About the research

Provide guidance to county engineers for replacement or upgrading bridge and bridge approach guard railing by:

  • Determining the criteria and guidelines used by other states for bridge and approach guardrail implementation for low and very low-volume roads.
  • Performing benefit/cost analysis for using bridge and approach guardrails based on traffic levels and road classifications.
  • Investigating the use of non-standard and innovative bridge and approach guardrails for low-volume roads.
