Auckland Business Forum chairman Michael Barnett said some of the projects had sat on Auckland plans for decades, while Road Transport Forum chief executive Ken Shirley said the interest-free loan showed a heartening commitment to long-term infrastructure investments vital for sustained economic growth.
"Some of our Auckland operators, especially those moving freight to and from the Ports of Auckland, will be disappointed that money has only been allocated for further investigation of preferred scope of the east-west route, but it is essential it has robust scrutiny," Mr Shirley said.
Manurewa-Papakura councillor Calum Penrose said investing $210 million towards the upgrade of the Takanini interchange and widening the Southern Motorway between Manukau and and Papakura was welcome news.
"The start date for work on the Takanini interchange is 2016-2017 which can't come soon enough."
Generation Zero spokesman Dr Sudhvir Singh said: "The City Rail Link has been identified by the people of Auckland as the top priority for transport in Auckland, yet the Government has missed the opportunity to fund this essential piece of infrastructure in favour of largely unnecessary roading projects."
The motorway projects in the Budget include an immediate start on three Northern Motorway improvements, five projects on the Southern Motorway around Takanini and scoping the east-west link through the industrial southeast.
Mr Brownlee said the projects would capitalise on work under way, such as the western ring route.
