HAMPDEN, Maine — The state of Maine is replacing eight highway bridges and rehabilitating a ninth on a stretch of Interstate 95 near Bangor.

The project is expected to take until the end of November 2022 and cost a little less than $45 million. The Maine Department of Transportation said the bridges are all located on a four-mile piece of I-95 in Hampden.

The bridges are almost 60 years old and approaching the end of their usefulness, the department said. The project will affect traffic on both sides of the interstate, it said.

Some of the bridges involved in the work carry the interstate over Soudabscook Stream, a tributary to the Penobscot River.

The transportation department said it hopes to maintain all four lanes of traffic during the work, but diversions will be necessary.
