85-385 Gateway

85-385 Gateway is utilizing a design-build contract which will require the successful bidder, Flatiron/Zachry Joint Venture, to design, obtain permits, acquire right-of-way, coordinate utility relocation, and construct the new interchange; all under the oversight of SCDOT and FHWA. This approach to improving infrastructure potentially saves time and money by encouraging innovative designs and construction practices. The Project’s scope involves creating a new interchange within the general footprint of the current interchange by staging construction of the new lanes, ramps, and bridges while maintaining traffic. There will also be improvements to Woodruff Road, Garlington Road, Miller Road, and Chrome Drive under this contract. Finally, construction of ten new bridge structures including two flyovers, rehabilitation of two existing bridge structures, and improvements to one existing substructure will occur to facilitate this new interchange system. The work being done on these roads and bridges will help alleviate traffic congestion along this entire corridor. The expected construction start date is late 2015 with anticipated substantial completion by late 2018.
