The change applies only to mostly rural and suburban interstates — not U.S. routes, state routes or other multi-lane divided highways — where currently the speed limits are split between 65 mph and 55 mph.
ODOT officials say they don’t know how many signs will have to be changed, but they hope to change them all in one day.
