Card Sound Bridge

Card Sound Bridge is a high-rise tollcauseway connecting southern Miami-Dade County and northern Monroe County. It is one of only two ways that motorists can leave or enter the Florida Keys (the other is U.S. Route 1). The toll for two-axle automobiles is $2.13 for two-axle vehicles: cars, pickup trucks or motorcycles. $4.08 for three axles. $1.35 per each additional axle if paid via SunPass. The prior toll plaza was demolished during Hurricane Matthew and has been replaced with a toll-by-plate plaza. The toll fee will be charged by plate automatically and sent via the mail to the address on the vehicle registration. The cashless all-electronic tolling system replaced the previous staffed toll booth on October 20, 2018. The toll fee is waived upon evacuating the Keys for hurricanes or in instances in which US 1 is impassable.
