Due to a partial collapse of the headwall/wingwall, the
City of Anchorage needed to replace a historic bridge that
dated back to the 1800s but wanted to keep its aesthetic
appearance intact. The city elected to use a CON/SPAN
®
structure because it most closely resembled the original
bridge and could be installed quickly to minimize road
closure.
In order for the stone facing to be kept in the exact
alignment as the original bridge, RAM Engineering
dismantled the remaining portion of the headwall stone
by stone, numbering each individual rock. After the
precast arches were installed, the crews worked to reface
the stone wall. Due to the weight of the stones, only one
row could be set per day.
“Through using the CON/SPAN precast bridge, the City was
able to minimize road closure, disruption to our residents,
and construction time while restoring the original historic
look of the bridge,” said W. Thomas Hewitt, Mayor of
Anchorage. “The new bridge resembles the historic look
of the stone bridge designed by Mr. Shallcross in the late
1800s. We are very pleased with the results.”
The original bridge was one of six constructed under the supervision of Mr. Jacob Shallcross,
Chairman of the Town Board, at that time. The bridges were part of his efforts to make the town a
beautiful garden spot.
