NCDOT to Construct U.S. 220/N.C. 68 Connector (Future I-73) in Greensboro

RALEIGH-Crews will soon begin installing signs and moving dirt in Greensboro as construction of the U.S. 220/N.C. 68 Connector (Future I-73) gets underway.

In April, the N.C. Department of Transportation awarded a $176.6 million contract to the design-build Team of Flatiron Constructors, Inc./Blythe Development Company -A Joint Venture/RK&K, LLP. Construction is scheduled to get underway late this month, with a completion date of April 25, 2017.

The 9.4-mile, four-lane future interstate will extend from Bryan Boulevard to just south of U.S. 220 near the Haw River. A separate project already under construction will complete the connection to U.S. 220 in Rockingham County.

The project will include interchanges at N.C. 68 and N.C. 150, as well as bridges over Reedy Fork Creek. It will also include construction of a taxiway bridge at Piedmont Triad International Airport that crosses the future I-73. The taxiway bridge will spur development by providing runway access to approximately 400 acres of developable PTIA-owned land on the north side of the future I-73.

In the planning stages since the mid 1990's, this project is Rockingham County's top priority transportation improvement project. It is among the top priority projects for Guilford County as well. The project was originally scheduled to begin construction in 2016, but NCDOT worked with Greensboro's Metropolitan Planning Organization and local and state elected officials to speed construction of the taxiway and a section of the connector. Construction on the taxiway bridge is expected to begin in November and is scheduled to be completed by August 2016.

To reduce the overall construction cost, deliver the project more quickly, and reduce impacts to motorists and the environment, the Flatiron/Blythe Development/RK&K Design-Build Team will:

  • Complete the taxiway bridge in August 2016, four months earlier than required. Construction of Future I-73 is scheduled to be completed in April 2017, nearly seven months earlier than required;
  • Accelerate the construction schedule, eliminating the need to provide a temporary operational I-73 roadway connection between Bryan Boulevard and North Regional Road;
  • Shift the horizontal alignment of the future I-73 in proximity to the taxiway bridge, reducing the required excavation depth by 8-10 feet and shortening the taxiway bridge by approximately 20 feet;
  • Shift the horizontal alignment of the flyover ramp at the N.C. 68 interchange to the west, eliminating the need to construct a 915-foot long, 25-foot high retaining wall;
  • Implement two additional wetland mitigation sites, providing approximately 1.5 acres of additional non-riparian wetland restoration.
  • Extend the term of the required project guarantee for an additional nine years, agreeing to stand by its work for a total of 10 years;
