Durham, N.C.


We served as Prime consultant for a Mini Roundabout for NCDOT through the Statewide On-Call Planning and Design contracts. The goal of this project was to improve the operational safety of the intersection of Carver St. and Broad St./Kenan Road in Durham, NC. Due to several rear-end collisions and numerous near-misses, a mini-roundabout was utilized to calm traffic while continuously processing traffic through the intersection, thus eliminating the need for side street traffic to compete for limited gaps in the predominant Carver Street movement.

The mini-roundabout approach limited the amount of impact to surrounding property owners but accommodates the turning movement of larger vehicles (transit/school buses, fire truck, etc.) through the use of a mountable center island. Our team provided roadway design, hydraulic design, erosion control design, traffic management and pavement marking design, and utility coordination/design services for the project. Summit also participated in NCDOT’s Public Involvement efforts and provided supplemental route location surveys and easement staking as needed to complete the project. Design and coordination has been completed and the project was let for construction in the Spring of 2015.
