Vehicular rail height is 3 feet – 0 inches above the bridge deck or Finish Grade. Bicycle railing height is 3 feet – 6 inches above the bridge deck or Finish Grade. For accesscontrolled freeways and expressways where bicycle traffic is prohibited by signage on the on-ramps, the bicycle railing (includes Bar 3 x 3/8 x 8" and above) may be omitted. In some instances, the District or stakeholders may have other reasons to include the bicycle railing at locations where bicycle traffic is prohibited. Width is 2 feet – 0 inches.
Post spacing is 10 feet – 0 inches maximum. Post spacing between BB and EB should be equal spacing. Post spacing on wing walls may be different than on bridge deck. Aesthetic see-through railing.
