DEDICATE THE DUNES HIGHWAY
    The Dunes Highway, transcontinental route through the famous dunes region, was officially opened yesterday by the mayors of northern Indiana cities, highway departments of Indiana, Michigan and Illinois, and county officials of Lake and Porter counties.
    An automobile parade over the new road from Gary to Baileytown where ceremonies were held, and from that historic place to Michigan City for the banquet comprised the day's program.
    Led by the Gary municipal band the parade started from the Gary Commercial club and drove to Baileytown where a marker was placed.  The line of 500 automobiles then continued to Michigan City.  J. S. Norton, president of the Lake County Good Roads Association and John D. Williams, director of the Indiana Highway Commission, made short addresses at the Baileytown ceremonial.
    At the banquet addresses were given by Earl Crawford of the Indiana Highway Commission; Frank D. Rogers, of the Michigan Commission; W. H. Loutit, president of the West Michigan Pike Association; W. P. Gleason, president of the Gary Park Board and the National Dunes Park Association; F. T. Vosjell, of Chicago, district engineer of the United States Bureau of Public Roads, and H. J. Gary, manager of the Michigan Tourist and Resort Association.
    The new highway consists of twenty-four miles of concrete road through the heart of the duneland and borders the proposed new Indiana Dunes Park.  The highway reduces the distance from Gary to Michigan City by ten miles and its completion is one of the big feats of the Indiana Highway Commission.
