Crews make repairs on Route 30 Bypass in Downingtown after sinkhole opens in roadway

DOWNINGTOWN, Pennsylvania (WPVI) -- All lanes are back open after PennDOT crews quickly made repairs to a sinkhole on a busy highway in Chester County.

Chopper 6 was overhead Monday as workers filled in the large hole under the center median on the Route 30 Bypass in Downingtown between Route 113 and Wallace Avenue.

Several lanes were closed to allow space for the repair work.

PennDOT is looking into what caused the sinkhole.
