“ITD will place 10 steel girders over the two nights. Each girder is 136 feet long and weighs approximately 115,670 pounds,” said Alex Deduck, ITD Design/Construction Engineer.  “This is no small operation and we appreciate the patience of the traveling public during the detour.”

ITD is replacing the Karcher Overpass to accommodate additional lanes on I-84. Construction to widen I-84 will begin later this summer.
