Two ways to ride: Get off the trail at HWY 394 for Creve Couer. There is a seperate bike trail on the bridge. From there it is easy to find a route to the STL airport. Then take the tram into the station, or all the way to the arch and ride the short distance back to the station. Option two is to continue on the trail to Machens (end of trail) then a short highway ride to the Mississippi, ferry across, then down the trail on the Illinois side. This crosses back over to the Missouri side and a trail into the arch area of STL.
