This article covers the non-directionally labeled numbered east-west streets in the New York City borough of Brooklyn between and including 1st Street and 101st Street. Major streets have their own linked articles; minor streets are discussed here. Most are offset by about 40 degrees from true east-west, that is they run southeast-northwest, but by local convention they are called east-west.
With avenues numbered from 1 to 28, they form a street grid. While similar to Manhattan's grid, this Brooklyn grid does not have strict rules of traffic direction based on whether a street number is odd or even. This grid starts with 1st Street in Park Slope south of Garfield Place and ends with 101st Street just north of Shore Road and the Belt Parkway in Bay Ridge.
A separate grid of "East" streets (East 1st through East 108th Streets) lie east of Dahill Road and run approximately north-south.
