Rural Medians and Outer Separations
Rural medians and outer separations should be
limited to a maximum of 30 foot widths
mowed during spot and strip mowing operations, unless the grade is too steep or the area is covered with trees, shrubs or other vegetation desirable for wildlife benefit, aesthetic benefit, pollinator benefit
or erosion mitigation. On extremely wide medians and outer separations, normally only transition and shoulder strip mowing should be performed. This applies to all divided highways including state, U.S. and interstate highways.
