Traffic on the Valley’s arterials is as familiar to daily commuters as the landmarks those roads point to, but many of the names drivers pass without thinking carry distinct local histories. Some streets in central Phoenix follow a presidential or numerical pattern, while others commemorate early settlers, irrigation projects, ranching families, church institutions or the natural landscape. Together they form a map of how Maricopa County’s communities developed from the late 19th century through the postwar boom.
Traffic moves along a major Phoenix arterial toward the downtown skyline, with signs pointing to South Mountain — a modern view of the thoroughfares discussed in the story about street-name origins.
Several names harken back to religious and agricultural roots. Alma School Road takes its name from a late‑1800s schoolhouse; the children in that rural neighborhood — largely Mormon settlers — named the school for Alma, a prophet in the Book of Mormon. Nearby Baseline Road carries both agricultural and surveying history: before residential development, farms and Japanese flower gardens stretched between 32nd and 48th streets, but the roadway’s name actually derives from the Gila and Salt River Meridian Survey begun in 1867, which tied Arizona land claims to the national grid and opened the way for homesteading under the Homestead Act. Bell Road honors Harvey Bell, a farmer who helped organize the Paradise Verde Irrigation District in 1916, a group responsible for the Horseshoe Reservoir on the Verde River.

Other streets preserve institution and personal names linked to the city’s early public health and law enforcement history. Bethany Home Road led to the Bethany Home, a tuberculosis sanitarium operated by a church in the early 1900s that served the region when TB epidemics were a public health crisis. Broadway Road memorializes Noah M. Broadway, who served as Maricopa County sheriff in 1885‑86; Broadway owned a farm that stretched between 7th and 23rd avenues on the south side of today’s Broadway corridor. Cactus Road takes a simpler cue from place — named for the little town of Cactus once located just northeast of Sunnyslope — while Camelback Road is a direct geographical reference to Camelback Mountain, whose ridgeline resembles a resting camel.
Central Avenue’s name and location reflect a deliberate planning choice as the city adopted a numerical grid. The thoroughfare was first called Centre, later Center, and then Central; when Phoenix switched to a numbering system it became the dividing line for the grid. Numbered streets begin to the east of Central Avenue and numbered avenues begin to the west, making Central the spine around which much of downtown and the surrounding neighborhoods are organized.
Several road names recall families who shaped agricultural and civic life in Mesa and greater East Valley communities. Cooper Road memorializes James “Jim” Cooper and his wife, Mildred Post Cooper, who built a dairy near Southern Avenue and Stapley Drive after receiving a single cow as a wedding gift and expanding the operation to a 400‑cow farm. Jim Cooper later served in the Arizona House of Representatives, elected in 1968; the family grew large over the years, with six children, 33 grandchildren and 57 great‑grandchildren cited in county histories. Crismon Road recognizes the Crismon family, members of the so‑called “Mesa Party” of Mormon families who migrated from Idaho and Utah in the 19th century; the family’s farms and ranching operations continued until the 1960s, when they ceased raising crops and cattle.
Names tied to recreation, midcentury development and retirement communities also appear on Valley maps. Country Club Drive traces its name back to the Mesa Country Club, which opened in 1948; the street went through several name changes before adopting the designation that reflects the golf club’s presence. Del Webb Boulevard commemorates Del E. Webb, the developer who founded Sun City in 1960 and helped popularize the retirement community model that became a national phenomenon. Those mid‑20th century projects reshaped large swaths of the Valley and left a permanent imprint on local street names.
Ranching and early economic themes surface in other road names. Dobson Road is named for Cliff Dobson, who co‑owned the Baseline Cattle Company and Sheep Springs Sheep Company in the early 1900s — a reminder of the era when Arizona’s economy was commonly described by its “five C’s”: cattle, copper, cotton, citrus and climate. Dunlap Avenue takes its name from John T. Dunlap, who served as Phoenix mayor from 1904‑05; Dunlap owned land east of Seventh Street and south of Alice Avenue that was later subdivided, and the street continues westward as Olive Avenue at 43rd Avenue. Finally, Dysart Road remembers Nathaniel Martin Dysart, a rancher who donated land for a one‑room Dysart School in then‑rural land near Surprise in 1920 and remained on the school board until his death in 1955.
Together, these 15 names offer a cross‑section of the Valley’s evolution — from surveying lines and homestead classrooms to irrigation projects, ranching enterprises, public institutions and large‑scale residential development. Each road name recorded here ties a stretch of asphalt to a person, place or project that helped shape the communities drivers move through every day.
