Corridor sketch initiative

Corridor sketch summaries describe the functionality and features of our state highways. Each summary has information that guides highway improvements.

The Corridor Sketch Status brochure (pdf 726 kb) describes the program and its accomplishments.

The User Guide for Corridor Sketch Summaries (pdf 428 kb) provides a brief description of information presented in each summary along with potential strategies to address congested areas of the highway.
