This link leads to a navigable view of Fort Lauderdale taken from a satellite. All have bridges over the Intracoastal Waterway to the beaches except, strangely, Broward. In between the named boulevards are the numbered streets that are consecutively arranged according to the following easy system. There is the odd exception, but this rule will help you in most instances. Andrews Avenue divides the city between the east and west, and Broward Boulevard divides the north and south.
Streets run east and west while avenues run north and south.
If an address is in the NE quadrant, it is north of Broward Boulevard and east of Andrews Avenue.
