In many cities, the size of each city block is
standardized. There may be 8 or 10 blocks per mile, for example, in the downtown area. In many suburbs, or other areas, you will find places where you would expect there to be a cross-street, but it was omitted, leading to an extra-long walk or drive before encountering a cross street. This is described as a "big block," so
you know what to expect when you are
in the area.
Get off the bus at the
hospital. You'll need to walk three big blocks south until you get to Elk Grove Avenue, my street.
I love
walking in Rio, because it has such big blocks, full of nice buildings!
