Why McLean's streetscape survived
McLean was founded in 1902 as a railroad townsite on the new Choctaw, Oklahoma & Texas Railroad (later absorbed into the Rock Island system) and grew quickly as a regional agricultural and ranching service center. The arrival of Route 66 in 1926 added a second commercial economy — the gas stations, motor courts, cafes, and tourist services that the new highway demanded — and McLean prospered through the 1930s and 1940s as one of the busier small commercial centers on the Texas Route 66 stretch. World War II brought a German POW camp to the outskirts of town (Camp McLean, 1943-1945), which added wartime economic activity and is itself a small historical curiosity now interpreted at one of the district markers.
The post-war Route 66 era through the 1950s and early 1960s was McLean's commercial peak. The town supported multiple motels, cafes, gas stations, garages, and the full range of services a major U.S. highway brought to a Panhandle small town. The decline began with Interstate 40 construction in the 1960s and continued through the gradual decommissioning of Route 66 — but the I-40 bypass of McLean was the last bypass on the Texas Panhandle stretch, not completed until 1984. That meant nearly two extra decades of Route 66 commercial activity compared to towns like Shamrock and Amarillo, which were bypassed earlier.
The late bypass had the paradoxical effect of preserving McLean's original streetscape better than richer towns'. By the time the bypass arrived, McLean was already economically diminished and there was no urban-renewal pressure to demolish the original Route 66 buildings or modernize the storefronts. Buildings sat instead of being replaced. When historic preservation interest revived in the 1990s, McLean still had a remarkably intact stock of 1920s-1950s architecture, and the surviving structures became the basis for the current historic district designation. The district was added to the National Register of Historic Places in the 1990s as part of broader Texas Route 66 listings.
