Highway Planting and Irrigation

As the Departmental lead responsible for the design of the highway roadside, the Landscape Architecture Program provides expertise in the planning, design, construction, maintenance and operation of transportation system improvements that:

• Balance mobility, safety, maintainability and economic needs with adjacent land use and aesthetic, environmental, scenic and community values;
• Improve traveler safety through the design of context sensitive roadways for motorists, transit, bicycle, and pedestrian users;
• Improve traveler and worker safety by providing solutions that reduce the frequency and duration of maintenance worker exposure to traffic;
• Improve traveler safety through the design of safety roadside rest areas and management of rest area system needs.
