 The busway was officially opened in February 2008 after several years of construction, though the Albany and Constellation stations had been operating since December 2005 using the normal Northern Motorway lanes.It was credited with reducing peak traffic on the Northern Motorway by around 500 cars each rush hour one month after opening, and about 39% of passengers on the Northern Express bus service had never used public transport before.The busway was initially used by 70 buses per hour during peak time.
