Straight Line Diagrams

The New Jersey Department of Transportation (NJDOT) 2015 Straight Line Diagrams (SLDs) are a way to view roadways in a line format. The SLD network presents approximately 12,528 miles of State (Interstate, US and NJ numbered roads), National Highway System (NHS), Surface Transportation Program (STP) and all County routes.

Please continue to submit your feedback and proposed changes to the SLDs by using the corrections/suggestions form (pdf).
