Shared-use ramp handrail

[ACtrafficengr]

On a ramp connecting to a shared-use path, a handrail at 34-38" is needed, as is a top rail at 54" for bicyclists. A bicyclist is likely to go over a 34" handrail.

I'm looking for details on how to incorporate these requirements, along with the handrail returns at the ends of the railings. If the handrail isn't the top rail, does it need to be mounted on the inside of the posts? I take it the handrail would get a return, but not the top rail.

Thanks for any advice. I'd especially appreciate photos, details, specifications, etc.

AC...I would err on the side of the ADA....Put the 34" rail inside. The bikers don't really need a rail, but if your code requires,....provide.

Thinking about it some more, I may have asked the second question first. The situation is a business owner is asking for a safe, ADA compliant access ramp up the embankment to our rail trail. The ramp grade will be 8%, so a handrail is needed.

I think my question should have been: If the railing is just a handrail because of the ramp's grade, and isn't a protective rail, is the higher bike rail needed?

If a railing will also serve as protective rail because of a drop-off behind the rail, then IMHO, the bike rail is needed. The design guidance docs I have say "should," not "shall," but I can't think of a good reason not to. As they say, Murphy was an engineer.

Agree on the ADA determination, but not clear on how the bicycle railing is being triggered? My experience has been a drop off condition warrants the bicycle railing whereas the ADA railing can be viewed as an assistance device to supplement using the ramp itself. I don't believe that an ADA railing in and of itself would trigger a bicycle protection railing to supplement it. Since you mention a drop off along the ramp, maybe my question is moot.
