PennDOT announced on April 23rd that a portion of Chemical Road will remain closed from Metroplex Boulevard to just west of Germantown Pike in Plymouth Meeting (Plymouth Township) due to severe underground sinkhole conditions.
Also remaining closed will be the ramp from northbound Interstate 476 to Chemical Road (Exit 19). During the ramp closure, northbound I-476 motorists will be directed to use the next exit (Germantown Pike/Exit 20) to access Chemical Road.
Both closures will be in place 24 hours a day/seven days a week until PennDOT completes an upcoming project to address stabilization concerns and underlying voids beneath this area of the highway. The work is expected to begin this summer and finish by the end of the 2021.
During the closure of Chemical Road, motorists will be directed to use Gallagher Road, Belvoir Road, Sandy Hill Road, and Germantown Pike. Local access will be maintained for local businesses and residents.
The highway has been closed since March 26th.
