Route 1 northbound and southbound lanes were closed for about an hour after the crash Thursday evening

A Smyrna man was seriously injured in a two-vehicle collision Thursday evening near Townsend.

At 7:05 p.m., Thomas Baker Jr., 34, of Smyrna, was driving a 2004 Chevrolet Trailblazer in the left lane on southbound Route 1, north of New Discovery Road near Townsend, said Delaware State Police.

Baker attempted to enter the right lane and the right side of his vehicle struck a 2014 Hyundai Sonata, police said.

Baker's vehicle then veered to the left and entered the center median, where it overturned several times before coming to rest on its passenger side on northbound Route 1.

Baker, who was properly restrained, was trapped until he could be extricated by emergency personnel. Townsend and Odessa fire companies responded to help.

He was treated at the scene by New Castle County paramedics and flown by state police helicopter to Christiana Hospital where he was treated for serious injuries, police said.

According to the paramedics, fire company personnel worked for 20 minutes to free Baker, the only person in the vehicle. He was evaluated for a possible head injury before being flown to the hospital and was stable at the time of transport, paramedics said.

No one else was injured, police said.

Baker was cited for inattentive driving and several other license and registration violations, police said.

Route 1 northbound and southbound were closed in the area for about an hour as the crashed was investigated and cleared.
