A portion of the Northeast Extension (I-476) will be shut down for several hours overnight into Sunday morning.
Starting at midnight, an 11-mile stretch of I-476 will be closed in both directions for six hours between the Mid-County (Exit 20) and Lansdale (Exit 31) interchanges due to overhead bridge work. During the closure, workers will remove beams from the overhead ramp bridge that carries traffic to and from the Lansdale Interchange in Towamencin Township, Montgomery County.
Southbound traffic will be diverted off at the Lansdale interchange while northbound access to the Northeast Extension from Mid-County will be prohibited. Motorists who want 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. I-476 will reopen to traffic at 6 a.m. Sunday.
