A major use of Mechanically Stabilized Earth (MSE) walls is as bridge approach embankments, where they are typically constructed with a roadside barrier system supported on the edge of the walls.

The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 326: Design Guidelines for Test Level 3 through Test Level 5 Roadside Barrier Systems Placed on Mechanically Stabilized Earth Retaining Walls is dedicated to developing guidelines for barrier-moment slab systems placed over MSE walls to resist vehicular impact loads resulting from three test levels.

Supplementary to the document is a Presentation.
