U.S. 220/N.C. 68 Connector (Future I-73)
The N.C. 68 Connector portion of the project includes interchanges at N.C. 68 and N.C. 150, as well as bridges over Reedy Fork Creek.
This section, was combined with the Future I-73 and taxiway bridge to speed the construction of the taxiway bridge over I-73. In the planning stages since the mid-1990s, this project is Rockingham County’s top priority transportation improvement project. It is among the top priority projects for Guilford County as well.
Future I-73 and Taxiway Bridge
This section runs from the Joseph M. Bryan Boulevard/Airport Parkway interchange, near PTIA, to N.C. 68. All lanes are expected to open to traffic in July 2017.
Work included building a taxiway bridge at the airport that crosses I-73. The taxiway bridge is expected to spur development by providing runway access to approximately 800 acres total – 500 acres north of the taxiway and 300 acres to the south.
To speed construction of the taxiway bridge – which was completed in May 2017 – this section was combined with the U.S. 220/N.C. 68 Connector section into a single design-build contract.
To reduce the overall construction cost and deliver the project more quickly, the sections are being built under what's called a "design-build contract," which allows for the design, environmental permitting, right-of-way acquisition, utility relocation and construction to take place at the same time under one contract.
This method also reduces overall construction time, helps NCDOT avoid cost inflation, allows the contractor to make innovations that save taxpayers money, lessens environmental impact and alleviates driving delays for motorists.
Under a $176.5 million contract, the Flatiron/Blythe Development/RK&K design-build team is expected to complete the taxiway bridge in May 2017. The construction on the future I-73, including both individual projects noted above, is scheduled to be completed in May 2017, nearly six months earlier than required.
Project Guarantee Extension
NCDOT required a one-year guarantee on the construction for this project. The design-build team added nine years to that guarantee, agreeing to stand by its work 10 years.
