Osborn Road Improvements

The project begins just east of Scottsdale Road and ends just east of 81st Street, west of Hayden Road. This project also includes portions of the north and south legs of the Osborn Road and Miller Road intersection.

A “complete streets project” means that the corridor will be designed and constructed to allow safe access for all modes of transportation, including pedestrians, bicyclists and vehicles of all sizes.

Major issues driving the need for this project include improving safety and corridor connectivity for all modes of transportation. This project was identified as part of City of Scottsdale’s 2016 Transportation Master Plan as a roadway segment in need of safety and connectivity improvements to increase the quality of life for residents, businesses and the traveling public.

No, Osborn Road will remain two lanes of vehicular travel in each direction.

Changes are being made to the intersection of Osborn Road and Miller Road to improve the safety of the intersection primarily based on accident history. The changes will increase intersection safety, establish multi-modal traffic accommodations, and corridor connectivity.

During the pre-design phase, multiple intersection configurations were studied & analyzed. Ultimately, it was determined that a roundabout will reduce the number and severity of vehicle crashes, make the intersection more efficient by increasing both the AM and PM levels of travel satisfaction, reduce vehicle speeds that will improve safety of the corridor and the interactions between bicycles, pedestrians and vehicles.

The project will install new pedestrian ramps, sidewalks, driveway connections, new signage and new striping to accommodate bike lanes and cross walks. Highly visible Rectangular Rapid Flashing Beacons (RRFB) signals will be installed at each crossing and on all corners of the roundabout. These RRFB’s are activated by pedestrians when crossing Osborn or Miller Road and will alert the approaching traffic accordingly with high-intensity patterned strobe lighting. Street and pedestrian lighting will be installed at the roundabout to make sure pedestrians can be seen by traffic any time day or night.

Proposed median and parkway areas will receive new landscaping, irrigation, hardscape and potential art components. The planting pallet includes a variety of natural southwest desert oasis vegetation including Pine and Oak trees as well as natural ground cover including Hesperaloe, Daisies and Bougainvillea. These new areas will enhance the adjacent existing landscaping to blend in with the surrounding area. The remainder of the landscaping effort will restore existing landscaped areas disturbed as a result of construction. Existing plant material, hardscape and irrigation will be restored to match, or make better.

Street and pedestrian lighting will be installed at the Osborn and Miller roundabout to make sure pedestrians can be seen by traffic any time day or night. The project will not light the entire roadway, but will install lighting to enhance the safety at mid-block crossings at the hospital, west of Drinkwater Boulevard. Lighting will also be installed or enhanced at the new retaining wall connecting Osborn Park to Osborn Road to make sure pedestrians and bicyclists can see where they are going at night.

The project is scheduled to be complete at the end of April 2023.
