Councillors heard Route K would not turn the funding corner until about 2021-22 when usage of the road was predicted to reach the point where revenue began repaying all the loan costs. In the meantime the interest on the loan would continue to be rolled into the capital.
Councillor Bill Faulkner called for a meeting to be set up with the city's MPs as quickly as possible. "We need to keep up the political conversation."
Cr Faulkner said the economic downturn and the Christchurch earthquake meant the country was in a different space to when the council began the debate about the agency taking over the debt.
He said the council needed to salvage the best deal it could in the meantime because the agency was constrained by both the law and the amount of money it had to spend.
Councillor Murray Guy opposed the basis of a settlement with the agency, saying he was totally opposed to tolling.
He complained they would be giving the agency a fit-for-purpose road for a state highway while the agency was wanting to hand back to the council the 15th Ave-Turret Rd corridor which needed to be widened to four lanes. He had little confidence a political solution would be found.
Councillor Bill Grainger said the council had to be more forceful in its discussions with the city's MPs.
Councillor Rick Curach feared the council would lose its bargaining power and leverage by agreeing to allow Route K to become a state highway.
The proposed deal with the agency was passed 6-4.
