BLVD. CROSSERS is a term used to describe people who cross busy boulevards or streets. The term is composed of three words: AVES (4 letters), RDS (3 letters), and STS (3 letters). AVES stands for 'AVENUES, ' which are wide, important roads that usually run north-south. RDS stands for 'roads, ' which are typically smaller than AVENUES and usually run east-west. STS stands for 'streets, ' which are the smallest of the three and are often residential. BLVD. CROSSERS, then, refers to people who cross these busy boulevards, roads, and streets.
