The Historic Route 66 Flea Market in Granite City is a year-round market that features individual Vendor Units with lighting, electric, and secure roll-down fronts. The Flea Market itself is open Saturday and Sunday, but vendors are free to open any days or hours they wish, provided they vend on weekends with everyone else. We also offer Day Spaces for 10x10 booths on Saturday and Sunday at $30/day or $50/weekend.
