State Route 220 (SR 220) is a state highway in the U.S. state of California, defined to run between State Route 84 and State Route 160 on Ryer Island in the Sacramento–San Joaquin River Delta. At the eastern end of Ryer Island, the road crosses Steamboat Slough on the Howard Landing Ferry, a cable ferry.
State Route 220 is defined under the California Streets and Highway Code to run east from State Route 84 on Ryer Island in Solano County to State Route 160 in Sacramento County.[2] The route includes the toll-free Howard Landing Ferry, where the cable-drawn vessel J-Mack takes vehicles across Steamboat Slough.[3] Both the Howard Landing Ferry and the Ryer Island Ferry along State Route 84 are the only state-run ferries, and there are no plans to replace them with bridges due to the low traffic numbers around Ryer Island,[4] [5] The only road bridge connecting Ryer Island is on its north side, which results in longer commutes for residents if one or both ferries shutdown.[6]
