Project Background

The U.S. 70 (future I-42) Corridor project between I-40 in southeastern Garner and Morehead City represents a significant undertaking involving multiple counties, particularly highway Divisions 4 and 2, which are overseeing various projects to upgrade segments of this corridor to interstate standards. By improving the movement of both people and goods along U.S. 70, this initiative seeks to enhance overall connectivity and stimulate economic growth in the region. The establishment of Interstate 42 will provide a more efficient and reliable transportation route, benefiting both local communities and the broader national transportation network, as well as improving safety and regional mobility and supporting economic development

Purpose and Need for the Project

In the spring of 2022, the USDOT informed state highway officials it had authorized NCDOT to sign a 10-mile segment of U.S. 70 near Clayton as Interstate 42. Before this change can be implemented, NCDOT will need to redesignate N.C. 42 in the same vicinity to avoid confusion with the drivers, and also redesignate U.S. 70 Business in the Clayton area as simply U.S. 70. 

Sections of roadway to be signed as U.S. 70:

A:     I-40/U.S. 70 in southeast Garner to Clayton Municipal Limits (approximately 5.8 miles)

B:     Through Clayton: Clayton Municipal Limits to Clayton Municipal Limits (approximately 3.3 miles)  

C.     Clayton Municipal Limits to U.S. 70/U.S. 70 business (approximately 2.8 miles) 


To avoid potential confusion for travelers, a portion of N.C. 42 will also be resigned.  N.C. 42 between N.C. 50 and current U.S. 70 Business will no longer be signed as N.C. 42.  Addresses along the area will change to reflect the following: 

Existing N.C. 42 between newly designated I-42 and current US. 70 Business will have its N.C. 42 designation removed.  It will remain signed as Lombard Street.

Sections of roadway to be signed as N.C. 36

A.     Existing N.C. 42 between N.C. 50 and I-40 

B:     Existing N.C. 42 between I-40 and newly designated I-42 (currently U.S. 70) 

C:     Newly designated I-42 between N.C. 42 and Ranch Road (S.R. 1560) 

D:     Existing Ranch Road between I-42 and current U.S. 70 Business 

Maps of these changes are shown below.
