Funding of the AHB walk/cycle way 

The most likely funding source for the Auckland Harbour Bridge walk/cycle way is from an existing fuel tax known as "R" funding.  It's 5c included in the price of every litre of fuel sold in the Auckland region from 2005 to 2015.

This "R" funding is expected to generate a total of $770 million, of which 7% is to be allocated to regionally important Travel Demand Projects (such as the Auckland Harbour Bridge walk/cycle way) - this equate to $54 million

ARTA has include the AHB walk/cycle way in its list of potential projects to be funded with "R funding" see this January 22, 2008, letter from ARTA's CEO to the ARC regarding funding, on page 3 the Auckland Harbour Bridge walk/cycle way has been ear-marked $60 million  ("100% FAR" means 100% Financial Assistance Rate, that is: no local council contribution is required).

So whilst the potential funding is in place, the cost of the walk/cycle way needs to win general public and political support to proceed.
