Rural Medians and Outer Separations

The entire area of rural medians and outer separations should be 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 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.

Rural Intersections

During spot and strip mowing operations, the area around rural intersections or interchanges will be mowed as necessary to provide adequate sight distances.

Urban Intersections

Urban intersections can sometimes be sparsely landscaped or they can be formally landscaped with turf grass, tree and shrub beds, which can be irrigated or non-irrigated. Often, as in Figure 2-11, the interior areas of these intersections include natural, brush or wooded areas. Because Texas is a diverse state with 11 vegetative regions (see Figure 2-12, below) intersections are landscaped differently within the districts and maintained with various maintenance levels.

Cut and Fill Sections

Normally, on fill sections, only strip mowing will be necessary. Strip mowing will also be adequate in cut sections; however, at deep cuts, mowing must extend across the ditch line to the beginning or base of the backslope.

Rest Areas and Picnic Areas

Rest areas and picnic areas should be maintained in a lawn-type condition with frequent mowing.
