Limited-Access Highway Classification Codes

The Bureau of the Census (U.S. Census Bureau) publishes this notice to announce the upcoming change in the classification of limited-access highways in the Census Bureau's Master Address File/ Topologically Integrated Referencing and Encoding (MAF/TIGER) System. The change assigns all limited-access highways a MAF/TIGER Feature Classification Code (MTFCC) of S1100 (Primary Roads). Previously, the classification code for limited-access highways was either S1100 (Primary Roads) or S1200 (Secondary Roads).
