A contractor was working on it Thursday when the erosion started to accelerate on a nearby road. Officials say the sinkhole didn’t swallow any vehicles, and there were no injuries. Signs have been placed along the highway directing traffic to a detour. ODOT spokesman Jared Castle says drivers can expect delays of five to 10 minutes.

The agency plans to get bids from contractors so repairs can start quickly, but repairs could be upwards of $4 million according to ODOT. Castle says ODOT wants the road partially opened within a week, but the entire repair could take eight weeks.

Sink Holes: Buried Alive

His body was never found. Bush was a victim of a sinkhole—a worldwide hazard that lurks wherever limestone and other water-soluble rocks underpin the soil. When carbon dioxide from the air dissolves in rainwater, it forms a weak acid that attacks soft rocks, riddling them with holes like Swiss cheese. Sinkholes can occur gradually when the surface subsides into bowl shaped depressions or suddenly when the ground gives way. These geological hazards have swallowed highways, APARTMENT buildings, horses, camels, even golfers, with monster-size holes cracking the earth from Siberia to Louisiana. Filled with compelling eyewitness video of dramatic collapses, and following scientists as they explore the underlying forces behind these natural disasters, NOVA travels the globe to investigate what it’s like to have your world vanish beneath your feet.
