Wayne State University 's parking areas near the Lodge Freeway and I-94 in Detroit will serve as one of six locations set up so riders can park their cars and catch a downtown bus during the period leading up to the Super Bowl when street parking is banned and streets are closed throughout downtown. Parking is $10 at WSU and the zoo, but free elsewhere. Return shuttles running every 15 to 20 minutes will pick up riders at the same location, with limited runs after 3 a.m. each day.
