What it means
Carefree Highway is where Scottsdale stops. The road runs east-west along the city’s northern limit, with Scottsdale on the south side and the Town of Carefree on the north, and when Scottsdale Road crosses it the name changes to Tom Darlington Drive and the boulder piles start. Locals use it as a boundary word: “north of Carefree Highway” means out of the city, into the high desert of Desert Mountain, Cave Creek and the Tonto National Forest.
It is also the far north’s only real east-west road, which is why a street serving a town of a few thousand carries so much traffic. From Scottsdale Road it runs west past Cave Creek Road, the Ben Avery shooting range and Interstate 17 to Lake Pleasant, and beyond I-17 it is officially State Route 74, continuing as the Lake Pleasant and Morristown highways to US 60 near Wickenburg. And it is a song. Gordon Lightfoot’s “Carefree Highway” went to No. 10 in 1974 because he saw the sign.
Where you’ll meet it
Directions to the Boulders, Carefree, Cave Creek and Lake Pleasant; the top edge of every Scottsdale map; the north end of Pima Road country; and classic-rock radio.
Where the word came from
The highway is named for the town, and the town was named by its developers. In the mid-1950s K.T. Palmer and Tom Darlington bought a stretch of high desert north of Scottsdale and laid out a community sold on serenity, with street names like Easy Street and Ho Hum Road; their company was the Carefree Development Corporation, and ADOT’s history of the north Valley’s cross streets credits it with the name. The road that reached the new town from Interstate 17 became Carefree Highway in the same spirit: a promise, not a description.
The state’s part of it came together in the early 1960s. The Arizona highway commission assigned State Route 74 on December 15, 1961, as a planned route from US 60 south of Wickenburg east to I-17, and the 30-mile road opened in 1964, carrying three names along the way: Morristown-New River Highway, Lake Pleasant Highway and, approaching the interstate, Carefree Highway. The 12 miles east of I-17 to Scottsdale Road were never part of SR 74 proper; a short connector between the two was signed as “temporary” route SR 74T in 1974 and only lost the T on October 18, 1989.
The song came from the sign. Gordon Lightfoot told interviewers he was driving from Flagstaff to Phoenix, passed a sign pointing to Carefree Highway, and thought it would make a title. He wrote it down and, by his account, it sat in his suitcase for eight months before he set it to a tune about a man trying to outrun the memory of a woman named Ann. Recorded in Toronto in November 1973, released in August 1974 as the second single from the album Sundown, it reached No. 10 on the Billboard Hot 100 and spent a week at No. 1 on the Easy Listening chart that October. ADOT, which owns the sign, has been dining out on it ever since.
What it is not
It is not a highway in the freeway sense: four lanes, then two, with stoplights at Cave Creek Road and Scottsdale Road. And it is not in Carefree. The town sits north of it; the road is the line.
The fine print
Wikipedia’s arterial survey puts the whole road at 42 miles from Lake Pleasant Parkway in Peoria to Scottsdale Road, all of it a principal arterial on the National Highway System even though only the western 30 miles carry a state route number. East of I-17 the ownership is a patchwork of Phoenix, Maricopa County, Cave Creek, Carefree and Scottsdale, which is why the pavement and the speed limit change without warning. The highway follows Phoenix’s northern city limit through the Desert View village, then the south edge of Cave Creek, dips briefly into that town at Cave Creek Road, and finishes as a two-lane road with Scottsdale on the right and Carefree on the left.
The Scottsdale Road corner is the one visitors see: the Boulders resort on the southwest, the old El Pedregal marketplace site, and the sign announcing Tom Darlington Drive. Scottsdale’s city limit here dates from the annexations of the early 1980s that carried the city to the national forest, and the highway has been its northern fence line since.
The Lightfoot details are better documented than most road lore because he told the story often, with small variations: the ADOT blog version has the note nearly left in a glove compartment rather than a suitcase. What is not documented is which sign. The I-17 interchange sign is the one people photograph, but a man driving down from Flagstaff on the interstate would have seen the exit sign for “Carefree Hwy,” and that is probably the one. The town of Carefree, for its part, got a song it never asked for and a highway named for it that it mostly watches go by.
