Pi-Girder placement underway
May 23, 2018
The first of 210 “pi-girders” are being placed for the new Pensacola Bay Bridge. Of all the components for the new bridge, these girders are the heaviest. Each Pi girder is 150-long and consists of two beams and a section of the multi-use path. The girders weigh approximately 202-tons, or 404,000-pounds.
They get their name because their ends resemble the Greek letter and mathematical symbol “Pi.” The girders will form the 10-foot wide multi-use paths for the east and westbound bridges.
They’re fabricated at the Bayou Chico casting yard and transported to the construction site by barge where one of the two big ringer-cranes lifts and places them on the trophy piers.
