 Most days, the corner of South Columbus and East Balbo Drive, four lanes in every direction, average speed is about six miles an hour. Well, they've divided it in half diagonally now. They'll come down the front straightaway, otherwise known as South Columbus, and hit a hard 90-degree left-hand turn number one. They'll then spill out onto East Balbo Drive for a short sprint, a short straightaway, then a right-hand turn number two.
