BANGOR — Starting on April 6, the Maine Department of Transportation (MaineDOT) will begin clearing and preparing the median between I-95's northbound and southbound lanes to begin the process of replacing three major I-95 overpasses in Bangor.

This is part of a long term project that involves replacing the two I-95 bridges over Stillwater Avenue with a single span bridge, according to MaineDOT, in a news release.

A median cross-over utilizing the new northbound alignment will be put in place to maintain through-traffic during construction.

"While some traffic delays will be necessary as the bridge supports are put in place, no extended detours will be needed," said MaineDOT.

There will be periodic short-term closures of Stillwater Ave and Exit 186 ramps requiring detours. Access to businesses and the pedestrian path will be maintained at all times.

The Kenduskeag Avenue Bridge will be replaced with a shorter, higher clearance bridge span. The decision to fully close the bridge will shorten the duration of the construction period, and a detour will be established for the approximately eight-month closure. Cianbro will begin making safety improvements to the three-mile detour route on Valley Avenue starting later this year. The Kenduskeag Avenue Bridge closure is scheduled to start in 2027. Work is expected to be completed in 2029.

Traffic updates will be available to the public on local media and through the MaineDOT Facebook page. Variable message signs will alert motorists of traffic changes.

The contractor for this project is Cianbro Corporation of Pittsfield, Maine.

The contract amount is $53,820,000.
