Soon, we find ourselves passing Lewisburg at an interchange at Ohio State Route 503 as we push into the western edges of the Dayton metro area. Entering the metro in Brookville, we cross the interchange with Ohio State Route 49 north (Greenville) and shortly after, the interchange with OH-49 south (Trotwood).
Interstate 70 never officially travels through the City of Dayton, but rather the northern suburbs. The closest I-70 gets to being in Dayton is at the Airport interchange (exit 32), and that is a mile north or so at the closest. Passing the Airport interchange, we exit I-70 and end the video at the interchange with Interstate 75 south (Dayton).
