On Dec. 17, 2010, USA HDD Texas LLC, a division of Utility Services Authority, LLC (USA) of Belleville, Mich., began receiving the first of 15 semi tractor-trailers loaded with drill rod, reamers and support equipment into Beaumont, Texas, in preparation for one of Texas Department of Transportation’s (TxDOT) more unique projects.
The TxDOT is in the planning stages of rebuilding the Purple Heart Memorial Bridge, which extends across the Neches River, connecting Orange County and Jefferson County. However, before construction can begin, existing conduits containing utilities located on the bridge and directly under the proposed new foundations need to be rerouted to an area that will not be impacted by the approaching construction. The solution: to horizontally directional drill a 30-in. diameter steel casing 4,000 lf nearly 140 ft below the river bottom to serve as a carrier pipe for multiple conduits, which will house the relocated utilities. This is an area where Utility Services Authority LLC has a wealth of experience, especially in the eastern United States.
