WELCOME 1920's Pennsylvania State Road Maps WELCOME

Although Sproul maps continued to be published up to about 1940, beginning in 1925 official tourist maps were issued using plain black & white covers.


1920 MAP OF PENNSYLVANIA SHOWING STATE HIGHWAYS adopted under the Sproul Road Bill approved May 31, 1911, and subsequent amendments and tentative plan of primary system corrected to September 1, 1920. A. Hoen & Co. Baltimore, MD. Size: 17 x 29 inches. This map probably comes from a Smull's Handbook as it is similar to the 1921 map.
1921 MAP OF PENNSYLVANIA SHOWING STATE HIGHWAYS adopted under the Sproul Road Bill .... corrected to December 31, 1921. This map is from a Smull's Handbook for 1921-22 that was apparently reissued in 1922 with this updated map. Size: 17 x 29 inches.
1922 MAP OF PENNSYLVANIA STATE FORESTS, STATE GAME PRESERVES AND REFUGES AND STATE HIGHWAYS, June 1 1922. Base map supplied by courtesy of the State Highway Department, Breuker & Kessler Co. Phila. This map is #373 in Simonetti, and is similar to the 1921 and 1922 maps, but was issued to show state forests and game lands. Size: 18 x 29 inches.
1923 MAP OF PENNSYLVANIA, showing State Forest Monuments, Drives & Views, State Forest Parks, Public Camp Grounds, Fire Observation Towers, District Foresters Headquarters, & Highways. This map appears in a pamphlet titled In Penn's Woods, Bulletin 31 Pennsylvania Department of Forestry, Harrisburg, PA. 1923. The pamphlet is 55 pages with this 13 x 23 inch map attached to the inside front cover. A few towns are named and highways, unidentified and unnumbered, are shown incidently. Back in the 30's, 40's, and 50's, visiting fire observation towers was a big deal, especially for kids.
1924 ROAD MAP OF PENNSYLVANIA SHOWING STATE HIGHWAYS as adopted under the Sproul Road Bill approved May 31, 1911, and subsequent amendments and tentative plan of primary system. Issued by the Department of Highways June 1, 1924. Lith. by A. Hoen & Co., Baltimore. This map is similar to #14 in Simonetti. It shows paved and unpaved roads by color coding, and the type of paving used, i. e. concrete, brick, bituminous asphalt. This large map is a return to the size issued in 1919 and the route color coding makes it an attractive map. Revisions of this map were issued up to around 1940. The 1926 version and beyond removed reference to the Sproul Road Bill. Size: 35 x 57 inches.
1925 MAP SHOWING PENNSYLVANIA STATE HIGHWAY ROUTES 1925. This is the first official tourist road map published by the Highway Department and is dated August 15, 1925. It uses 'old state' route numbers and identifies 13 numbered routes which are printed in red. Main routes are in bold line, secondary routes in thin double line. This map is #419 in Simonetti. Size: 22 x 33 inches, which remained the standard size, more or less.
1926 MAP SHOWING PENNSYLVANIA STATE HIGHWAY ROUTES. This map continued the use of old state route numbers, Route 30 is '1', Route 22 is '3', etc. A total of 15 routes are identified like this in heavy red line, see the Map Image . Governor Gifford Pinchot was a famous conservationist and later became United States Secretary of the Interior. Rural roads thinly coated with tar, oil, and asphalt became known as 'Pinchot Roads', perhaps not a compliment.
1927 MAP SHOWING PENNSYLVANIA STATE HIGHWAY ROUTES. The use of old state routes continued with a total of 19 routes now identified.
1928 MAP SHOWING PENNSYLVANIA STATE HIGHWAY ROUTES 1928. This is the first state road map using modern route numbers. The federal government establishment the US Route system around 1926. East-west routes were (generally) even numbered, i.e. US Routes 30, 22; north-south routes were odd numbered, i.e. US Routes 19, 219. The same idea was used when the Interstate system was developed in the 1950's.
