HEB Engineers in North Conway was retained by the Town of Clarksville, New Hampshire to design a replacement bridge on Dead Water Stream that discharges into Lake Francis. The new SUPER- SPAN arch bridge would replace an old steel stringer timber deck bridge built around 1930 that was placed on NHDOT’s “Red List” of deficient bridges.

The project was engineered and bid as a 52’ span x 22’ rise SUPER-SPAN arch or precast concrete BEBO® arch. The low bidder, Winterset, Inc. decided to use the galvanized steel SUPER-SPAN with cast-in-place concrete headwalls and force protection. “The SUPER-SPAN culvert was chosen for ease of construction, the most economical solution and ease of permitting, since minimal work needed to be done in the Dead Water Stream” said Ed Bergeron of HEB Engineers.

During installation, the existing road was relocated to maintain traffic flow during construction. The structure was completed during the summer under the state bridge aid program.
