An Andover man was killed in a single-car crash on Interstate 93 in Andover on Saturday morning, State Police said.
Shannon Smith, 51, was driving a 2014 Cadillac CTS when he veered from the northbound left lane and struck a guardrail just south of Exit 45, according to a State Police statement.
He had sustained serious injuries by the time troopers arrived on scene around 12:10 a.m., said David Procopio, a State Police spokesman, in an e-mail.
Smith was taken to Lawrence General Hospital, where he was pronounced dead, State Police said.
The left lane was closed for about two-and-a-half hours, according to the statement.
The incident is under investigation.
