Cyclists and walkers are closer to being allowed to use the Auckland Harbour Bridge after traffic chiefs conceded the crossing could be strengthened to carry a secure path under one of the clip-ons.
Beefing up the bridge's citybound clip-on to support a pathway would make the cost of a no-frills structure and access ramps $23 million. The previous estimate was $17.3 million.
A pathway working group - which includes the Getacross Campaign, a cycling and walking lobby - acknowledged cyclists and walkers would have to be restricted to ensure numbers on the bridge did not exceed allowable loadings.
But it is confident its basic proposal could be paid for by users through tolls - over 20 years instead of the 15 years suggested earlier - after which the pathway could be transferred to public ownership.
It proposes a $2 toll for holders of Auckland Transport's Hop cards, and $5 for casual users, to capture what it believes will be a strong tourismmarket.
