PennDOT’s contractor used flowable fill to pack the void until an elevation was reached where the roadway base could be installed, followed by final paving, according to PennDOT.
The Pennsylvania Department of Transportation announced early Saturday that Plymouth Road was opened in both directions between Rittenhouse Square and Butler Pike in Plymouth Township, Montgomery County, following sinkhole repair.
Northbound Plymouth Road was closed on Friday, May 3, following the discovery of pavement settlement. In addition, southbound Plymouth Road was closed May 14, to expand excavation activity into the southbound lanes.

The right turning lane into an apartment complex had been inaccessible for the several weeks, a move PennDOT Community Relations Coordinator Robyn Briggs said was required to monitor the area.
The same area was originally closed Feb. 2, as the roughly 15-by-15-foot sinkhole was originally cordoned off. The road was shut down for about a week before reopening to traffic.
Around 9,700 vehicles travel along the Plymouth Township road each day. The thoroughfare connects to major regional arteries such as Interstate 476 and the Pennsylvania Turnpike.
