The Project
RK&K served as the Lead Designer for the widening and improvements of I-40 from the I-40 / I-440 / US 64 interchange in Wake County to just north of SR 1525 (Cornwallis Road) in Johnston County. As one of the most heavily traveled and congested transportation facilities in the Raleigh, North Carolina area, this project provided a higher level of service on I-40 and relieved present and future traffic congestion.
The 12.8-mile-long project consisted of ten-lane, eight-lane, and six-lane sections and was designed to meet 70 and 75 mph for freeway interstate standards. In addition to widening, this much-needed project included six interchanges (partial cloverleaf, system to system, diamond, and diverging diamond), 15 bridges, replacement and extensions of numerous box culverts, and sound barrier and retaining walls. The flyover ramp bridge at the I-40 / I-440 interchange was a complex bridge design and included horizontally curved steel girders (radial bents) with span lengths that exceeded 200 feet in length.
RK&K also completed a detailed Interchange Alternatives Assessment for possible modifications at the I-40 / Jones Sausage Road interchange.
