Irish-born engineer and surveyor Christopher Colles produced what is considered the first road map or guide book of the U.S. It uses a format familiar to modern travelers with each plate consisting of two to three strip maps arranged side by side, covering approximately twelve miles. Colles began this work in 1789 but ended the project in 1792 because relatively few people purchased subscriptions for the books. But in that time, he compiled an atlas covering approximately 1,000 miles from Albany, New York, to Williamsburg, Virginia. The book is invaluable for understanding the developing road network in the newly formed United States.
