ITD plans detours, traffic changes for Ironman triathlon competition Saturday
BOISE - For the Boise Ironman 70.3, coming up on Saturday (June 11), ITD is planning a different approach to restrictions on Idaho 21 in order to maintain access for the traveling public.
More than 1,500 participants are expected for the event. This is the fourth year of a five-year agreement between the Ironman organizers and the city of Boise.
There are no “hard” or complete closures planned without detour routes in place. Idaho 21 has been completely closed to all but competion cyclists in years past, but this year one lane will be maintained for traffic to get through. The lane closest to the cyclists will be closed, but the other lane in that area will remain open, controlled by flaggers. Here are the details for Saturday's event:
Idaho 21
12:20 p.m. to 2:20 p.m. – Idaho 21 will be reduced to one lane between S. Surprise Way and Diversion Dam. Flaggers will allow traffic through one direction at a time.
12:30 p.m. to 5:30 p.m. – Idaho 21 between Federal Way and S. Surprise Way will be closed. Traffic will be detoured through Federal Way, E. Amity Road, and S. Surprise Way. On the closed segment of Idaho 21 (Federal Way to S. Surprise Way), people that live off Alta Vista Ridge Court will still have access in and out of their homes
5:30 p.m. - Based on past years, the last bicyclist is anticipated to move through by this time. Traffic flagging will end as soon as last rider leaves Idaho 21.
5:45 p.m. – The highway returns to normal operations.
U.S. 20/26
8 a.m. to 11 p.m. – Front Street will be closed between Capitol Boulevard and 9th Street. Front Street will be detoured north on Capitol Blvd., west on Idaho Street, then south on 9th Street. This area will be the first-aid medical station, and the command center for law enforcement during the event.
Noon to 11 p.m. – Myrtle Street will be closed between 11th Street and Capitol Boulevard. Myrtle Street will be detoured north on 11th Street, east on Main Street, then south on 3rd Street.
I-84 Eisenman Interchange
12:40 p.m. to 5 p.m. - Interchange ramps will be closed and traffic detoured to the Gowen Interchange. The closure of the Eisenman Interchange allows the bicycling portion of the competition to be rerouted away from the Gowen Interchange and Idaho 21/Federal Way intersection, which are more heavily used by motorists. The interchange is expected to reopen as soon as the last cyclist gets through the area on the return trip.
