The initial study of the planning and development of extending N.C. 55 to Judd Parkway in Fuquay Varina advised converting intersections of N.C. 55/ N.C. 42/U.S.-401 to an interchange. However, in a study completed by the Capital Area Metropolitan Planning Organization in September 2015, concluded that the area beyond the immediate vicinity of the intersection be studied to comprehensively address congestion in the roadway network.
Addressing delays and congestion solely at the intersections of U.S. 401 at N.C. 42/N.C. 55 and N.C. 55 at N.C. 42 will only shift the deficient traffic operations to other parts of the network.
In February 2020, the N.C. Department of Transportation, the Federal Highway Administration, the U.S. Army Corps of Engineers and the N.C. Division of Water Resources reached an agreement to move forward with three alternatives for further study.
