Portsbridge Creek, known officially as Portsea Creek,[1] formerly as Portsea Lake and informally as Ports Creek, Port Creek, Portcreek and Canal Creek, is a tidal waterway just off the southern coast of England that runs between Portsea Island and the mainland [2] from Langstone Harbour to Tipner Lake.
The unofficial Portsbridge Creek name for the creek is an outdated name, formerly used when Portsea Island used to have only a single road bridge (named the Portsbridge) crossing between Portsea Island and the mainland. In modern times, Portsea Creek now has other crossings via road, rail and pedestrian bridges.
Through its history, Portsea Creek has been made navigable a number of times and it is today navigable for small boats, depending on tide.
