Project Overview

The N.C. Department of Transportation proposes to convert three at-grade intersections on U.S. 421 and make other improvements in Randolph County near the Guilford County line.

Improvements include:

Conversion of at-grade intersection to interchange

  • Colonial Trading Path/Shiloh Road

  • Julian Airport Road (S.R. 2502)

  • Shiloh Road/Starmount Road (S.R. 2407) 

Closure of at-grade intersection

  • Browns Meadow Road (S.R. 2408) 

Intersection realignment 

  • Shiloh Road/Colonial Trading Path/US 421

  • Old Red Cross Road (S.R. 2403)/Shiloh Road

  • Old Red Cross Road/Harold Meadow Road (S.R. 2404).


The purpose of the U.S. 421 interchange project is to improve traffic operations and enhance safety within the study area by providing effective access to U.S. 421 from the local roadways.


Project History

In December 2021, the Greensboro-Randolph Megasite was chosen as the location for Toyota’s new $1.29 billion automotive battery manufacturing plant.  This plant will be named the Toyota Battery Manufacturing, North Carolina (TBMNC) and is expected to begin operation in 2025. The local road system will not be able to provide the necessary capacity and the desired access to function adequately. U.S. 421 serves as an important north-south facility for residents from several smaller cities and towns as access to Greensboro. The existing roadway network would not be able to accommodate a heavy increase in peak hour traffic. Upgrading the at-grade intersections to grade-separated interchanges will allow for these forthcoming increases in traffic volumes.

​The N.C. Department of Transportation builds roundabouts to improve safety for drivers,​ pedestrians and bicyclists. They also help reduce the congestion and backups more typical of traditional intersections with stop signs and traffic signals.  A driver generally enters the roundabout more quickly than if waiting at a traffic signal. In addition, the modern roundabout is much smaller than older traffic circles and requires vehicles to travel at lower speeds (15-20 mph), making them safer than traffic circles. Additionally, the slower speeds make it easier for a driver to find a gap of traffic inside the roundabout before safely entering it.​

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.
