Abstract:

Currently, the Louisiana Department of Transportation and Development (DOTD)

maintains approximately 200 miles of concrete safety walk barrier railing systems on

its bridges. Some of these vintage systems do not meet the current crash performance

requirements of the American Association of State Highway and Transportation Officials’

Manual for Assessing Safety Hardware (AASHTO MASH) specifications.

Most existing safety walk bridge barrier railing systems consist of a concrete curb, a

concrete safety walk, and a concrete parapet or post and rail system. The safety walk

on these bridges is desirable for bridge inspection/maintenance activities, and for

general safety of stranded drivers or pedestrians. Retrofits that meet the current MASH

requirements for Test Level 4 (TL-4) and maintain the concrete safety walk are needed.
