BLVDS is an acronym for 'Boulevards, ' which are wide, multi-lane roads that are typically found in cities and towns. They are usually lined with trees and other vegetation, and often have a median strip in the middle. Aves (4 letters) is another term for boulevards, while RDS (3 letters) and Sts (3 letters) are abbreviations for roads and streets, respectively. All three terms refer to wide, multi-lane roads that are typically found in urban areas.
