Project Overview and Purpose

To improve safety and ease traffic congestion, the N.C. Department of Transportation and local leaders have proposed to add a median and limit left turns along two busy commercial corridors in Aberdeen and Southern Pines: U.S. 15-501 and U.S. 1.

Segments of the two highways now have four lanes with a two-way center turn lane, which NCDOT would eliminate through the use of a design called a Synchronized Street (also known as a Superstreet).

Crash history from October 2009 to December 2016 shows U.S. 1 and U.S. 15-501 exceed the statewide critical crash rate. Improvements to these two highways would not only improve safety but also reduce delays and plan for anticipated traffic growth in the area.

Project Highlights

The N.C. Department of Transportation has proposed to build a four-lane Synchronized Street (two lanes in each direction) – rather than the needed six-lane street (three lanes in each direction) – in Aberdeen and Southern Pines to improve conditions and accommodate traffic on sections of U.S. 15-501 and U.S. 1, as described below.

U.S. 15-501 from U.S. 1 to Brucewood Road (STIP Project U-5814)

A Synchronized Street would be built on a 1.3-mile segment of U.S. 15-501 from U.S. 1 to Brucewood Road. (View concept map)

Right of way acquisition is currently scheduled to begin in 2018, and construction is currently scheduled for 2020.

U.S. 1 (North Sandhills Boulevard) from Roseland Road to Old U.S. 1 (STIP Project U-5815)

Proposed work on U.S. 1 involves a 2.8-mile segment from Roseland Road to Old U.S. 1. Work would be divided into two phases, referred to as Section A and Section B. (View concept map)

  • Section A involves building a Synchronized Street on the southern section of U.S.1 from Roseland Road to Knight Street (0.6 miles).
  • Section B involves building a Synchronized Street on the northern section of U.S. 1 from Knight Street to Old U.S. 1 (2.2 miles). (View concept map) Work would also include minor improvements to the southern section of U.S. 1, including realigning Roseland Road at U.S. 1.

An alternate design at the U.S. 1/Old U.S. 1 intersection has also been developed. It adds a traffic signal at the existing free-flow merge from Old U.S. 1 onto U.S. 1 and enlarges the U-turn bulb to more easily accommodate large trucks.

Construction for Section A is currently scheduled to begin in 2027. Right of way acquisition for Section B is scheduled for 2018, and construction is currently scheduled for 2020.

Proposed Designs

Maps showing the conceptual designs for both U.S. 15-501 and the U.S. 1 corridor are linked above. The project team is early in the design process and will continue to refine the designs to address citizen concerns and minimize impacts where feasible.

NCDOT has proposed the four-lane Synchronized Street design as the best alternative that would have the least impact on property and existing businesses.

What is a Synchronized Street?

A Synchronized Street is a type of intersection that directs left turns and through-movements from side streets to their desired destination by way of a right turn, followed by a U-turn (usually 600 to 1,000 feet from the intersection).

Synchronized Streets improve travel time, mobility and safety on a road. These benefits are achieved through changes to the road that limit left-turn movements and reduce the potential for crashes.

Project History

The congestion and safety needs on U.S. 15-501 and U.S. 1 were first identified in 2011 as part of the Moore County Comprehensive Transportation Plan process, which involved nearly 500 members of the public who provided detailed input about five focus areas in Moore County, including the U.S. 1 corridor through Southern Pines and Aberdeen.

Based on local input from the 2011 meetings, as well as safety and congestion concerns, North Carolina and local agencies in 2015 prioritized the U.S. 15-501 and U.S. 1 corridors for state funding.

Following coordination with the town of Aberdeen, NCDOT has segmented the U.S. 1 corridor into two phases. Construction of the section south of Knight Street will be delayed until 2027. The section north of Knight Street will move forward on the current schedule, with construction to begin in 2020.

Traffic Analysis

Traffic studies examined several potential solutions for the U.S. 1 and US 15-501 corridors. Based on traffic projections, a four-lane Synchronized Street is anticipated to operate at acceptable levels of service until approximately 2035 on U.S. 1, and until approximately 2040 on US 15-501.

The studies found that after 2035 on U.S. 1, and after 2040 on U.S. 15-501, the levels of service would degrade due to increased congestion. At that point, a six-lane Synchronized Street would be needed to handle traffic volumes, unless another alternative is identified

Crash Rates

In an analysis of data from October 2009 to December 2016, the crash rate on U.S. 1 in the study area was 463.8, and the crash rate for U.S. 15-501 in the same vicinity was 643.4.

The statewide average critical crash rate is 307.2 per 100 million miles traveled.

Public Involvement

Public Comment

NCDOT Wants to Hear From You

What are your top concerns for the U.S. 15-501 and U.S. 1 corridors?


Documents and Maps for Public Review

The N.C Department of Transportation is asking the public for its participation in an online questionnaire to help the NCDOT project team understand the top concerns for the U.S. 15-501 and U.S. 1 corridors.

In addition, the public can also submit comments via email or by mail to:

Jeffrey L. Teague, P.E.
NCDOT Division 8
902 N. Sandhills Blvd.
Aberdeen, NC 28315

Comments received by Oct. 20, 2017, will be reviewed and incorporated, where feasible, into the next phase of design.

Public Meetings

NCOT is also holding the following open house to provide an overview of the proposal, including an explanation of how Synchronized Streets work.

Monday, Sept. 18, 2017
4-7 p.m.
Aberdeen Recreation Center

NCDOT will provide auxiliary aids and services under the Americans with Disabilities Act for disabled individuals who want to participate in these meetings. Anyone requiring such services should contact Diane Wilson, NCDOT Senior Public Involvement Officer, at (919) 707-6073, as early as possible so that arrangements can be made.

For individuals who speak only Spanish or have a limited ability to read, speak or understand English, interpretive services will be available at the meeting upon request. For more information, call 1-877-370-6737 prior to the meeting.

Public Outreach

In addition to a public meeting, the NCDOT project team will also meet again with staff from the towns of Aberdeen and Southern Pines, including emergency responders and representatives from Moore County Schools.

Business-Focused Small-Group Meetings

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.
