Project Overview and Purpose

The N.C. Department of Transportation has built a 9.4-mile, four-lane roadway – 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 involved building a taxiway bridge at Piedmont Triad International Airport that crosses over I-73.

At the northern end, 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)
  • I-73 and Taxiway Bridge at PTIA (I-5110)

Project Highlights

U.S. 220/N.C. 68 Connector (I-73)

The N.C. 68 Connector portion of the project – which opened to traffic in May 2017 – includes interchanges at N.C. 68 and N.C. 150, as well as bridges over Reedy Fork Creek.

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.

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.

Design-Build Contract

To reduce the overall construction cost and deliver the project more quickly, the sections are being built under 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 completed the taxiway bridge in May 2017. The construction of I-73 is scheduled to be completed in July 2017, 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.

Resources for Local Property Owners

Although the N.C. Department of Transportation works to minimize the number of homes and businesses displaced by a road project, it is inevitable, in many cases, that a certain amount of private property is needed. The following information explains right of way acquisition and answers questions about the process.
