Grist Mill Bridge Opens with New Composite Beams System

摘要

In early 2021, AIT Bridges (Brewer, Maine, USA) announced that-in conjunction with the Maine Department of Transportation (MaineDOT) (Augusta, Maine, USA)-the replacement of Hamp-den's Grist Mill Bridge is complete, making the revamped road open to traffic. AIT Bridges is a division of Advanced Infrastructure Technologies (AIT), which designs and supplies composite bridge systems and related structural components. The former span of the Grist Mill Bridge was constructed in 1950, and it was comprised of three bridges built one on top of the other. However, the bridge had suffered from concrete deterioration, owing to years of exposure to the elements along with the use of deicing chemicals to combat Maine's harsh winter climate. The bridge spans over the Souadabscook Stream, which is an environmentally sensitive tributary of the Penobscot River.
