This New Hampshire bridge takes advantage of the increased load carrying capacity of HPC. The number of girders was reduced from seven to five by using HPC.

The deck concrete here was specified to have no more than 1,000 coulombs when tested using ASTM C 1202 . The deck has been reported as "crack free."

For more information on this bridge, please see: Waszczuk, Christopher, "Crack Free HPC Bridge Deck -- New Hampshire's Experience," HPC Bridge Views, No. 4, July-August, 1999, pp. 2-3.
