Two piles of broken roof trusses lie on the ground next to Charlotte’s new town garage. The trusses were blown down when heavy winds came up around 4 p.m. Friday. Men were working at the time. It was amazing that no one was injured or killed, said John Masterson of Masterson Excavation. Town administrator Dean Bloch said the damage won’t add anything to the town’s cost. That will be borne by the contractor or its insurance. Bloch said the destruction may add two weeks to the completion date.
