Structural Plate Crossing Bends with Meandering Creek to Save Substantial Time, Money and Environmental Impact
August 25th, 2009
Big R Bridge recently completed a contract to manufacture a 420’ Bolt-A-Plate bottomless crossing with seven elbows in it to follow the path of a winding creek under a major new road in Canton, GA.
By staying outside of the creek banks and not disturbing the waterway, we were able to save the owner thousands of dollars in construction costs and environmental impact fees, over a traditional bridge and concrete structure. Several of these options were considered, however the Bolt-A-Plate option became the obvious choice being the most economical and environmentally-friendly.
Commerce Boulevard is a new road serving a commercial area, a hospital and a future residential area. The four-lane parkway with sidewalks has a 40’ cover depth, which added to the culvert length requirements. The structure had a span of 20’ and a rise of 10’ with 2:1 beveled-ends. The project was completed in 6 ½ weeks with 4 weeks for rock excavation and forming/pouring of approximately 500 cubic yards of concrete. We prefabricated the elbows at our plant, allowing the contractor to assemble the entire structure in only 1 ½ weeks. The final week was for the engineered backfill zone.
The overall site and roadway was contracted and managed by N.J. Wilbanks Contractor, Inc. from Canton, GA. The subcontractor for the structure, and Big R Bridge's client, was North Georgia Concrete Inc, of Dahlonega. Past successes on similar projects were instrumental in helping us secure this project.
Strong, economical, lightweight and made from recycled steel, Bolt-A-Plate is ideal for new site developments, county stream crossings, as well as urban rehabilitations. It comes in Standard, Low and High Profile Arches, Pear Shapes, Round Pipes, Pipe-Arches and Ellipticals.
