Emergency crews responded to the area of Puopolo Park on Commercial Street at about 11:30 a.m. The boom of the crane went through a nearby truck and came to a rest on a baseball field.
The crane operator and a passerby who may have been injured trying to move away from the collapse were both transported for evaluation. Both are expected to be okay.
The owner of the parked truck said it could have been a lot worse.
"What can you think? Thank God nobody got killed," he said.
Clean Harbors assisted with the cleanup due to a fuel spill caused by the collapse. About 200 gallons of liquid leaked from the crane. Fire officials say the liquid is a combination of diesel fuel and hydraulic fluid. HazMat crews are treating the area to prevent toxins from seeping into catch basins.Commercial Street from Hanover to North Washington was closed through the evening commute to pedestrian and vehicular traffic.
Boston police were investigating, as well as the Occupational Safety and Health Administration.
