Traffic along Route 1 from Orland to Thomaston moved slowly on March 26 for those drivers encountering the transport of two large concrete beams bound for a South Thomaston bridge project.

The beams, measuring 120 feet in length and weighing 120,000 pounds, were cast in St. John, New Brunswick, and are to be used in the $2.1 million reconstruction of the Spruce Head Bridge by Reed and Reed Inc. They were carried down the coast on large trailers owned and operated by Mills Heavy Hauling, based in Halifax, Nova Scotia.

Mills Heavy Hauling is accustomed to transporting large, heavy and awkward items aboard its trailers. The concrete beams are the first of two loads; on Monday, March 29, the trucks will return with two more concrete beams bound for the Spruce Head Bridge, said Jeff Mills, general manager of Mills Heavy Hauling.

The first load of beams left St. John and arrived at the U.S. border in Calais on March 23. After going through Customs, the trucks carried the beams down the coast. An error in paperwork, however, sent the trucks down to Sedgwick, Deer Isle and eventually Stonington and the wrong job site.

That presented a three-day delivery delay to the right job site in South Thomaston. Mills and the bridge construction companies had to straighten out permits with U.S. Customs, and also had to wait several days before Maine state troopers could muster the four cars needed to help with traffic control.

Once the beams were delivered March 26, Mills expected the crew to head back to St. John.

“With any luck they’ll unload tonight, and go back to St. John and get two more,” he said.
