The truck crash on I-93 north in Dorchester delayed traffic for hours.

Southbound traffic on the Zakim Bridge was backed up as well, partly caused by the effects of the truck crash.

Southbound traffic on the Zakim Bridge was backed up as well, partly caused by the effects of the truck crash.

A dump truck crashed through a guardrail on Interstate 93 in Dorchester on Monday morning, jamming traffic for miles throughout the day, and spilling brake fluid into the bay, officials said.

The driver, who suffered minor injuries, had emerged from the water when firefighters arrived.

He was taken to Boston Medical Center “as a precaution,” Boston Fire Department spokesman Steve MacDonald said.

Firefighters responded to reports of the crash at 10:07 a.m. when the 15-ton truck carrying gravel and dirt slid down the embankment near the Dorchester Yacht Club. The vehicle was removed just after 5 p.m., said State Police.

Drivers experienced significant delays throughout the day due to lane closures and other trucks responding, police said.

“It’s been backed up since this morning,” said State Police Lieutenant Daniel Richard.

“We had a lot of trucks out there to deal with the crash and the environmental problem.”

One driver, who asked not to be named, said he spotted at least 30 law enforcement cars responding to the scene and clogging the highway.

“I can’t believe how many people are there,” he said. “You’d think the world was coming to an end.”

But by about 6:50 p.m., MacDonald said the lane was “completely repaired and completely reopened.”

MacDonald said he saw that one of the truck’s tires was “in pretty bad shape,” potentially indicating a mechanical failure on the vehicle.

Richard said police were continuing to investigate the cause of the crash, which was still unclear as of Monday night.

The Boston Fire Department and State Police, along with a Hazmat team and the Coast Guard, worked together to extract the truck and prevent further leaks.

Using cables connected by a State Police diver, three heavy-duty tow trucks helped pull the truck up the embankment, MacDonald said.

Responders drained the fuel tank and then got the truck back on the ground.

The remaining leaked fluid was removed from the water and the shoreline by Clean Harbors, an environmental cleanup provider.

“The water is really cold right now so there’s not a lot of damaged marine life to be expected,” said Scott Metzger, senior vice president at Clean Harbors.

Police placed an absorbent boom into the water to soak up any spilled fluids from the truck.

The truck, which belongs to the Mobile Excavating Corp., a Medway-based contractor, was carrying dirt and gravel, a company official said.
