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."
