Treat Williams, a veteran actor who starred in the TV dramas "Blue Bloods" and "Everwood," died Monday night as the result of a motorcycle accident in Vermont, his longtime agent, Barry McPherson, told CNN.

He was 71.

While local authorities have not yet named Williams, Jacob Gribble, the fire chief for Dorset, Vermont, told People the crash happened on Monday around 5 p.m. EST on Route 30 by Long Trail Auto near Dorset. Investigators, according to Gribble, believe the driver of a vehicle was turning and did not see the motorcycle driven by Williams when the accident occurred. CNN has reached out to Gribble for comment.

Born Richard Treat Williams in Rowayton, Connecticut, he studied theater in college and moved to New York shortly after graduating. There, he nabbed the understudy role to John Travola in "Grease" and later replaced him as Danny Zuko.

Williams' versatile screen career included an early role in director Milos Forman's adaptation of the musical "Hair" in 1979, followed by a starring vehicle with another A-list director, Sidney Lumet, in the gritty undercover crime drama "Prince of the City" two years later.

While Williams appeared destined for major stardom, his next several movies didn't equal that early promise, though he continued to work steadily, including in a TV movie remake of "A Streetcar Named Desire" and additional TV movies in which he played boxer Jack Dempsey and FBI chief J. Edgar Hoover.

In the '90s, the actor segued into different kind of roles, playing the villain in the pulp-comic adaptation "The Phantom" and super-agent Michael Ovitz in the HBO movie based on the book "The Late Shift," about "The Tonight Show" succession battle between Jay Leno and David Letterman. He earned leading action star status in 1998's B-movie "Deep Rising," about a killer sea monster, starring opposite Famke Janssen, Wes Studi and Djimon Hounsou.

Williams subsequently found new success in television, starring in the CW series "Everwood" for four seasons in the aughts and a more recent stint on "Chicago Fire." Last year, he co-starred in the HBO miniseries "We Own This City," producer David Simon's chronicle of corruption and internal politics in the Baltimore police department.
