Having been bumped off the trail when we hit the river in Boonville in May, we returned the week of August 18 to complete the trek, as you would expect from stubborn Irishpeople.
Posted detour from Boonville to Franklin is easy to navigate. Bike lane over the bridge is on the west side (facing traffic if you're biking the KT downriver), so we chose to bike opposing traffic on US 40 till you hit the county road. Wide turnout lane, so there were no problems.
There is no official detour at Davisdale, but we crossed US40 and rode with traffic for a little over a mile to County Road 440 for the trip into Rocheport. 440 is gravel and the last downhill is extremely steep - if you don't have disc brakes, opt for another mile on US 40 to County Road 240.
GRIPE HERE - I am sure the highway folks have those nifty electronic / solar signs for traffic announcements. Placing them between on 40 between Davisdale and 240 with a message alerting drivers to bicyclists would be a nice touch. Our host in Rocheport says the bridge at Davisdale is just a part of the problem. DNR Engineering has an ongoing argument over the potential of falling rock just upriver from the Rocheport tunnel. This section could be closed for a LONG time. C'mon, man. You are KILLING these river towns depending upon Trail traffic.
From Rocheport we got all the way to Easley / Cooper's Landing, but the trail got quite soft and we retreated up the MKT trail to Columbia for a shuttle to Hartsburg. You can get about 3 miles upriver from Hartsburg before the trail is blocked. Downriver to Jefferson City was fine, and the bridge access ramp was a hoot.
The "no detour" blockage west of Portland at MM 117-118 forces a ride to MO 94 on Schmidt (?) Road, okay gravel. There are two hills into Portland - the second one is a real groaner, even for bikers like us used to the hills of East Tennessee. We walked up the second. The right turn to the Portland TH is clearly marked.
The closure west of Case at MM 96.9-97.1 was clear when we passed, but they were doing work on the trail and I managed to puncture a tube on the big gravel there.
The closure at Treloar on the DNR website is new. Whatever you do, find your way to the Treloar Bar and Grille. Nice folks.
The detour upriver from Augusta is a breeze.
The detour between Augusta and Matson, through Klondike Park, is a bit more challenging. There are some washouts and a steep (85') climb on the upriver / west side of the detour that required walking the bikes. Once we got to the park roads and around what looks like an abandoned quarry, the biking was a bit slow, but quite managable.
From there to St. Charles was generally in good shape, with the exception that we could find no water hydrants from Klondike to St. Charles.
If you were considering a fall trek on the Katy, DO NOT CANCEL YOUR TRIP!! Generally speaking...with those two highway detours...the trail remains quite passable with tires 28MM or wider. Don't attempt road tires like the guy on the official map! The businesses along the route need your business, and they were consistently friendly despite having such a lousy season.
