NEWPORT, Del. (AP) — A fix costing nearly half a million dollars will finally begin this summer on a $5 million bridge that was built six inches too low.
Five years after Delaware transportation officials discovered the mistake, they’ve hired a new construction firm to raise the bridge high enough so that trains carrying two stacked containers can pass underneath. Those trains need at least 21 feet, 6 inches of clearance.
The Delaware Department of Transportation spent more than $5 million in 2011 to accommodate these trains by rebuilding the overpass, reported The News Journal (http://delonline.us/1OJzwdj ). They think they know what caused the error: surveyors mistakenly measured the clearance from the ground up, rather than from the top of the track’s steel rails, said Barry Benton, DelDOT’s state bridge engineer.
