Workers on Friday began tearing down a bridge over a Connecticut highway that was damaged in a fiery crash involving a gasoline tanker truck — a project expected to extend the traffic nightmare caused by the closing of Interstate 95 through the weekend.

A day after the crash, crews removed metal fencing on the span in Norwalk before two large excavators — one on each side of the highway — began demolishing the concrete parts of the structure.

Gov. Ned Lamont said the plan is for both sides of the highway to fully reopen by Monday morning’s commute. He and other officials continued to urge drivers to avoid the area.

“And here we are more than 24 hours later. And that bridge is going to be down very soon,” Lamont said at a news conference in Norwalk on Friday.

About 160,000 vehicles travel that section of I-95 in both directions daily, officials said.

The crash happened at around 5:30 a.m. Thursday on the southbound side of the highway.

The bridge removal and road repairs could cost about $20 million, said U.S. Sen. Richard Blumenthal, a Connecticut Democrat.
