Within the project area, I-40 currently consists of a rural four-lane, controlled access facility with a grass median and approximately 300 feet of right-of-way (ROW). SR-196 is currently a rural two-lane, non-access controlled road with a pavement width of 22 feet and approximately 60 feet of ROW.
The proposed project would include construction of a standard diamond interchange that permits future construction of loop ramps within all four quadrants. Orr Road, which currently intersects SR-196 immediately south of the interstate, would need to be relocated south of its present location to allow for the construction of the ramp in the southwest quadrant of the proposed interchange. The cross section on SR-196 will be three 12 foot lanes within the interchange: two 12-foot traveling lanes, a 12-foot continuous left-turn lane, and 10-foot shoulders. All interchange ramps would have 16 foot lanes and 6-foot shoulders. The realignment of Orr Road will be designed to meet minimum standards.
