Along Route 209 between Leighton and Jim Thorpe exists a rock cut at least 125 feet high. The bedding planes of the bedrock are nearly vertical, posing a high risk of instability. In September 2017, there was a landslide onto the highway, where large boulders fell onto the road. One 50 ton boulder ended up in the center of the road. A remediation construction contract began in 2019 to stabilize the rock slope with rock mesh supported by rock bolts. EEI was engaged to test the rock bolts to demonstrate that roadway will be safer to traffic into Jim Thorpe.
