Collins Avenue, partly co-signed State Road A1A, is a major thoroughfare in South Florida, United States. The road runs parallel to the Atlantic Ocean in Miami Beach, Florida, one block west. It also runs through the cities of Surfside and Sunny Isles Beach to the north. Collins Avenue was named for John S. Collins, a developer who, in 1913, completed Miami’s first bridge, Collins Bridge, connecting Miami Beach to the mainland across Biscayne Bay.
