The metrolink runs East-west St. Louis. It takes u east to St. Louis downtown area (ball games, bar/clubs, restaurants, Laclede’s landing, Arch, etc etc and u name it). But the metro doesn’t end there. It continues to run eastward to IL area. Westward, it takes u to the Lambert airport. It is closely on time. About ten mins in between rides. Less than $2 per ride or u can purchase One day pass, 2 hr pass, monthly pass, student pass… etc. Convenient transportation.
Downside: (or positive side) They rarely check for ur tickets.
