The Pikes Peak Ocean to Ocean Highway was one of America's first big roads that stretched all the way across the country. It connected New York City on the east coast to Los Angeles on the west coast. This highway competed with other famous roads like the Lincoln Highway and the National Old Trails Road. You could spot its route markers, which said PP-OO.

Building a Cross-Country Road

The idea for this highway began in Colorado Springs, Colorado. Local towns and cities helped build it by giving money and improving their roads. This was a way to encourage travel and business.

The plan became official on March 18, 1914. This happened at a meeting in St. Joseph, Missouri, with leaders from state and national road departments. The entire highway was finished by 1924.

Why the Route Changed

The original plan for the highway was to go from Washington, D.C. to San Francisco. However, there was already a good road called the National Old Trails Road in the eastern part of the country. This made New York City a better starting point. Also, to compete with the Lincoln Highway and find an easier path south, the end point was changed to Los Angeles.

Colorado's Two Paths

The highway had two different routes through Colorado. Both started in Colorado Springs, Colorado and ended in Grand Junction, Colorado.
