Bridge

Repair crews work on Interstate 93 southbound in Concord after a truck with its dump body lifted upward struck an overpass at Exit 17 on Thursday.

CONCORD — A dump truck driver was cited for negligent driving after his truck, lifted in the upward position, struck an overpass at Exit 17 on Interstate 93 south Thursday.

Traffic was detoured for more than six hours and three people went to the hospital.

The truck was driving under the Hoit Road (Route 4) bridge, when the dump body struck the bridge, “scattering debris in the roadway,” State Police said.

The truck’s driver, Joseph Brady, 57, of Conway, was issued a summons for negligent driving. Police don’t know why the truck was in the lifted position.

Interstate southbound lanes at Exit 17 in Concord reopened to traffic in the early afternoon, according to a tweet from state Department of Transportation just before 1 p.m. The Route 4 westbound bridge over I-93 also reopened.

Three other vehicles were involved in the accident, reported after 6 a.m. Three drivers were taken to Concord Hospital for precautionary reasons with no serious injuries reported, police said.

State bridge maintenance crews worked to repair the damage to the overpass.
