The Pennsylvania State Route Numbering System
Random Numbers Assigned to Pennsylvania State Routes

Route numbers that do not fit into any apparent numbering scheme are listed below. In many cases, a randomly assigned number was assigned in a nonrandom manner to another route in the past. Most randomly assigned numbers remain today. Most of the randomly assigned routes designated before the Interstate highway system was created run east-west if the number is odd and north-south if even (like the original 1928 system), whereas later routes have the directions reversed (like the Interstate system).
