A two-car crash just before 2 p.m. at the intersection of Main Street and Route 6 sent at least one person to the hospital Wednesday.

How many people were in each vehicle and the extent of their injuries could not immediately be confirmed.

"It was a big bang," said Cindy Parola, who witnessed the accident. "Immediately, a pile of hazardous waste was on the ground."

Traffic was stalled in all directions as Wareham Police directed drivers around the scene and workers cleaned the fluids that spilled onto the ground.

"All I saw were fenders going everywhere," Parola said.
