An unidentified driver was hospitalized after the car he was driving left wreckage strewn along Hammond Street in downtown Bangor on Monday.

A careening car jumped an empty sidewalk and left a downtown street strewn with wreckage Monday, but only one person, the driver, was injured, police said.

The white sedan flew around the corner at Giacomo’s before hitting the sidewalk and accelerating up Hammond Street. It sideswiped two cars and took out a light pole before coming to rest at State and Exchange streets.

Witness Kimberly Colavito, a front-desk worker at Thomas School of Dance on State Street, said she was stunned at how fast the car was going.

“No one was out there, probably because it was raining,” Colavito said Monday. “Usually there are people out there.”

The driver, who walked away from the crash, had minor injuries, Bangor police Lt. Catherine Rumsey said.

Police had part of State Street blocked as their investigation continued. Rumsey asked motorists to use alternate travel routes until the light pole was replaced.

Colavito said the driver was conscious and alert when an ambulance took him away. She saw him standing on the sidewalk talking with passers-by, she said.
