Pennsylvania Department of Transportation crews are inspecting bridges in the state as a precaution.
“We have no reason to believe the Virginia earthquake caused major damage to any state roadways or bridges,” said Scott Christie, PennDOT’s Deputy Secretary for Highway Administration, in a prepared release. “But to err on the side of caution, we are assessing those bridges that could be susceptible to quake damage.”
PennDOT will first inspect bridges that are at least 200 feet long or longer and at least 60-feet high. The inspections will continue through at least Wednesday.
