Traffic is nowhere near as bad as other major metropolitan areas, but is common during rush hours in the morning, noon and afternoon. Further south, and also from the east, is highway I-255. It is the major road link for Clayton and the Airport. Parking is plentiful and varied, but in congested areas can be hard to find during business hours or popular events. Watch out for posted signs that tell you when to park or expect to be ticketed or towed.
Parking meters are prevalent.
Commercial lots and garages are available in the downtown area and Clayton. There are many options when it comes to travel to and from St. Louis.
