The Maine State Police say one person has been seriously injured in an accident between a dump truck and a vehicle that has tied up traffic on I-95 in Augusta.

Maine Department of Public Safety spokesman Steve McCausland said that a significant traffic backup in the northbound lanes in Augusta will likely continue for much of the afternoon.

McCausland said troopers said a car slammed into the rear of the truck, as it was slowed in traffic. The crash took place at mile marker 113, just beyond Augusta’s third exit, McCausland said. Northbound traffic is advised to take exits 109 or 112 to avoid the crash site and to seek alternative routes north.

McCausland said the breakdown lane at the crash site is now open, but traffic is moving at a crawl. Northbound traffic on the Interstate in Augusta should seek alternate routes to avoid the crash site, he said. The Lifeflight helicopter was dispatched to fly the injured person to either of the hospitals in Lewiston or Bangor.
