First responders rescued the driver of a box truck after it crashed off the Interstate 293 bridge in Manchester and into the Merrimack River on Wednesday.
Two northbound lanes at Exit 2 near Brown Avenue on I-293 were closed midday as police and fire responded to investigate the accident.
Travelers are urged to avoid the area.
Manchester firefighters launched rescue boats to reach the driver and bring him to shore, with initial reports the driver sustained non-life-threatening injuries, Manchester InkLink reported.
State Police said that up to six vehicles were involved in the accident. They identified the driver of the box truck as Dylan Pagan Rodrigeuz, 26, of Fall River, Mass.
A minor passenger in one of the vehicles suffered serious injuries, police said.
Rodriguez was not injured after his truck broke through the guardrail and fell about 50 feet into the river, police said. I-293 was down to one lane for multiple hours as crews worked to clear the scene and hoist the truck out of the river.
