I have not yet found a 32” tall bridge railing that is installed on an 8” tall sidewalk. I have found a couple that utilized a 42” height.

 

TL-2 BR27C Bridge Railing w/ sidewalk – 42” above sidewalk

TL-2 BR27D Bridge Railing w/ sidewalk – 42” above sidewalk

Any luck in finding a 32” tall vertical face parapet mounted on an 8” sidewalk that meets TL-2?  We’ve verified that our parapet meets the structural requirements to resist TL-2 loads, but still need confirmation that the geometry meets crash test requirements (32” vertical face parapet mounted on an 8” sidewalk).  We’ve been using this standard for a number years and need to decide if we should discontinue its use, and if retrofitting of past installations is necessary.

I had only found the 42” tall railing systems with advance sidewalk. I have emailed Dean Alberson at TTI to inquire whether they have tested shorter variations at 32” with sidewalk.
