 Plan ahead for detours. From mid-July through early September, the Idaho Transportation Department will close 10th Avenue intermittently under I-84. Visit itdprojects.idaho.gov for more information. On the eastbound lanes of the freeway, congested traffic starts at Northside, continues over to 11th. Karcher is very busy between Middleton Road and the boulevard, and Garrity's getting busy between 39th and Stam Lane.
