System links

The Pennsylvania Department of Transportation (PennDOT) is responsible for the establishment and classification of a state highway network which includes interstate highways, U.S. highways, and state routes. U.S. and Interstate highways are classified as state routes in Pennsylvania. The Commonwealth of Pennsylvania established the Location Referencing System (LRS) in 1987, which registers all numbered routes in Pennsylvania as SR-X. A state route would be SR 39, a US Route would be SR 22, and an interstate route would be SR 80. However, routes which are numbered between 0000 and 0999 are classified as Traffic Routes, which are abbreviated as PA 39, US 22, and I-80, instead.[1] There are also four-digit numbers for various "state roads" over which PennDOT has jurisdiction, but those numbers are not displayed on the roads, except in rural areas, where they are posted with index-card-sized small signs. Google Maps, however, has replaced street names in the Philadelphia area with those 4-digit numbers, which are not used by locals. In cities, these numbers are not even displayed or posted on the streets. Instead, those streets are known by the names on the street signs. The 4-digit numbers are obscure and not in use outside of PennDOT itself.

History

In 1911, when the Sproul Road Bill was passed, a large number of Legislative Routes (LR) were assigned. These were the primary internal numbering until the present Location Referencing System was adopted in 1987. See also list of Legislative Routes in Pennsylvania.

Signed Traffic Route numbers from 1 to 12 were first assigned in 1924[2] to several of the national auto trails:[3]


Soon more numbers were assigned, including three-digit numbers for branches, like Pennsylvania Route 272 from Pennsylvania Route 72. The United States Numbered Highways were assigned in late 1926, and in 1928 State Routes concurrent with U.S. Routes were removed, while those that conflicted with U.S. Routes were assigned new numbers. The establishment of the Interstate Highway System in 1959 resulted in a small renumbering in 1961.

Since Pennsylvania first introduced numbered traffic routes in 1924, a keystone shape has been used, in reference to Pennsylvania being the "Keystone State". The signs originally said "Penna" (a common abbreviation for Pennsylvania at the time), followed by the route number in block-style numbering in a keystone cutout. In the mid 1950s, the signs were modified to have "PA" instead of "Penna", with the lone exception being the mainline Pennsylvania Turnpike (which continues to use "Penna" today for both the mainline, the Northeast Extension, and the Pennsylvania Turnpike Commission logo); additionally, the numbers were made more round and the signs were made larger in order to be more legible while driving, and the keystone shape itself remained a cutout. By the late 1960s, as U.S. Routes were beginning to be made on rectangular cutouts with the U.S.-style shield painted onto them instead of the shield cutout in most states outside of California, the same was done with the keystone. The state initials were removed altogether and while the numbers remained rounded, were standardized into Highway Gothic, which was becoming the standard for the Interstate Highway System. Most of the 1950s vintage signs were replaced with the newer rectangular cutout with the painted-on keystone by the early 1970s, though a very few remain in scattered places on non-decommissioned roads. Pennsylvania has used the painted-on keystone signs since.
