COUNCIL BLUFFS, Iowa (AP) — A stretch of eastbound Interstate 80 that was closed after a roadway shoulder collapsed in Council Bluffs should be reopened by later Thursday morning, an Iowa Transportation Department engineer said.
District 4 engineer Troy Jerman said the pavement patch should be cured and ready for use after 8 a.m.
A portion of the interstate shoulder collapsed about 8:15 p.m. Wednesday as workers were installing a pipe under the roadway, Jerman said. A void that ran under the eastbound lanes was discovered, so they were closed to traffic. No accidents or injuries were reported.
Repair crews had to cut away 10-foot stretches of the three lanes so they could reach the void, which ran two to three feet deep. They filled the void then poured the cement that had an expected curing time of about four hours, Jerman said.
It's unclear what caused the void, he said. Several pictures were taken and officials will search for other clues once they have enough daylight, Jerman said.
Drivers trying to cross from Nebraska into Iowa had been advised to seek other routes on Thursday. They were directed north to the Interstate 680 bridge or south to the Veterans Memorial Bridge in southern Omaha.
Westbound lanes remained in use.
