The Idaho Transportation Board has voted unanimously to approve 80 mph speed limits for southern Idaho freeway stretches on I-84, I-86 and I-15 that now are 75 mph, but only after a long discussion of questions about the changes and with the condition that the new limits be reviewed in one year. The board’s resolution, approved this afternoon during its meeting in Coeur d’Alene, takes note of comments received from the Idaho Trucking Association and AAA of Idaho, and also notes that the new state law allowing the higher speeds requires the board’s concurrence for them to be imposed. The ITD's staff had recommended the changes, after traffic studies showed motorists already are traveling that fast on those routes.
