Florida State Road 856
Highway in Florida
State Road 856 (SR 856), also known as the William Lehman Causeway, is a 1.704-mile-long (2.742 km) causeway connecting Biscayne Boulevard (U.S. Route 1/SR 5) in Aventura and Collins Avenue (SR A1A) in Sunny Isles Beach, Florida.
SR 856 is a limited access highway between the two termini. Pedestrians are prohibited, but (as part of a pilot project that also includes the Pineda Causeway) the shoulder is marked as a bike lane east of the Country Club Drives interchange (cyclists must exit here and use other roads to continue west).[2][3]
