The California Department of Transportation will suspend service of the J-Mack Ferry on Sunday morning to perform routine preventive maintenance. The J-Mack is scheduled to be closed from 6 a.m. to noon.
Caltrans will change the underwater cable that guides the ferry. It's routine preventive maintenance which must be done periodically, according to Caltrans.
The J-Mack, also known as the Steamboat Slough Ferry, provides around-the-clock service on Highway 220 between Ryer Island in Solano County and Grand Island in Sacramento County.
Motorists are advised to use the Real McCoy Ferry, also known as the Cache Slough Ferry, along Highway 84 in Rio Vista.
