US 68 interchange and altering nearby traffic patterns. The Ohio Department of Transportation (ODOT) the same year approved $5 million to fund the project. However, the TCC soon rejected ODOT's money, concluding that even its recommended fix would not be enough to solve the area road network's underlying problems. Instead, the TCC is making small changes, such as improving traffic signal timing and adding signs. ODOT, for its part, is working on reducing the number of driveways near the US 40/SR 4/Upper Valley Pike intersection and on upgrading traffic signals. In Xenia Township, Greene County, Ohio, north of Xenia, ODOT plans to convert the intersection with SR 235, the state route's southern terminus, to a roundabout. As of summer 2020, construction is expected to begin in spring 2023 and to be completed that fall, with an estimated cost of $2 million.
