Prepare for Boise road closures, detours and delays on Ironman Saturday

June 6, 2014 

The Ironman 70.3 Boise is Saturday (and so is the one-mile Capitol Classic running race in Downtown Boise). The Ironman 70.3 begins with a 1.2-mile swim at Lucky Peak Reservoir. Racers will then hit the bicycle course before finishing the race with a half-marathon run on the Greenbelt to Julia Davis Park.

The race will result in a number of road closures and other traffic restrictions and detours throughout the day. Below is information from the Ada County Highway District and Ironman 70.3 Boise organizers:

The ACHD is working with Ironman 70.3 Boise organizers, along with Boise Police, the Ada County Sheriff’s Office, the Idaho Transportation Department and others to prepare for the road closures necessary to make the event possible. Citizens not involved in the Ironman event are urged to prepare and take alternate routes. Detour routes will be in place for the closures, and drivers should use caution. Local law enforcement and event volunteers will be stationed along the course and will help residents get in and out of businesses and residences during the event.

Along the cycling course, there will be impacts to areas including Columbia Village, South Eisenman Road, Bown Way, Warm Springs Avenue, Boise Avenue and Bergeson Street and Federal Way where cyclists will be sharing the road with vehicles.
