The Causeway is a toll road, owned and operated by Miami-Dade County. Automobiles traveling southbound from Miami pay a toll of US$1.50 as of March 2009; northbound traffic is not charged any toll. Various pre-paid plans using a 'C-Pass' transponder are available.
Also known as (unsigned<!--i think it's actually signed here-->) State Road 913, the causeway’s northbound continuation is a pair of flyover ramps to northbound Interstate 95 (unsigned SR 9A) and southbound Brickell Avenue (US 1/unsigned SR 5); the southbound continuation is Crandon Boulevard, which extends roughly five miles through the center of Key Biscayne, terminating near the Cape Florida Lighthouse in Bill Baggs Cape Florida State Park.
