A 10-foot deep hole that opened Wednesday afternoon on I-95 North has been repaired in time for the Thursday morning commute, the State Highway Administration said.
All lanes are open.
Highway crews suspected the collapse of a drainage pipe opened the hole that caused massive backups during the Wednesday evening commute.
The hole was about 5 feet wide and 10 feet deep, said Charlie Gischlar, spokesman for the State Highway Administration.
Wednesday evening traffic was blocked from two right lanes on northbound I-95 north of Route 100 in Howard County and near the border with Baltimore County.
The collapse happened about 4:30 p.m., just before the evening commute, Gischlar said.
"The worst time ever," he said. "It's a main feeder route."
He urged drivers to avoid the interstate while crews fill the hole with concrete.
