First "Super Street" Intersection Designed in Ohio (October 2008)
M.E has designed the first "Super Street" intersection in Ohio in association with the S.R. 4 Bypass widening for the Butler County Transportation Improvement District (BCTID). The use of traditional widening techniques (short of a full interchange) would result in an unacceptable level of service (LOS) in the 2030 design year on S.R. 4B from the interchange with S.R. 129 to the intersection with Dixie Highway. Therefore, alternative design methods were considered to reach and maintain an acceptable LOS for projected traffic volumes.

What Exactly is a "Super Street"? The "Super Street" intersection design improves operation on the main road by reducing stops for through traffic on the major road and delay for left turns onto the minor road. The "Super Street" design eliminates movements or signal phases from the minor road. This allows the intersections to operate more efficiently by overlapping turning movements. Traffic on the minor road cannot proceed straight through the intersection and is instead redirected to 1) take a right onto the major road, 2) make a U-turn through a median crossover, and 3) turn right to proceed on the minor road (see graphic). Because this type of intersection design decreases delay time at the signals on the major road and only slightly increases the signal delay for the minor road traffic, this design is most appropriate for intersections where the major road experiences high through volumes and the minor road lower through volumes. States using some form of "Super Street" design include Michigan, North Carolina, and Maryland.

S.R. 4 Bypass Widening Project - The project involves converting this two-lane state route into a four-lane facility. The "Super Street" design is being considered for three locations along the corridor, including the S.R. 4B/Symmes Road intersection. The BCTID and ODOT will study "Super Street" installations at other locations out of state before work begins on S.R. 4B to assess and minimize potential problems. In addition, the BCTID, ODOT, and the Greater Hamilton Chamber of Commerce will cooperate in educating the public on the new traffic pattern and issuing frequent communications regarding project progress.
