WINONA Minn. — The narrowing of U.S. Highway 14 up Stockton Hill on the Winona side was a one-day project, said state transportation spokesperson Mike Doughery. A crew was tarring caps on pilings that hold back new retaining walls on steepest sections of the highway. Pilot cars led motorists in single columns between Knopp Valley in Winona and the 1110-degree turn near the summit at Seminary Road.
