FALMOUTH — The Maine Department of Transportation is replacing the bridges that carry Bucknam Road and Johnson Road over I-295 in Falmouth. The existing bridges date back to the creation of the interstate. They were built in 1960 and are approaching the end of their useful service lives.

The Bucknam Road Bridge replacement is happening first and will occur in two phases. On-site work began in September.

Drivers should expect nightly lane closures on both the northbound and southbound sides of I-295. These closures will occur on Sunday through Thursday nights between the hours of 8 p.m. and 6 a.m. the following day. Single lane closures on Friday nights will only be permitted on the southbound side of the interstate between 10 p.m. on Friday and 6 a.m. on Saturday.

Full closures of I-295 (northbound and/or southbound) will be permitted Monday through Saturday between 1 a.m. and 5 a.m. Any full interstate closure will not last longer than 25 minutes.

On Bucknam Road, lane closures are permitted on Sunday through Thursday nights between the hours of 7 p.m. and 6 a.m. the following day.

Starting after November 27, there will be occasional full closures of Bucknam Road between the I-295 northbound and southbound ramps. These closures will occur on Sunday through Saturday nights between the hours of 10 p.m. and 5 a.m. the following day.

Clearly marked detours will be in place during all full closures.

Work on Bucknam Road will continue into 2024. On-site work on Johnson Road has not yet begun. The estimated completion date for both bridge replacement projects is December 12, 2025.

The contractor on this project is Wyman & Simpson, Inc. of Richmond. The contract amount is $19,574,460.
