A spokeswoman for Eastern Maine Medical Center said James Westerdahl, 75, of Littleton died Friday afternoon.
He was southbound in his 1999 GMC truck about 3:15 p.m. Wednesday when reportedly a tire blew out on the extended cab vehicle.
Westerdahl lost control and swerved into the northbound lane, directly into the path of an oncoming tractor-trailer truck driven by James Sprague, 57, of Nobleboro.
