ATLANTIC PACIFIC HIGHWAY extends from New York city to Los Angeles and San Diego, Calif., and is about 3,000m. long. In 1928 it was hard and paved for a large part of the distance from New York to Portsmouth, O., paved the full breadth of Illinois, and hard or paved across California; for the rest of its length it was partly unimproved. Spanning the continent as it does, the Atlantic Pacific highway probably em braces a greater variety of scenes and climate than any other American thoroughfare. Philadelphia, Wilmington, Baltimore, Washington, Covington, Charleston, Cincinnati, St. Louis, Wichita, Santa Rosa and Phoenix are among the cities included in its course.
PACIFIC HIGHWAY runs from Chicago, I11., to Yellowstone Park, and is about 1,562m. in length. In 1928 it was paved as far as Dubuque, Ia., improved or paved to Sioux Falls, S.D., and mostly improved across Wyo ming. Beginning close to the western shore of Lake Michigan, it passes through the low-lying farm country and touches upon the picturesque Black Hills of South Dakota, in which is sit uated Wind Cave National park.
The Shoshone district, noted for its ranch resorts, and the Iowa lake region also lie in its path. The natural bridge of Wyoming and Jackson Hole, famous as a hunting resort, are accessible from some of its many branches. Rockford, Dubuque, Mason City, Sioux Falls, Douglas and Casper are among the important cities that lie along this route.
