Auckland's successful Northern Busway has been set back by a Government decision to exclude an extension to Albany from an $815 million package of accelerated roading projects.
A Treasury paper shows the Government considered a Transport Agency plan to extend the dedicated bus highway from Constellation Drive, but backed off after being told it would cost an extra $250 million.
But it is pressing ahead with northern corridor roading improvements costing $460 million, including a full motorway-to-motorway "elbow" link extending four kilometres from State Highway 18 to Greville Rd on SH1 - parallel to the first part of the busway extension route of similar length.
Also included in May's Budget was $210 million for Southern Motorway projects from Manurewa to Papakura and $140 million for State Highway 20A to the airport from the city.
Labour's transport spokesman Phil Twyford says it reflects "the entrenched motorways bias that this Government has."
