The viaduct carries approximately 110,000 vehicles per day just south of the mid-town ramps. Of this amount, approximately 17,000 vehicles enter or exit downtown at Columbia and Seneca streets, and 33,000 exit or enter at Elliott and Western avenues toward Belltown, Uptown, and neighborhoods along the 15th Avenue and Elliott Avenue corridor. The remaining 60,000 vehicles continue north through the Battery Street Tunnel, either exiting in the South Lake Union/Queen Anne area or continuing north across the Ship Canal.
