The spacing of the RCUT crossovers from the intersection is central to the proper functioning of the intersection. The typical location for the median opening at an RCUT intersection with stop sign or signal control is 400-ft to 800-ft. downstream of the minor road.

The median width is a function of the design vehicle (typically a WB-62TX or WB-67) and the preferred alignment of the design vehicle as it turns into the opposing traffic; see for discussion on Median U-Turn Movements. For instances where the U-turn can’t be completed using the existing pavement, a loon type configuration with back-to-back storage bays may be used to provide additional space. See and for spacing considerations for a minor street through or left movement. Designers must also ensure good intersection sight distances at RCUT crossovers by making sure slopes and plantings in the median are cut back beyond the lines of sight.

illustrates an RCUT scheme showing the extension of left-turn lane deceleration for the left-turn lane and for the acceleration lane after a vehicle exits the U-turn loon. These features are preferred for slow moving vehicles such as trucks and farm equipment that cannot accelerate and decelerate in the distance available between the RCUT and the U-turn. This design concept also affords placement of the U-turn closer to the RCUT. Making it possible to compress the overall footprint with potential space and cost savings.
