Officials at Iowa Speedway encourage race fans to arrive early and be patient when driving to this Sunday’s Iowa Corn Indy 250. They are hoping to limit congestion in and around the speedway.

General Manager Craig Armstrong says it’s just like an Iowa-Iowa State football game, come early tailgate and enjoy. The parking lots open at 5 a.m.

Armstrong says several law enforcement agencies are working with a private traffic control company to make sure things run smoothly. He says it’s important for people to be patient, as their goal is to keep traffic flowing.
