Discussion
The barrier run may be flared to the limits of the clear zone. The existing shoulder slope or median slope may be too steep for this type of installation. If this is the case, temporary grading should be provided or a different end treatment should be used. The Roadside Design Guide contains recommended barrier placement in non-level medians. These guidelines also apply to outside shoulders.
