Bypass 4 Widening Project Overview

Illustration of Changes MadeThrough cooperative planning by the City of Fairfield and Butler County Transportation Improvement District (TID), the SR 4 Bypass is being widened to four lanes from SR 4 to SR 129. A 6 lane section will run from Symmes Road to Tylersville Road. A Superstreet Intersection design will be utilized for the intersections of the Bypass with Hamilton-Mason, Tylersville and Symmes Roads. (local news clip and ODOT information/contacts)

Within the City of Fairfield, the intersection of the Bypass and Port Union Road will be widened; an additional bridge over the CSX railroad will be constructed; and the intersection of the Bypass with State Route 4/Ross Road will be modified to utilize a new Quadrant Roadway Intersection (PDF) design that will split the traffic between multiple intersections, improving the flow of traffic. See the remaining links for more information on this design. FHWA’s full Alternative Intersection and Interchanges Report can be viewed in its entirety at FHWA’s website.

In addition to the widening between SR 4 and SR 129, the TID is working on a potential plan for lanes north of Route 129. The initial widening, however, will only involve the Bypass to the south of SR 129.

Left Turn Traffic Pattern Changes at Route 4 - Starting January 2012
