Option 'C' proposes a "Superstreet" design that creates an extended intersection that would circulate traffic more efficiently through the US 15-501 and Erwin Road/Europa Drive intersection. The presentation below shows artist depictions of how the intersection would look using the Superstreet Design.

With the proposed “Superstreet” design, access is partially controlled at the intersection of US 15-501 and Erwin Road. With this alternative no left turns will be permitted from the mainline (US 15-501) onto the side streets (Erwin Road and Europa Drive) no through moves will be allowed between the side streets. All turning movements and through movements will be accommodated dual signalized U-turn points approximately 800 feet in either direction from the current intersection along US 15-501. A project that is slated for construction prior to the construction of this project will relocate the Dobbins Drive – Erwin Road intersection further away from the US 15-501 intersection. Widening along southbound US 15-501 will provide for a right turn lane onto Erwin Road. The service road in the northeast quadrant of the intersection will be relocated to accommodate the additional widening due to the U-turn lanes required along US 15-501. The service road connection on US 15-501 northbound just south of the intersection will be closed for safety concerns.
The Superstreet Option would improve vehicular mobility and safety. It would improve pedestrian and bicyclist access with the addition of a multi-use path and fewer total lanes to cross. The "Superstreet" design also improves safety by limiting the number of 'conflict points', or points where vehicles can collide in making traffic maneuvers. By limiting these points, there are fewer opportunities for a crash. Additionally, this option would reduce traffic delay by moving traffic through the intersection more efficiently. This translates into shorter travel times and lower emissions due to traffic congestion.
