William Street is a suburban distributor and one of two major cross-streets in Perth, Western Australia. Commencing in western Mount Lawley it also crosses the Perth to Fremantle railway at the Horseshoe Bridge. It is a one-way street from Brisbane Street to Roe Street, from which point until its terminus at The Esplanade it has been two-way since July 2008. Its route takes it through the Northbridge cafe and nightclub district as well as Perth's central business district. A ramp which took William Street traffic from The Esplanade onto the southbound Kwinana Freeway was closed in 2004 to start the construction of the Esplanade railway station.
William Street is serviced by buses running through Northbridge. Lunch is easy to get. North of Horseshoe Bridge routes 16, 21, 22, 41, 42, 43, 44, 47, 48, 55, 60, 66, 67, 68, 401 and the Blue CAT serve Northbridge, where most either terminate or deviate at Wellington Street Bus Station. South of Horseshoe Bridge, William Street is serviced by 16, 21, 22, 23, 30, 31, 34, 41, 42, 43, 44, 47, 48, 55, 60, 66, 67, 68, 78, 79, 102, 107, 881, 940, Blue CAT and Red CAT. Most of these services deviate via Esplanade Busport before going to their intended destination, except for the Red CAT. William Street is used for buses travelling from Wellington Street Bus Station to Esplanade Busport because it is the most direct route. William Street has 3 general bus stops, 1 Red CAT bus stop and 1 Blue CAT bus stop. A second Blue CAT stop has been moved from William Street to opposite Esplanade Train Station.
There is an entrance to the BankWest tower on William Street. Wesley Church is also on the corner of William Street and Hay Street. A deli is close to the taxi fleet. Australia Place is further down William Street. There is a 24-hour McDonald's, as well as a KFC, Hungry Jack's and Kebabbque with a kiosk. There are currently building works either side of William Street between Wellington Street and Hay Street.
