U.S. Bicycle Route 66 (USBR 66) is a United States Bicycle Route that follows the former U.S. Route 66 (US 66) across the United States. The first section of the route, spanning 358 miles (576 km) between Baxter Springs, Kansas, and St. Louis, Missouri, was designated as USBR 66 in 2018. A second section was designated in 2021 between Santa Monica, California, and the Arizona state line near Needles, California. The Oklahoma section was designated in 2022, bringing the route to over 1,024 miles (1,648 km). The rest of the route remains proposed but not yet designated.

USBR 66 runs along or parallel to former segments of US 66 for most of its route and also incorporates part of Bicycle Route 66, an Adventure Cycling Route Network corridor. At full length, the route is planned to run 2,493 miles (4,012 km) from Los Angeles to Chicago.[2]
The route begins at the Santa Monica Pier in Santa Monica, California. It travels through Los Angeles and the Inland Empire on local streets and part of the Pacific Electric Trail before turning north to follow Interstate 215 and Interstate 15 towards the San Bernardino Mountains. USBR 66 follows Interstate 15 through Cajon Pass and into the high desert, turning east onto Interstate 40 in Barstow, California. It then follows the National Trails Highway to the Arizona state line southeast of Needles, where USBR 66 terminates.[3]
Oklahoma–Missouri segment
Oklahoma
The western end of the route begins at the Texas state line at Texola, Oklahoma. It generally follows the historic alignment of US 66 to Oklahoma City with a notable diversion west of the city. Between Oklahoma City and Kansas the route trends northeast through Tulsa. It continues northeast through the Muscogee Nation and Cherokee Nation Indian reservations. The northeastern end is at the Kansas border near Miami, Oklahoma and Baxter Springs, Kansas.[4]
Kansas

The route begins at the Oklahoma state line south along US 69 Alternate south of Baxter Springs. It proceeds north along US 69 Alternate through downtown Baxter Springs before diverting to Willow Avenue to follow the old alignment of US 66. It turns east onto K-66 at Riverton and crosses the Spring River. In Galena, USBR 66 leaves K-66 and continues northeasterly on Front Street into Missouri.[5][6]
Missouri
USBR 66 follows Highway 66 to Joplin, Missouri. It terminates at the Chain of Rocks Bridge, a pedestrian and bicycle bridge that crosses the Mississippi River into Illinois and carried automobiles as part of US 66.[5]
