The Southern Outlet opened to traffic in 1968. In the absence of a Kingston Bypass, the Southern Outlet's southern Terminus was the Kingston Interchange. In 1983, a bypass corridor for the future Channel Highway was proclaimed west of the existing Alignment. In 1986 Algona Road was opened as a 2 lane road. Algona Road was constructed for a task such as connecting Kingston Bypass to Blackmans Bay and has available space dedicated for a second carriageway. The proclaimed bypass corridor runs from the Algona Road/Channel Highway Junction to the Kingston Interchange.
