The state Department of Transportation is warning drivers about Manchester area construction projects that will cause traffic disruptions on Interstate 93 in the coming weeks and months.

DOT will be closing the Exit 8 off-ramp to Wellington Road on I-93 northbound starting on May 8, and a detour will be in place for three months. The closure is part of a project to improve the northbound bridges over Wellington Road and Stevens Pond, the agency said in a news release.
