CENTER CITY (FOX 29) - Officials say a large cave-in has closed the intersection of 20th and Chestnut in Center City.
According to officials, they believe the sewer collapsed at this location and it's not believed to be weather-related.
Cars going northbound will be detoured at Sansom Street and cars traveling east on Chestnut will not be able to go beyond 21st Street.
PWD will have crews on-site Tuesday to begin preliminary assessments of the work that needs to be done to make any necessary repairs, but no timeline is available at this time.
Motorists should avoid the area if possible. If you use public transit, please check SEPTA for the latest, here.
