- I had not used this garage for about two years but today, Saturday, thinking the $5.00 flat fee I had paid before, was in effect, I parked there. SURPRIZE!! Public parking, allowed on weekends and after some business hours during work days, is now SIXTY PERCENT HIGHER! It is $8.00 flat fee. No wonder there were not that many cars there today. The 3CDC parking garage nearby at Washington Park offers hourly rates, much cheaper and now offers a Parking Rewards Program. Not parking at Gateway anymore.
