Katy Trail Rock Island Spur Comments
370 Bridge

Does anyone know if it is illegal to ride across the 370 Bridge since it isn't marked with bike lanes anymore? My second question is when are they going to re-stripe the bridge to put the bike lanes back.

Here is the statement MoDOT has on their site.

Route 370 Temporary Bike Lane Closure.

MoDOT closed the bike lane on the Route 370 Missouri River bridge in November 2011. The Route 370 bridge is restriped to add a fourth lane on 370 between Earth City Expressway and Route 94. The extra lane will help traffic during the closure of the westbound I-70 bridge. The fourth lane on Route 370 will be removed in 2014 and the bike lane will be restriped by mid summer 2014. During the closure, cyclists should use Route 364 Page Avenue to cross the Missouri River.

Here's the link with the detour map.

I read that but what I want to know is if it is illegal to cross the bridge. I am planning on doing an end to end ride in late June ending in Machens and I live in North County so it will add about 15-20 miles to go all the way down to the page avenue bridge. It would be much easier if I could just cross the 370 bridge. There is still a shoulder on the bridge so it shouldn't be to dangerous to cross there if traffic isn't to bad. Thanks for the input.

370 is listed on the 2013-2014 Bike Path Map on MODOT's website. Probably not illegal. If you are really concerned, contact MODOT or the Highway Patrol. Not sure but, I always thought that bikes could travel on all MO highways unless they were specifically marked as forbidden.

Here's a relevant statute:
307.191. Shoulder Riding, Allowed But Not Required For Bicyclist Operators (1) A person operating a bicycle at less than the posted speed or slower than the flow of traffic upon a street or highway may operate as described in section 307.190, or may operate on the shoulder adjacent to the roadway. (2) A bicycle operated on a roadway, or the shoulder adjacent to a roadway, shall be operated in the same direction as vehicles are required to be driven upon the roadway. (3) For purposes of this section and section 307.190, “roadway,” means that portion of a street or highway ordinarily used for vehicular travel, exclusive of the berm or shoulder.

My understanding is the only time you can't ride in a traffic lane is when you couldn't ride at the minimum speed posted such as an interstate highway. Even then its legal to ride on the shoulder.

Possibly not illegal, but definitely suicidal. 65mph traffic with no shoulder? don't do that.

One Missouri interstate highway has designated bike lanes on the shoulder. It is the only Interstate highway anywhere that I am aware of that has this. The Hannibal, MO to E. Hannibal, IL bridge of I-72 across the Mississippi River:

Where do I start? Why do I bother?

MO-370 is not an interstate.

Several Western states, including CA, NV, UT, AZ, and CO, allow riding on the shoulders of rural interstate highways.

Don't see anywhere in the thread that anyone referred the 370 bridge to an interstate other than you?
