Tools and bike pump at the trailhead. Do your research on this area before you go, as it's both interesting and a little scary. Don't drink the water, and keep moving.

The connector to Research Park is closed due to bridge issues. Signs at the bridge indicate the problem is more serious than originally thought and the connector is likely to be closed until spring of 2017.

Yep, looks pretty bad, here's a photo:

Wow...It sure appears that this bridge was designed with pedestrian and bike traffic in mind, not 2 ton commercial vehicles.

KBLS on 03/14/2017 07:26 AM:
I have been told that the bridge is now repaired within the past week. Can anyone confirm this?

Rich from Saint charles on 03/14/2017 08:16 AM:
Yes everyone the Duckett Creek Bridge on the Busch Greenway is open nowk6FW2R

Maryjo from St Charles on 03/14/2017 08:38 AM:
Thanks Rich looking forward to hitting the trail.

Has anyone ever parked their car here overnight? Is it even possible to leave a car there overnight?

I am planning on riding for 2 nights and need to leave my car around Weldon Spring and I hear the Weldon Spring trailhead is not that safe.

I left mine here for 1 night in Sept., 2012. Had no problem.

dave from high ridge on 03/16/2016 03:54 PM:
Any updates on this? I want to leave a car overnight this spring

There's a park and ride commuter lot near 94&40 intersection at Research Park up the hill from the Research Connector Trail Head. I don't know the rules, but it seems like there would be at least some cars parked there at any time of day.

If the weather is pretty good the Weldon Springs trailhead is pretty busy. Only problem the late hours. I would leave the vehicle and place a sign inside that says,"Vehicle equipped with remote surveillance with direct contact to local law enforcement authorities". It could work.

We have left cars at the Ducket Creek/Bush Greenway trailhead several times for a weekend and have not had any issues. Maybe we have been lucky, we usually leave Saturday morning and return Sunday evening.

The Weldon Spring Trailhead has a self serve bike maintenance station/air pump at the trailhead. I thought I was seeing things this morning, but I am sure it was real.

Jim W from St Louis on 06/28/2015 06:16 PM:
Noticed the bicycle tools (cable attached) and tire pump--nice additions. Hopefully this is a test to see if they will be treated respectfully and will be incorporate into other trailheads.

Jim from St Thomas on 06/28/2015 07:54 PM:
They have had the same setup at the JC trailhead for a while now and I think at least one other trailhead on the western end. It would be nice to have these at a minimum of every other trailhead.

Cathy from Jefferson City on 06/28/2015 08:37 PM:
I think I saw one at Hartsburg today. They may have installed them at several, most trailheads. Does anyone know who paid for them? I am guessing it was DNR. Whoever it was, god Bless them.

Oh, and the trail between Jefferson City and Hartsburg was great today. The condition was fine. There was a lot of water along the trail, but none on the trail.

Cathy from Jefferson City on 06/28/2015 10:14 PM:
Sorry, I should have capitalized God in the previous post. God bless whoever put those bike maintenance stations/air pumps at the trailheads.

Does anyone know if there is a place to camp, or at least pitch a small tent near Weldon Spring? Planning a trip through there in Sept.

Anonoh on 05/27/2015 07:08 AM:
You may need dosimetry if you camp overnight around there. Defiance, Augusta west or St. Charles east would be less toxic.

Sharonbikes from Kansas City on 05/27/2015 07:46 AM:
Weldon Springs Conservation area may allow camping, I'm not sure. Plants in Weldon Springs processed uranium ore during WWII and there is large uranium containment site not far from the Trail. Klondike Park just east of Augusta is a great place to camp. Nice shower house and a camp kitchen with a two burner stove, sinks and electric outlets.

During my last leg of the Katy Trail into St. Charles, I did a bad job of watching the level of my water bottle. With neither Defiance nor Weldon Spring offering water and the sun beating down on me, I was looking for relief. Across the street from the Greens Bottom trailhead (about 5 miles outside of St. Charles) there is Thies Farm (http://www.thiesfarm.com), which had fresh produce, pies, and water/drinks. They even offered to let me fill my water bottle.

Went through this detour area this weekend. The detour is not marked well (esp when the sun is shading the signs). Ended up accidentally riding up the Hamburg trail for a bit before a nice cyclist told me to turn around and pointed out the detour. Several others were making the same mistake as I passed by.

merkin4 from St. Peters MO on 10/03/2011 02:39 PM:
I'd have to agree with this. Keep in mind that you'll want to make the sharpest turn you possibly can of the routes offered, both when going west and east. The trail just about doubles back upon itself - remember that and you should be fine.

merkin4 from St. Peters MO on 05/17/2011 01:13 PM:
Highway 94 is undergoing construction between 64/40 and Defiance MO. For the next two weeks (mid and late May 2011) the road is closed, cutting off all drive-in access to the Weldon Spring trailhead.

Alternatives in the area include access from the Business Park trail to the northeast, or Defiance to the southwest. The Business Park trailhead starts near a sewage treatment plant, and the mosquitos seem to be fierce and impervious to any repellant short of a flamethrower.

merkin4 from St. Peters MO on 05/31/2011 02:53 PM:
Highway 94 is again open, and auto access to the Weldon Spring trailhead parking lot has been restored.
