Tulsa's ninth annual 918 Day runs Sept. 18 and Sept. 19 with a Route 66 centennial theme tying together events across the city.

The two-day lineup includes Mayor Monroe Nichols' "Monroe On the Go" tour, a passport challenge hitting a dozen landmarks along the Mother Road and a handmade market at Veterans Park. The celebration launched in 2018, with the date playing off Tulsa's 918 area code.

Nichols kicks off the weekend Friday by traveling to city facilities, schools, businesses and community organizations along Route 66, according to the city of Tulsa. Residents can follow his stops on Facebook and Instagram at @MonroeForTulsa.

The main event lands Saturday. The second annual 918 Day Passport Challenge runs 10 a.m. to 6 p.m. with 12 stops stretching from east Tulsa to the Arkansas River and southwest Tulsa. Participants pick up a passport card at any stop or print one from the city's 918 Day website, then collect stamps at each location. Cards, stamps and promotional items are available while supplies last.

Stops include Tulsa Fire Station 66 at 14333 E. 11th St., the Route 66 Interpretive Plaza, the Oklahoma Route 66 Association headquarters, Circle Cinema at 10 S. Lewis Ave., the Sinclair Service Station at Rossi Brothers Company, the Meadow Gold Neon Sign, the Blue Dome, Cyrus Avery Centennial Plaza and Howard Park at 2510 Southwest Blvd., according to TulsaKids.

Howard Park is listed as the future home of a planned 66-foot-tall dinosaur statue.

The Oklahoma Route 66 Commission approved $225,000 toward the project, which carries an estimated total cost of $536,000, according to Route 66 News. The 7,000-pound fiberglass structure is being built by the same company behind the "Cowboy Bob" and "Meadow Gold Mack" statues on Route 66, News On 6 reported. The Tulsa Parks and Recreation Board adopted the project concept in September 2025, according to board meeting minutes, with funding extending through 2027.

Circle Cinema, another passport stop, hosts the Oklahoma premiere of the documentary "Route 66: The Main Street of America" on the evening of Sept. 18. Director John Paget and Route 66 historian Michael Wallis will attend. Tickets are $50 for members and $66 for non-members. Wallis called Paget's earlier Route 66 documentary the best ever made on the Mother Road and said in an Aug. 21 Tulsa Today announcement, "I can't wait to see his new film for the Route 66 Centennial."

A bonus 13th passport stop doubles as its own event: the second annual Tulsa Parks Handmade Market at Veterans Park, 1028 E. 6th St., runs 10 a.m. to 4 p.m. Saturday. Dozens of local vendors will sell handmade goods and food.

All 13 stops sit along Route 66.
