Crews are stabilizing the rock wall that supports Route 209 with wire mesh and shotcrete, a sprayed concrete, and round-the-clock work at the site will not resume until that phase is finished, the Pennsylvania Department of Transportation said in a press release Thursday.

The stabilization can only be done during daylight hours, according to PennDOT. Once it is complete, contractors will install anchors, build a replacement wall, remove the fallen rock and begin repairing the road.

According to the release, crews began evaluating downslope conditions Monday along the length of the closed stretch, from Jim Thorpe to Nesquehoning. Any problems identified will be repaired as part of the project.

A wall supporting the road collapsed Oct. 31, undermining the roadway and sending rock onto the Reading & Northern Railroad tracks below. No injuries were reported.

The estimate to reopen the highway remains six to eight weeks. PennDOT called the timeframes current estimates subject to change. The railroad line is expected to reopen earlier.

J.D. Eckman Inc. of Atglen is the prime contractor. The firm and its subcontractors have been on site since Sunday.

Route 209 remains closed between Route 903 and Route 93. The posted detour uses Route 443, Route 309 and Route 209.

Scenic train rides have moved rather than stopped. Reading & Northern shifted Lehigh Gorge Scenic Railway departures to the Nesquehoning Regional Railroad Station at 1 Iron Horse Way, where parking is free.

“Tickets originally scheduled for departures from Jim Thorpe will be honored in Nesquehoning,” the railroad said in a Facebook post.
