At Herron Farm in Elkton, Maryland, the farmland was converted into an insurance auto auction site with an 80-acre vehicle storage yard and a 10,000 sf prefabricated metal building. Associated site improvements included stormwater management, erosion and sediment control, forest conservation, and roadway improvements including a bridge replacement to improve hydraulics through the existing streams. When an existing bridge crossing was deemed structurally deficient, a replacement was needed adjacent to its location.
After consulting with engineer Frederick Ward Associates (FWA), the project's owner, Greenspring Realty Partners, Inc. (GRP), decided that a 80' x 24' Big R Bridge® Rolled Girder was the best replacement option. Selecting a fully pre-fabricated structure over other options allowed for a rapid installation. Additionally, EXPRESS® Pedestal Foundations and Contech Anchor wingwalls were utilized to further expedite the installation. The foundations were installed in a week, while the Big R structure was installed in just one day.
In the end, the Big R structure was a great solution for the site, and GRP and FWA were pleased with the outcome.
“This bridge was the primary route in and out of the project which allowed for full scale development," concluded Tom Miner, PE, CCM, Vice President with FWA. "Making the bridge operational was critical for construction timing. The Big R product along with the Express Foundation helped create an easy and quick plug and play design to be integrated into the hydraulic modeling and roadway alignment."
