This 2.5-hour workshop explores the basics of longitudinal roadside barriers. Together we will discuss why and when barriers are needed on the roadway, review the types and characteristics of barriers, and find out where to locate guidance for placing and installing barriers. Finally, we will review maintenance requirements for roadside barriers and discover the important role maintenance plays in keeping the barriers performing as they should.

You’ll have a chance to use resources, such as the AASHTO Roadside Design Guide as well as Nevada-specific design guides and specifications, to answer questions and make decisions about real-world scenarios you might encounter when placing barriers.
