The objective of this synthesis is to document practices used by state departments of transportation (DOTs) for designing and maintaining roadsides adjacent to urban freeways. The synthesis focuses on high visibility freeway roadsides with limited pedestrian access. These areas often have wide medians, interchanges, and overpasses. Information used in this study was gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected agencies. Three case examples illustrate agency practice on this topic. The full report is available at http://www.trb.org/Publications/Blurbs/179339.aspx
