The Gateway Motorway (M2 to Eight Mile Plains and M1 to Pine River) is a major tolled motorway in Brisbane, Queensland, Australia which includes the Sir Leo Hielscher Bridges (former Gateway Bridge). The motorway is operated by toll road operator Transurban.
It bypasses Brisbane in order to provide easier access between the Gold Coast and the Sunshine Coast. It runs from the M2 Logan Motorway in Drewvale (near Browns Plains) to the Gympie Arterial Road in Bald Hills. At the interchange with the Pacific Motorway at Eight Mile Plains (Pacific Motorway exit 16), its original terminus pre-1997, the route number changes from M2 (Logan Motorway - Pacific Motorway) to M1 (Pacific Motorway - Bruce Highway (Gympie Arterial Road)). The Sir Leo Hielscher Bridges are part of the Gateway Motorway and the Motorway provides access to the Port of Brisbane, Brisbane Airport and Brisbane Entertainment Centre.
The motorway was constructed to connect the then-recently opened Gateway Bridge to the Bruce Highway in the north and the Pacific Motorway in the south. Construction on the road commenced in March 1985 and it was opened to traffic in four stages between August and December 1986.
Originally, the route was called the Gateway Arterial Road because the road was not at motorway status, the road passing through three large roundabouts north of the Brisbane River. Therefore, to cope with the heavy traffic, the government began upgrading the road in 1987. Duplication to four lanes and grade-separation was completed in several stages between 1989 and 1996.
In 1995, construction began on a southern extension to the Logan Motorway, creating the Southern Brisbane Bypass. The road was opened to traffic by Vaughan Johnson, then-Minister for Transport and Main Roads, on 13 May 1997. Following this work, the road was renamed Gateway Motorway.
In 2007, construction began on the Gateway Upgrade Project, which duplicated the Gateway Bridge, added a deviation between Eagle Farm and Nudgee and upgraded the motorway south of the river. The duplicate Gateway Bridge was opened on 24 May 2010 and both bridges were renamed the Sir Leo Hielscher Bridges. The original bridge was refurbished to match the new structure and was finished on 28 November 2010. The northern deviation was routed east from its old alignment (the old alignment is now named Southern Cross Way) and added a second access road, Moreton Drive, to Brisbane Airport. The deviation opened on 19 July 2009 whilst Moreton Drive opened on 3 December 2009. South of the bridges, the motorway was expanded to 9 lanes up to the Wynnum Road interchange, and 8 lanes to the Old Cleveland Road interchange. From that point the motorway is six lanes up to the Pacific Motorway Merge. The upgrades between Lytton Road and Mount Gravatt-Capalaba Road were completed on 28 January 2010, while the final stage between Mount Gravatt-Capalaba Road and Pacific Motorway (also the final stage of the entire Gateway Motorway Upgrade) was opened to traffic on 30 July 2011.
Upon its original opening, the road did not have a route number. However it gained the Metroad 1 shield in March 1994, before being replaced with M1 in 2005. Manual toll booths were removed and replaced with electronic toll gates (which require vehicles to have a transponder attached to the windscreen) in 2010.

Southern Cross Way
Southern Cross Way is a 7 kilometres (4.3 mi), 4 lane motorway which branches from the Gateway Motorway at Eagle Farm before merging back with it at Nudgee. Prior to 2010, Southern Cross Way formed part of the Gateway Motorway before the Gateway Upgrade Project constructed a shorter route (and additional Brisbane Airport access road, Moreton Drive), between those two suburbs. The old, longer motorway section was preserved, connected to the deviation and renamed Southern Cross Way, after the aircraft flown by aviator Charles Kingford Smith, to allow motorists to distinguish between the routes. Southern Cross Way (also colloquially called the 'Old Gateway Motorway') thus follows the previous alignment of the Gateway Motorway between Eagle Farm and Nudgee and has three exits.
The entire motorway is in the City of Brisbane local government area.
