williamsburg bridge - lower east side (entrance: clinton & delancey streets)/brooklyn - map it here [L]
The Williamsburg Bridge opened in 1903. Immigrants who were living in the crowded Lower East Side began crossing the bridge to fill tenements directly across the river. In the 1990's, artists who couldn't afford the East Village also crossed the river. And so today, Williamsburg is known as a hipster haven (Northside) as well as a Hasidic and Hispanic neighborhood (Southside).
As it is farthest north, compared to the Manhattan and Brooklyn brides, crossing the Williamsburg Bridge provides you with a closer view of Midtown Manhattan.
A warning though if you plan the crossing: you will be overwhelmed by all the of pink around you.
It is very pink.
