the wooden bridges in northern Key Largo—including Card Sound. A 1944 fire seriously damaged Card Sound's drawbridge, which was subsequently removed to prevent its further use; a 1947 hurricane and additional fires caused Monroe County officials to remove the Card Sound Bridge completely. The return of Card Sound Bridge In the two decades after the removal of the Card Sound wooden drawbridge, various schemes to increase access between the Keys and mainland Florida came and went. A -long bridge from Cape Sable to No Name Key did not succeed due to the establishment of Everglades National Park; a monorail from Miami to Cape Sable to Key West met the same fate. In the 1960s a plan to connect Key Biscayne to northern Key Largo by way of Elliott Key almost took root as officials from Dade and Monroe Counties differed on the division of toll revenues. In the meantime, the United States Department of the Interior started purchasing land in Biscayne Bay with an eye toward creating a new National Park. The 1968 formation of Biscayne National Monument (which became Biscayne National Park in 1980) hastened the demise of the "Islandia plan" (named after a sparsely populated municipality on Elliott Key), but one component of the proposal survived: a new -high causeway to be the new Card Sound Bridge. The new causeway was completed and open to traffic in 1969. Card Sound Road became State Road 905A, a FDOT designation which was modified to SR S-905A in the mid-1970s. In the early 1980s, Card Sound Road was transferred to county maintenance in both Dade and Monroe Counties, although the stretch on northern Key Largo between Ocean Reef Club and US 1 is still "State Road 905" in Monroe County ordinances passed in the 2000s. Actually, County Road 905A has its northern terminus at an intersection with US 1 in Florida City and its southern terminus at County Road 905 in northern Key Largo five miles (8 km) to the east of Card Sound Bridge (CR 905 continues southwestward eight miles (13 km) until it joins US 1). Both CR 905 and 905A on Key Largo still show FDOT signs indicating State routes on their shoulders. As of 2016, Card Sound Bridge is traversed by 3500 vehicles daily.
