Both U.S. Route 11 and Interstate 81 pass through the hamlet, connecting it to Watertown to the north and Syracuse to the south. In April 2007, the Town of Cicero redrew the traditional boundaries of Brewerton, moving the eastern line west to Interstate 81, and the southern line northward from Mudmill Road to Orangeport Road. This was done to allow Brewerton to remain eligible for Federal grant money. New housing developments had made Brewerton exceed guidelines for "blighted" areas that allow for improvement funds.
