One man was killed and another seriously injured Friday afternoon in a car crash that closed a major street for several hours.

Thetwo men were installing high-speed internet cable when they were struck by a car on St. Mary's Road near Kingston Row.

"I heard a crash and a screech, and I turned around and two guys were in the air," said Monique Girardin, who lives directly in front of the crash site on St. Mary's Road and saw the accident while collecting her mail.

"The car came to a halt here and the two guys landed, and people that were passersby got out of their vehicles, and everybody just got on their phones with 911," she said.

"It all happened so fast. I ran over there and asked if there was anything I could do. I brought over blankets. It was all pretty surreal."

Police said a 44-year-old man had been killed, while a 24-year-old man was in hospital in critical condition.

A white Camaro with a missing back wheel and smashed windshield rested at an angle in the middle of the road Friday afternoon. A Honda minivan was also damaged in the collision.

The condition of the drivers or others in thevehiclesis not yet known.

It's believed the two men struckare employees of Blais Underground, whichhad been installing cable in the area all week. No one from the company could be reached for comment.

St. Mary's was closed in both directions at Kingston Row while police and fire crews worked at the scene.
