At the dawn of the 20th century, Newport reached a pinnacle of success as three impressive civic buildings came to symbolize its prominent regional and Vermont position: the Goodrich Memorial Library, which opened on September 1, 1899 with an inventory of 6,500 books, electricity, and running water; the Orleans County Courthouse, built in 1886 of all local materials; and the Federal Building, c.1904, which housed federal offices, the U.S. Post Office, and the federal courthouse. All three remain standing and are largely unchanged. In the early 1900's, the invention of the automobile and its rising popularity had perhaps the greatest impact on Newport, as buildings adapted and hotels converted liveries and stables into automobile garages. Main Street was paved in 1917 to better handle this new form of transportation, and by 1930 more than 4,000 motor vehicles traveled it each day during the summer months as Newport remained a popular resort destination.
