AUGUSTA — A failed bridge joint that prompted an emergency repair and a lane closure Monday night on Interstate 95 in Augusta has been patched and is expected to last until more permanent repairs can be made in September, officials said.

A hole appeared Monday at a joint on the bridge that carries the southbound lanes of I-95 over Bond Brook Road and Bond Brook.

A region manager for the Maine Department of Transportation spotted the hole while driving on the bridge, according to officials.

The southbound travel lane was closed Monday afternoon and evening so a crew could patch it, filling the hole with a concrete material.

The same lane was closed for a while Wednesday so a contractor could take measurements for steel that is to replace the failed bridge joint.

Officials with the Maine DOT said the bridge joints were already scheduled to be replaced in September, and the patch is expected to last for several weeks, until the replacement project gets underway.

“The patch is safe to drive over until the replacement work starts next month,” Paul Merrill, spokesman for the state DOT, said.

Thomas Roberts, a region manager for the department, said the bridge joints in the northbound and southbound lanes are expected to be replaced, beginning Sept. 9.

The Augusta bridge, between exits 109 and 112, is not the one now in the midst of a replacement project. That is the Western Avenue Bridge, which is just to the south and carries U.S. Route 202 over I-95.

The Western Avenue Bridge is being replaced in a project involving the construction and use of a temporary bridge. The project is expected to conclude in 2026.
