On Tuesday, April 5, 2016 the City of Grand Prairie approved a construction contract with Jackson Construction in the total amount of $2,722,734.00 for I-30 Frontage Road Utility Relocations from NW 7th Street to Belt Line Road. This contract amount included the bid of $2,593,080.00 and a 5 percent contract contingency of $129,654.00
This project was identified in order for the Texas Department of Transportation to construct a three lane service road for eastbound traffic in the area between NW 7th Street and Belt Line Road and includes construction of 2,947 linear feet of 24-inch water line, 717 linear feet of 30-inch water line, 30 linear feet of 36-inch water line, various water line appurtenances such as valves, 616 linear feet of 8-inch PVC sanitary sewer, 51 linear feet of 12-inch PVC sanitary sewer, 142 linear feet of 27-inch PVC sanitary sewer, 6 new sanitary sewer manholes, and 83,400 cubic yards of general site excavation to lower the hill where a billboard is presently located adjacent to Interstate 30.

Therefore, in order to keep the City’s utility relocations on schedule, it was recommended by the contractor and engineer to bore this short section under the existing guy wire support.
