Starting this past April 6, the Maine Department of Transportation (MaineDOT) began 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 Ave. with a single span bridge. A median cross-over using 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. 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 Ave. 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 Ave. Bridge closure is scheduled to start in 2027. Work is expected to be completed in 2029.
The contractor for this project is Cianbro Corporation of Pittsfield, Maine, and the contract amount is $53,820,000.
