Access to one of Historic Route 66's most iconic towns will be limited for nearly a year while bridges along Interstate 40 are improved.

With that in mind, the Arizona Department of Transportation is working with the town of Seligman to ensure Northern Arizona travelers know they still can reach the Snow-Cap Drive-In and other attractions in town.

Exit 121, which takes drivers from I-40 to the west side of Seligman, closed earlier this month so decks on three bridges could be replaced. The bridges are between 40 and 50 years old, ADOT said in a news release, and the 10-month construction project will provide a smoother ride for Seligman visitors.

Exit 123, which leads to Seligman's east side, will remain open while the $4.3 million project is underway, ADOT said. From there, visitors can easily reach the Snow-Cap, Westside Lilo's Café and Angel Delgadillo's barbershop, along with other Seligman destinations. Signs on I-40 will direct travelers to Exit 123 during the project, ADOT said.

Seligman also makes an excellent starting point for a trip down Route 66 to Kingman. That scenic drive passes Grand Canyon Caverns, one of Arizona's best-known cave systems.
