The sinkhole, Johnson explained, looks like a three- to four-foot-wide hole from the surface, but in fact tunnels under all lanes of the road. Engineers will need to examine and stabilize it before cars can cross again.
Rush-hour traffic has been diverted off of U.S. 50 and onto Route 665. After about a mile, cars can enter U.S. 50 again, Johnson said.
Johnson said that the opening of the hole caused no damage to cars or injuries to travelers. He said the cause of the sinkhole was unknown.
