Speed limit increases for drivers going down Lewiston Hill

LEWISTON, ID - Motorists approaching Lewiston from the north on U.S. 95 might have noticed a new speed limit Friday.

Signs that previously limited travel to 55 miles per hour on the long grade down into Lewiston were replaced, reflecting an Idaho Transportation Department decision to increase the speed limit to 60 miles per hour to improve safety and traffic flow.

A recent ITD traffic study indicated approximately 85% of motorists on that segment of U.S. 95 already travel at 60 miles per hour. According to research, setting a speed limit according to that 85th percentile produces the fewest crashes.
