Alden-Crittenden Road is a busy truck route and the bridge is located in close proximity to the village center, the local fire hall and the Alden Central school grounds. When the bridge needed to be replaced, the Erie County Department of Public Works (ECDPW) needed to minimize the time the bridge was out-of- service during construction because of the 5-mile off-site detour route.
“The existing bridge was built in 1932 and was in very poor condition” stated Wayne Scibor P.E., ECDPW’s Supervisor of Engineering. “We needed an installation that would minimize the disruption to the adjacent school and the local emergency services – that’s where Contech came in”
Watts Architecture & Engineering reviewed several bridge types with the ECDPW and they determined that a three-sided structure was the best solution and chose a 32’ x 8’ CON/SPAN® Bridge System. The three-sided precast structure offered a number of advantages over alternative solutions, including: lower initial cost, high- quality precast concrete, smooth underside with ample clearance and an attractive appearance.
Nine precast concrete CON/SPAN® arch units were installed and placed on cast-in-place concrete footings founded on steel H-piles. Precast headwalls and wingwalls were also included in the design.
The use of precast bridge components provided the ECDPW with an efficiently constructed bridge that saved both time and money because it was constructed in less than three months. In addition, the structure will last and perform well for years to come.
“The speed in which the CON/SPAN structure can be installed is very impressive” added Phillip Galbo, P.E., Principal of Watts Architecture & Engineering. “They set all of the arch units and the headwalls in one day”
The reconstruction of the Alden-Crittenden Road Bridge over Spring Creek was completed in Fall 2010, on time and within budget.
