Centennial Way Federal Aid Transportation Enhancement

Project Owner: City of Phoenix
Project Type: Design-Build
Construction Dates: 05/11 to 02/12

The Centennial Way project transformed Washington Street and the Arizona Capitol Mall entrance into a beautiful streetscape for residents and visitors to celebrate Arizona's 100th birthday (February 14, 2012) as well as the State's history and culture. The project consisted of roadway improvements (Washington and Adams Streets from 7th Avenue to 19th Avenue) including curb & gutter, sidewalk and pedestrian ramps, a consistent 6” vertical curb reveal along the corridor, and a rubberized asphalt overlay. Major project features included eight thematic major shade structures providing historic and current information relative to the theme, a “Tribal Walk” showcasing Arizona’s 22 Native American tribes, 15 county displays, seven wayfinding signs, seating nodes, solar power elements, additional palm trees, pistache and elm trees for added shade along the corridor, planting nodes, landscape irrigation systems, new energy efficient LED street and pedestrian lights, and the undergrounding of existing overhead street light power.
