Contractor JCI Bridge Group erected a dozen temporary steel piers in clusters of four, braced and tied together, under each of the three box girders.

“The piers were fabricated from 30-inch diameter, 7/8-inch wall steel pipe, filled with sand” says Carl Tungate, P.E. of JCI adding, “The 54-foot tall piers sat on sill beams on the old footers.”
