SR 282 was initially designated in 1967 solely along Fourth Street from SR 75 to the Naval Air Station; however, it was not to be in effect until the San Diego–Coronado Bridge was completed. Nevertheless, before the bridge opened, the designation was added in the 1968 legislative session, along with the portion of Orange Avenue from the Coronado Ferry landing to Fourth Street, which was to be removed once the Coronado Bay Bridge opened. The designation came into effect on February 21, 1969. In April, plans were under way to repave Fourth and Third Streets and add signals at the Orange Avenue intersections. The bridge opened on August 3, 1969. In September, the City of Coronado added Third Street as a truck route going westbound to the base, in addition to the already-existing Fourth Street truck route leaving the base.
