TRAVEL ALERT: Downtown St. Louis Highway & Street Closures
Travel Alert: MO Department of Transportation is monitoring a sinkhole under I-44, that has caused some highway and street closures in downtown St. Louis. While our attractions remain fully accessible, traffic patterns nearby may be a little different than usual. If you are visiting the Gateway Arch or the Gateway Arch Riverboats, we recommend planning for extra travel time and potential delays.
