Sinkhole Repair Shuts Down Route 202 In King Of Prussia For Months

UPPER MERION, PA — Work to repair chronic and debilitating sinkhole issues in King of Prussia has begun, and a stretch of DeKalb Pike will be shut down for months.

Work began Monday between Henderson Road and Saulin Boulevard.

The northbound lanes of the road, which runs concurrent with U.S. 202, will be closed 24/7 through at least early June.

In early June, the work and the closure will switch to the southbound lanes.

"I know this will be difficult, but hopefully this PennDOT project will stop the sinkholes on U.S. 202 once and for all," Upper Merion Supervisor Greg Waks said in a statement. "This isn’t the first time there has been a major road closure in Upper Merion in recent years. Church Road, Balligomingo Road and Allendale Road have all seen lengthy closures in the past decade. We made it through that and we will make it through this, too."

Traffic will be impacted in the surrounding area, officials said.

The plague of sinkholes over the past several years has crippled traffic along 202 and near the King of Prussia Mall and Turnpike.

Crews will drill a series of holes in the pavement in a grid pattern and inject pressurized grout, a substance that moves like liquid and turns into solid. The hope is that the grout will move to fill the "subsurface voids" that exist all over the area and which cause the sinkholes.
