Suisun City was established in the 1850s. Suisun City's location made it ideal for commerce and transportation during the Gold Rush.
In 1869, the Transcontinental Railroad connected to downtown Suisun City, expanding the regions reach across the nation.
In the 1960s and 1970's Suisun City experienced rapid growth as the San Francisco Bay Area's suburban ring expanded to formerly rural Solano County. Also, in the 1960s Highway 80 was constructed two miles (3 km) outside the city effectively moving commercial traffic away from railways and water conveyance.
In 1989, as new affordable housing tracts brought new residents, Suisun City's "heart" - the downtown waterfront - began to decline. That year the city implemented an aggressive redevelopment program centered on the Old Town Waterfront and Historic Main Street Shopping District.
