Crews have begun the construction of a new interchange on Interstate 95 at Trafton Road in Waterville, transportation officials said.

The project consists of a half-cloverleaf pattern at Trafton Road near the Sidney town line, allowing motorists to get on or off in either the north or southbound direction, the Maine Department of Public Safety said in a news release Wednesday.

Additional work necessary to accommodate the interchange will include upgrades to the Trafton Road overpass bridge, drainage improvements to Eight Rod and Trafton Roads and the addition of turning lanes at the intersection of Trafton and West River Road.

According to the release, the majority of work will be conducted with shoulder closures on I-95. Traffic may be reduced to one lane during allowable times. I-95 and Trafton Road will be closed for two nights from 10:00 p.m. to 5:00 a.m. While those two nights have yet to be determined, variable message boards will alert drivers in advance. All work on other roads will be accomplished with alternating one-way traffic assisted by flaggers.

It is anticipated all work will be completed by the end of June, 2017.
