Here is my preferred route from the Katy Trail to the Kirkwood Amtrak station by riding through Chesterfield, Clayton, and Kirkwood:

Here are some of the highlights: the river crossing and levee trail are nice and paved, crossing the interstate and cutting through the shopping mall parking lot is not difficult, the zig zag route through the Chesterfield Valley is not bad and often there is a nice sidewalk available if you want to take a break and get out of traffic, especially going uphill, the one way 40 Hwy outer road has a nice wide shoulder, it is fun crossing Hwy. 141 and taking the "secret" Salt Mill Road connection to Old Woods Mill and connecting to Clayton Road, take the sidewalk on the north side of Clayton Road east for just over 1 mile and then that sidewalk turns into a nice paved trail for the next 3 miles, Ballas Road south of Clayton Road has a nice bike lane all the way south down to Manchester Road (Route 100), and finally you just cross Manchester Road at a signal and zig zag through the nice residential streets of Kirkwood to the train station.
