Named for a mountain man who likely never saw the town
Williams takes its name from Bill Williams Mountain, the peak that rises just south of downtown, which was in turn named for William Sherley "Old Bill" Williams, an early-1800s trapper and mountain man who worked the region decades before the town existed. The naming pattern -- town named after mountain, mountain named after person -- means the town's namesake predates its own founding by several decades.
An 1881 railroad town
Williams was established in 1881 as the Atlantic and Pacific Railroad (a predecessor later absorbed into the Atchison, Topeka and Santa Fe Railway) pushed its line across northern Arizona. Like many towns along that route, Williams existed first as a railroad camp and depot point, with the surrounding ponderosa pine forest supplying a timber industry that, alongside ranching, anchored the local economy for decades.
The Grand Canyon Railway and the Fray Marcos Hotel
In 1901, a rail spur opened connecting Williams to the South Rim of the Grand Canyon, and that same year the Fred Harvey Company began developing a hotel property in Williams -- part of the Harvey House chain that served rail passengers across the Southwest. That hotel, the Fray Marcos, opened to the public in 1908. The hotel and the adjoining depot became one of the most architecturally significant buildings in what is now the Williams Historic Business District, listed on the National Register of Historic Places. The Grand Canyon Railway itself stopped regular service in the 1960s as automobile travel took over, but was revived in 1989 and still operates a passenger train between Williams and the Grand Canyon's South Rim today -- see our Grand Canyon Railway guide for how a modern ride compares to the historic original.
Route 66 becomes Main Street
As highway travel grew through the early and mid-20th century, U.S. Route 66 ran directly through Williams, and the town's downtown grew up around that through traffic -- motels, diners, and gas stations lining what is now Grand Canyon Boulevard and Railroad Avenue. This is the era that shaped much of what visitors associate with Williams today, and our historic downtown walking guide covers the specific storefronts and buildings from this period in more detail than fits here.
October 1984: the interstate arrives
Interstate 40 was built to bypass most of the towns along old Route 66, and Williams held out longer than any other town on the route. When I-40 finally opened its bypass around Williams in October 1984, it marked -- as the town's own tourism materials note -- the last stretch of the original Route 66 alignment to be superseded by the interstate. That distinction is central to how Williams presents itself today: not just another old Route 66 town, but specifically the last one. Our Route 66 guide goes further into what remains of the original alignment through town.
What the history means for a visit today
Because Williams' downtown reflects both the railroad era and the Route 66 era rather than one or the other, a walk through it reads differently depending on what you're looking for -- railroad and Harvey House architecture on one hand, mid-century highway culture (neon signs, classic motels) on the other. Both layers are still visible within a few blocks of each other, which is part of what distinguishes Williams from towns that lost one era or the other to demolition or decline.
