Over-Under-Over
that someday we would make the trip to Williamsburg using the long bridge instead of the ferry. Year after year I could see the progress ~ more sticks in the water, concrete beams placed across
some of his buddies at the Vienna power plant. He told me this would be one of the longest bridges in the world when it was finished, and
Each trestle bent (bridge support) consists of three pilings and a horizontal concrete cap. The concrete pilings, up to 172 feet in length, were driven into the floor of the Bay, and then the cap was added to complete the bent. Four pre-cast roadway deck sections, 75 feet in length and shaped like double Ts when viewed from the end ( TT ), were then placed between pairs of bents to complete each trestle span. After all the spans were in place, the concrete decks were paved with asphalt to complete each of the trestles.
