The New South Wales government will award a contract for the new airport gateway, a project valued north of $2 billion.
The successful private sector bidder chosen through the expression of interest process will construct the toll-free gateway project, with state government saying it aims to have contracts signed by mid-next year.
Plans aim to enable a faster route for travellers to the airport, which include bypassing 26 sets of traffic lights from Parramatta through to Sydney domestic airport.
The project also includes new connections from the airport’s domestic and international terminals to the Sydney motorway network at St Peters Interchange.
Transport minister Andrew Constance said the Sydney gateway plans aim to take 10,000 trucks and up to 100,000 vehicles a day off local streets in Mascot and improve connections towards Port Botany.
“There will be further time savings from Parramatta, Dee Why, Moorebank and Campbelltown, and provide relief to Southern Cross Drive, King Georges Road and the M5 East tunnel,” Constance said.
The estimated cost of the project is $2.2 to $2.4 billion for the road component of Sydney Gateway.
“The new gateway includes a dedicated flyover to the front door of the domestic airport terminal.”
The project will be delivered in two stages by NSW Roads and Maritime Services, this includes:
An alternative shared cycle and pedestrian pathway,
A four-lane road in each direction with two bridges over Alexandra Canal,
An airport freight access route
A four-lane raised road in each direction with bridges to cross Canal Road and the freight rail line
Widening of Qantas Drive, and
An elevated 'flyover' road to the Domestic terminals
Stage two is the Port Botany Rail Duplication, which is being delivered separately by the Australian Rail Track Corporation.
