Why do we need a second bridge?
Reasons for building a second bridge
A second crossing of the Ashburton River was deemed necessary to:
The Ashburton Transportation Study 2006
Investigation work carried out
In 2010 Council commenced technical investigation work into the possible location for a second bridge across the Ashburton River.
An Issues and Options report identified a number of issues regarding the existing bridge, including:
- The likelihood that projected future traffic volumes will exceed the bridge's capacity
- The majority of traffic on the existing bridge is local traffic travelling between Ashburton and Tinwald
- The lack of viable alternative routes should the bridge be closed due to natural events or accidents or other incidents on the bridge
- The vulnerability of the existing structure to natural events
A total of 13 possible bridge locations were considered. Each bridge option was considered against an extensive list of agreed criteria. Public feedback and consultation was undertaken via a public meeting, newsletters, open days and meetings with various stakeholders.
Further investigation work was commissioned in 2011 to re-look at a number of the options originally considered. A multi-criteria assessment was undertaken of each of these options, with each option being assessed against 16 set criteria. As part of this work a community reference group was established and a Social Impact Assessment was also undertaken.
Three options off Chalmers Avenue to the south of the Ashburton River best met the necessary criteria. Further public consultation was undertaken with open days, media and District Diary coverage and a feedback form was circulated to all residents. Of those options, Grove Street scored consistently lower than the east of Tinwald options, consequently Council resolved to focus on the two Chalmers Avenue to east of Tinwald options (an urban option and a rural option).
The Council held landowner only meetings as well as face to face meetings with all potentially affected landowners within the 'corridor' of the proposed routes. Council resolved on 4 July 2013 to a roading alignment proceeding to designation to protect the bridge location and associated road alignment. Further individual meetings were held with the directly affected landowners. Council then agreed at its 3 October 2013 meeting to proceed with the lodgement of the Notice of Requirement (NOR) for land designation .
Notice of Requirement and Land Designation
The designation is a form of "spot-zoning" of the proposed route in the district plan, which authorises the necessary work and reduces the requirement for additonal resource consents. The designation connects the southern end of Chalmers Avenue with a new bridge across the Ashburton River and onto a new two lane road through low density land east of Tinwald to connect with Grahams Road at the south end of Tinwald.
The Notice of Requirement (NOR) was prepared and the application for designation was lodged on 4 November 2013.
A public hearing of submissions was held from 10 March to 14 March 2014 in front of two independent commissioners, Andy Carr and John Milligan. Submitters who presented to the hearing included affected landowners, stakeholder groups and inviduals.
The commissioners recommendations to Council, which took into account the Notice of Requirement, planners' recommendations, the relevant national and regional planning documents and information presented at the hearing were considered at an extraordinary meeting on 22 May 2014.
At the meeting Council resolved to confirm the Notice of Requirement for the designation. The District Plan has been amended to reflect this decision.
