Queenstown Lakes Mayor Vanessa van Uden has sought an assurance from the Otago Regional Council regional transport committee about when a planned Kawarau Falls replacement bridge will proceed.
She asked the Otago Regional Council's transport committee to prioritise the project as part of a land transport programme which is being developed to seek subsidised funding from the New Zealand Transport Agency.
Otago's six council authorities have promoted about 203 proposed transport projects for funding consideration.
However, the transport committee could not include the planned Kawarau Falls bridge on any ranked table of local projects, because the crossing was part of a state highway and administered by the NZTA, he said.
Regardless, the regional transport committee ranked the Queenstown bridge project behind a more desirable option to replace the structurally compromised 123-year-old bridge across the Clutha River at Beaumont.
There were no structural issues with the single-lane SH6 bridge at Kawarau Falls, Mr Woodhead said.
NZTA Otago-Southland acting state highways manager Ian Duncan said both bridge projects were tentatively programmed for construction starts in 2017-18.
"The Beaumont would be prioritised ahead of Kawarau Falls Bridge, as it is considered essential infrastructure, due to serviceability limits on that bridge," he said.
The bridge was nearing the end of its serviceable life.
Work carried out on the structure in the past two years, such as the installation of traffic signals to reduce vehicle speeds over the bridge and combined with "ongoing maintenance" would extend its serviceable life for about five years, Mr Duncan said.
"The bridge is frequently monitored and inspected to ensure it is up to the required safety standard," he said.
The main drivers for replacing the Kawarau Falls Bridge were its traffic capacity and travel time savings, given some "localised" congestion issues on the bridge for relatively short periods during busy times, such as in school holidays and the ski season.
"With respect to the Kawarau Falls Bridge, its remaining serviceable life as a single lane structure is well beyond the 10-year programming horizon."
Certain factors could affect the planned construction start dates, he said.
The programming for Beaumont was based on anticipated serviceable life, while the Kawarau Falls Bridge was based on priority and anticipated programme cash flow.
"Changes in either priority and or programme cash flow may affect timing [for the Kawarau Falls Bridge]," Mr Duncan said.
Ms van Uden could not be contacted for comment yesterday.
