This road cycling route goes from the Machens trailhead of the Katy Trail
to the Amtrak station in Alton, Illinois. If you are looking for the
reverse route, it is here: Alton Amtrak
to Machens.
There are other Katy-Amtrak options in
the St. Louis area, most of which are longer.
From the Machens trailhead, follow the trail northeast to the
very end, where a gravel road crosses. Turn left, which
follows the railroad tracks for about 200 feet, then turn
right to cross the tracks. Take Machens Road north, about 2100
feet, until you reach the highway (MO-94).
Turn right (east) onto Hwy 94. Follow the highway until it
reaches US-67, about 8.4 miles. Ride across to the
north-bound lanes. (There are a couple of gas stations here,
where you can buy water or snacks.)
Turn left (north) on US-67. You'll be on this highway for
about 3.4 miles, which includes the ride across the Clark
Bridge and the Mississippi River.
Turn right (east) on to Landmarks Blvd. (IL-143). This route loops
around to the right, which adds about a mile to the total route, but
in my estimation, making a left turn at this intersection is too
daunting for most casual riders.
In 2300 feet, turn right onto Discovery Parkway.
Discovery Parkway becomes Ridge Street as it loops around to the north.
Ride straight across US-67 at the traffic light, and the 3% climb
starts soon after.
Turn left (west) at 6th Street.
Turn right (north) at Liberty Street. Keep climbing Liberty Street for
0.7 miles.
Right right (east) at Grove Street.
In two blocks, turn left (north) at Central Avenue. Ride around to the
far side of the traffic circle. The road will eventually become
Tonsor Road and make a couple of turns toward the right.
Turn left (north) on Toledo Avenue.
Turn right (east) on Oakwood Avenue.
Turn left (north) on Buckmaster Lane. Ride straight across IL-3 at the
traffic light.
Just after the traffic light, turn right (east) onto Baron Commerce
Parkway.
Turn left (north) on Golf Road.
Turn right (east) to continue on Golf Road. Follow all the way to the
end, and then turn left into the station.
