Boosting safety and mobility in North Carolina

A new half-clover interchange at Kerr Avenue in Wilmington will increase capacity and improve traffic flow.

Like many US states, North Carolina faces the challenge of deteriorating transportation infrastructure and increased congestion. The North Carolina Department of Transportation (NCDOT) has established a Strategic Transportation Improvement Program to meet the needs of the state’s taxpayers.


Mott MacDonald’s local offices are providing planning and design services for hundreds of projects on behalf of the NCDOT. These include planning and design projects for highways and bridges, including rural and urban widening projects, bridge replacements, intersection and signal designs, and the design of interchanges.

One example is the at-grade intersection of Kerr Avenue and Martin Luther King, Jr. Parkway in Wilmington. The intersection is highly congested, causing delays and safety issues for local residents. Mott MacDonald designed a new half-clover interchange to replace the existing at-grade intersection.


Although much of our work in North Carolina consists of small “bread and butter” projects, NCDOT recognizes that these projects are increasing mobility, improving safety, and providing a higher level of service to its citizens.

The half-clover Kerr Avenue interchange, for example, will help increase capacity and improve traffic flow, improving the quality of transportation in the Wilmington area.
