The US 1 corridor is located in northeastern Wake and southwestern Franklin Counties, between I-540 in Raleigh and the northern intersection of US 1/US 1A (North Main Street) in Franklin County, a length of approximately 14 miles.

The corridor study area is in the Triangle metropolitan area of Raleigh, Durham, and Chapel Hill and is an important corridor in the north-south movement of people and goods in the region. The North Carolina Department of Transportation has designated US 1 as a Strategic Highway Corridor, as the facility connects the Raleigh area to Henderson and I-85. Due to increasing developmental pressures and the existing traffic congestion along portions of US 1 within the study area, the Capital Area Metropolitan Planning Organization (Capital Area MPO) along with other study sponsors has established the need to develop a comprehensive multimodal transportation plan for the corridor.

The purpose for conducting Study is to address two critical transportation needs:

  • To meet the growing travel demand
  • To improve safety

Current travel demand on the route meets or exceeds its capacity for the section of US 1 south of US 1A (South Main Street) in Wake County. Further adding to the congested travel conditions along this corridor, is the high percentage of trucks (between 8 and 14%) using the facility. By the planning year of 2030, traffic volumes along the study corridor are anticipated to exceed the current four-lane roadway's capacity. In addition, the crash rate for the study corridor exceeds the statewide average for over half of its length. The combination of high traffic volumes and high crash rates makes the US 1 corridor a good candidate for improvements.

The US 1 Corridor Study will develop an integrated transportation plan that provides for a high level of mobility as well as encouraging well-planned and sustainable growth along this corridor. An important goal of the study is to determine the right-of-way needed for implementation of the proposed improvements along the US 1 corridor before encroaching development makes multimodal improvements infeasible.

Corridor Description

The US 1 Corridor serves multiple travel purposes:

  • US 1 accommodates interstate travel, linking Raleigh with I-85 to the north.
  • US 1 connects downtown Raleigh with its northeastern suburban areas, including the Towns of Wake Forest and Youngsville, and unincorporated Wake and Franklin Counties.
  • This route will continue to become even more critical in providing regional connectivity when the eastern extension of I-540 is completed.
  • This section of US 1 serves as a local circulation route for north-south travel within the study area because the secondary road system is not complete.

Within the study area, US 1 is a primarily a four-lane principal arterial with 13 signalized intersections and over 100 driveways connecting to its main travel lanes. This high-speed arterial roadway passes through areas of rapid commercial and residential suburban growth, which have primarily located around existing interchanges and signalized intersections. Rapid development is anticipated along the entire corridor, so it is important to evaluate access management policies and future land use plans for the area.

Study Objectives

The US 1 Corridor Study is being conducted to achieve the following objectives:

  • To develop a clear vision of the transportation roles of the US 1 corridor with respect to mobility.
  • To formulate a multimodal transportation plan that incorporates highway, transit, pedestrian, and bicycle travel modes and complements the area's current and future development patterns.
  • To analyze the physical layout and number of general purpose and special-use travel lanes that are needed to serve the US 1 corridor travel demand in 2030. Right-of-way requirements for the proposed improvements will be evaluated and access management measures will be considered.
  • To consider community character and potential impacts throughout the planning process.
  • To determine changes in the access patterns within the US 1 corridor that could encourage better multimodal cohesion and connectivity in the study area and to reduce crashes along the corridor.
  • To ensure a positive influence on the surrounding community, neighborhood input and community involvement will play a critical role in the public involvement program.

The primary product of the study will be a coordinated multimodal transportation plan for the study corridor which addresses these objectives. The Capital Area MPO is managing the study through an interagency agreement between the City of Raleigh, NCDOT, the Town of Wake Forest, and the Triangle Transit Authority (TTA).

Workshop #1 Presentation

Workshop #1Comments

Two public meetings have been held for the study. The first public workshop was held on Tuesday, March 14, 2006 and the second on Thursday, July 27, 2006. Both workshops took place at the Living Word Family Church in Wake Forest.

The purpose of the first public workshop was to educate the public, elected officials, and other interested parties on the corridor, corridor planning principles, and the issues involved in developing integrated transportation and land use plans. The desired end product of the meeting was to establish a basis of knowledge among persons whose decisions will impact the corridor and to ascertain the desires of the public that uses the corridor.

The purpose of the second workshop was to present the alternative that received the most positive feedback during the first workshop; and address how that alternative can be enhanced through access management, aesthetics, multimodal accessibility, and compatible land use planning. Community input was solicited in the following aspects of highway design:

  • The application of frontage roads along the corridor
  • Landscaping within and along the corridor that will provide an attractive "gateway" into the region


Two newsletters will developed as a part of the study. These newsletters will provide information on the purpose and need of the study and what the study will entail. The second newsletter will be prepared prior to the second public workshop and will be in a format suitable for promoting the proposed plan. Newsletters are mailed to property owners within 1,000 feet of the US 1 Corridor.

Interstate 394 Business Impact Study

A corridor similar in nature to US 1 was recently upgraded to an interstate facility in Minneapolis, MN. This route, Interstate 394 (formerly US 12), is primarily a commuter route between downtown Minneapolis and the western suburbs. In its prior life, US 12 functioned as a combination of an expressway and boulevard with multiple traffic signals and driveway connections. The Center for Transportation Research and Education at Iowa State University recently completed a study describing the impacts of the improvements, particularly in regard to the business community.

Alternate III Example with One Way Frontage Roads

A Study Oversight Team (i.e., Steering Committee) has been created to provide guidance and oversight to the study. Team members will include representatives from the Capital Area MPO, Kerr-Tar RPO, City of Raleigh, Town of Wake Forest, Town of Youngsville, Franklin County, Wake County, TTA, and NCDOT. The Study Oversight Team will review the consultant's work, give direction and input, and monitor the project study as it takes place. The consultant may be asked to attend one or more of these meetings.

The Study Oversight Team will keep officials of the Capital Area MPO and Kerr-Tar RPO Transportation Advisory Committees apprised of progress throughout the duration of the contract by giving up-to-date presentations. The consultant may also be asked to attend one or more of the Transportation Advisory Committee meetings for the Capital Area MPO and Kerr-Tar RPO.

The study process will begin by clearly defining multi-modal transportation alternatives so that a unified vision of community design and infrastructure, land development changes and transportation improvements within the US 1 study corridor can be developed.

The US 1 Corridor Study Oversight Team will be the guiding force for this project. These members will determine land use and transportation improvement options for the US 1 corridor that should be advanced for further study.

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.
