Vermillion County, Indiana
Print Case Study
October 3, 2002
In June of 2002, a major storm completely washed a Vermillion County road bridge downstream. Shutting down the road for construction meant creating a 15-mile detour delay, and county officials determined a different, more permanent solution was needed. Due to the road’s importance for emergency vehicle access, it was critical to find a quick, economical solution to bridging the stream.
To rapidly replace the bridge, CPI and Contech proposed a design-build solution. The design included engineering and a method to oversee the bidding process. The replacement structure consisted of a 40’ span x 24’ wide Contech Steel Stringer bridge. The structure was hot-dipped galvanized, utilized an asphalt deck and had an attached guardrail system.
The abutments were placed on a reinforced concrete spread footing and were constructed with H-Beams and Contech’s Bridge Plank. This was an economical solution verses a full height cast-in-place concrete abutment. The Contech prefabricated, clear-span steel bridge meets AASHTO HS-25 demands for the heavier loads required by the mining industry and allows water, as well as debris and vegetation, to flow freely downstream.
