The project logo U-5891: NC 50 (Creedmoor Road)

 

The N.C. Department of Transportation is proposing to widen N.C. 50 from I-540 to north of N.C. 98. 

N.C. 50 is a two-lane highway that is operating over capacity.   Existing traffic volumes (2018 Average Annual Daily Traffic - AADT) are as high as 25,900 vehicles per day and in the future (2045) are expected to be as high as 30,000 vehicles per day in the corridor between I-540 and N.C. 98. 

In addition to decreasing congestion, enhancing mobility, and providing an improved north-south arterial connection in the region, the widening of N.C. 50 would enhance economic development, better connect rural areas with jobs, and provide a safer roadway.

Project Highlights

This project would widen N.C. 50 (Creedmoor Road) between I-540 and just north of N.C. 98 from a two-lane roadway to a four-lane divided roadway with a 23-foot raised median. 

Two concepts are being considered:

  • a traditional roadway and intersections

  • a reduced conflict intersection (RCI) corridor

Both alternatives would have curb and gutter from I-540 to Norwood Road and a shoulder section from Norwood Road to north of N.C. 98.  The recommended alternative may include elements of both the traditional and RCI designs. 

In addition, two options are being considered for the interchange of N.C. 50 with I-540:

  • improving the current diamond interchange

  • reconfiguring to a Diverging Diamond Interchange (DDI). 

The bridges on I-540 and N.C. 98 over N.C. 50 would not be affected with this project.


What is a Reduced Conflict Intersection?

While main street travelers may turn left, right, or travel straight through  - just like at a conventional intersection - side street travelers who wish to cross or turn left at a reduced conflict intersection must first turn right and then make a U-turn to continue on their desired route.

The purpose of a Reduced Conflict Intersection is to improve vehicular mobility and safety by limiting the number of conflict points between vehicles during traffic maneuvers. A Reduced Conflict Intersection design reduces the potential for collisions by limiting the number of left-turns and moves traffic through an intersection more efficiently, ultimately translating into shorter travel times.

Reduced Conflict Intersections can help alleviate congestion while increasing travel capacity. Improved traffic flow is possible by simplifying traffic signal phasing (e.g., eliminating the need for left-turn signals or cutting down on the time spent at a traffic light) and allowing both directions of traffic to move simultaneously.

What is a Diverging Diamond Interchange (DDI)?

A diverging diamond interchange allows two directions of traffic to temporarily cross to the left side of the road. This movement provides easier access to an interstate.   A DDI moves high volumes of traffic through an intersection wtihout increasing the number of lanes and traffic signals.

Benefits

A Diverging Diamond interchange allows free-flowing turns when entering and exiting an interstate, eliminating the left turn against oncoming traffic and limiting the number of traffic signal phases. It is also easy to navigate, eliminates last-minute lane changes and provides better sight distance at turns, which results in fewer crashes.

The interchange also reduces congestion by allowing traffic to keep moving through an intersection. 

Cost-Effectiveness

For improvement projects, a Diverging Diamond interchange often uses the existing bridge structure and the existing right of way, which eliminates the cost of building new structures and purchasing additional right of way.
 
Because many of the existing interchange features remain intact, the Diverging Diamond interchange is often built in less time than it would take to build a new interchange and with significantly less impact to motorists.
 
A Diverging Diamond interchange usually requires the purchase of less right of way and the construction of fewer lanes and bridge structures than traditional interchange types.

Project History

In January 2011 the Capital Area Metropolitan Planning Organization (CAMPO) completed the N.C. 50 Corridor Study. 

The  Study recommended:

  • widening N.C. 50 to a four-lane median divided roadway from I-540 to Norwood Road

  • realigning Nipper Road and Shooting Club Road

  • reducing the speed limit to a consistent 45-50 mph

  • providing wide outside lanes for bicycles and a multiuse path between NC 98 and Old Weaver Trail. 

On February 19, 2018 a Feasibility Study was completed by NCDOT for the project.  The Feasibility Study recommended:

  • widening to a four-lane divided curb and gutter section

  • upgrading the I-540/N.C. 50 interchange to a Diverging Diamond Interchange (DDI) 

  • realigning Shooting Club Road to intersect Nipper Road 

  • signalizing the intersection of Club Road and Nipper Road 

  • upgrading the interchange of N.C. 98 and N.C. 50 with two one-way bridges on NC 98

Preliminary designs for the project are being developed.  The impacts of those preliminary designs will be analyzed and documented in the project's Environmental Document, a Categorical Exclusion (CE).  The CE is scheduled for completion in August 2019.

During this project development phase, an alternative will be recommended.  Once this phase is completed, the project will move into final design and is scheduled to begin construction in  October 2024.

RESOURCES FOR 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.
