BANGOR, Maine — Maine Department of Transportation bridge maintenance workers are spending Monday and Tuesday removing loose concrete from an Interstate 95 overpass after three vehicles were damaged Friday night by debris that fell into the roadway.
Two vehicles wound up with tire damage and a third had a damaged rim after they struck chunks of concrete that had fallen from the Access Road to the former Air Force ammunition dump. It is the first overpass south of Exit 182 for Interstate 395, according to the state transportation department.
Spokesman Ted Talbot said Monday the problem with the falling concrete is the result of the 1960s-era span’s design, which he said is a steel stringer bridge with a concrete deck. The MDOT regularly chips loose concrete from the decks of those kind of bridges as part of its routine maintenance program, he said.
“We’d like to get ahead of these, but unfortunately it happened this way,” Talbot said.
Talbot said the bridge is otherwise in good condition and is not scheduled to be replaced.
“It’s structurally sound and perfectly safe,” he said. When it does get replaced, its design will be improved, he said.
“We don’t build those anymore,” he said of the steel stringer design.
No injuries were reported in connection with the fallen debris, the Maine State Police confirmed.
Talbot said the maintenance work, which is occurring in the north and south bound lanes, should be completed by the end of Tuesday.
