Strategic Regional Arterial Resources

Introduction

The Strategic Regional Arterial (SRA) system is intended to carry larger volumes of traffic at higher speeds as a complement to the region's expressway system. Efforts are made to preserve the level of service on these roadways through appropriate access and traffic signal locations and spacing. To ensure a high level of service for traffic on the SRA system, the Illinois Department of Transportation maintains more restrictive criteria in determining the need for and spacing of traffic signals and access points.

As CMAP develops small-area traffic projections for implementing agencies, we also check whether the location in question is on a Strategic Regional Arterial and direct the applicant to review the relevent SRA report for its recommendations.

SRA Map

Download or view the .pdf format map (view at 100% or 125% to read the numbers more easily) to identify which of the region's roadways are included in the SRA system, or have been proposed for SRA status. The numbers listed near the road name lables (for example, SRA 514) indicate what SRA study report includes this roadway. Some SRA studies are still underway, with reports not yet available.
