I-5110 / R-2413A & B (Future I-73)

Project Overview and Purpose

The N.C. Department of Transportation is building a 9.4-mile, four-lane roadway – which will be designated as I-73 – that begins at the Joseph M. Bryan Boulevard/Airport Parkway interchange in Greensboro, crosses over N.C. 68 and ends south of U.S. 220 near the Haw River. Work also involves building a taxiway bridge at Piedmont Triad International Airport (PTIA) that will cross over the future I-73.

At the northern end, the future I-73 will connect with another U.S. 220 project, which is currently under construction and will extend to N.C. 68 in Rockingham County. The interstate will help connect drivers from Rockingham County and other areas north to Greensboro and PTIA.

This project consists of two sections:

  • U.S. 220/N.C. 68 Connector (R-2413AB)
  • Future I-73 and Taxiway Bridge at PTIA (I-5110)

Project Highlights

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 will run from the Joseph M. Bryan Boulevard/Airport Parkway interchange, near PTIA, to N.C. 68.

Work includes building a taxiway bridge at the airport that crosses the future I-73. The taxiway bridge is expected to spur development by providing runway access to approximately 400 acres of land on the north side of the future I-73.

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.

Project History

Grading activities at the taxiway bridge are completed and the bridge currently under construction. The bridge is scheduled for completion in May 2017.

Resources for Local Property Owners

In many cases, it is inevitable that a certain amount of private property must be acquired. The displacement of homes and businesses is minimized to the extent practicable. The following brochures will answer questions about this process.
