will be prohibited. Motorists wishing to travel north from the Mid-County Interchange or the east/west Turnpike mainline will be directed to exit I-276 at the Fort Washington Interchange (Exit #339) to return to I-476 at Lansdale. The Northeastern Extension will reopen to traffic by 6 a.m.

Prior to the shut-down, starting at 9 p.m. on Sept. 19, motorists traveling northbound from Mid-County and southbound from Quakertown should be prepared for a single-lane traffic pattern in both directions approaching the Lansdale Interchange. The speed limit will be posted at 55 mph until the patterns are lifted by 9 a.m. Construction-zone speed limits are enforceable and fines will be increased.

Pennsylvania State Police and Turnpike personnel will be positioned at the Lansdale, Mid-County and Ft. Washington interchanges to assist motorists. Drivers can tune to radio 1640 AM for detour information and traffic conditions. Changeable message signs will also provide updated information regarding closures and detours. Motorists are encouraged to plan travel accordingly.
