So far, 5.3km of the 18.4km stretch of Portobello and Harington Point Rds from Marne St to Harington Point has been widened and a shared path added.
The remaining 13.1km is planned to be done over the next 12 years at a cost of $27 million, subject to funding - the New Zealand Transport Agency is expected to subsidise the work by up to 65%.
The capital work is built into the council's long-term budgets, although staff have indicated several sections can now be done within existing budgets.
Under the present agreement, determined in consultation with the community in 2005-6 and which focuses on making the improvements in the built-up areas first and then linking them, sections of Harington Point Rd are programmed to be done this year and next.
The remaining sections linking the greater metropolitan area to Macandrew Bay are not programmed to be completed for another six years.
However, council staff say feedback from locals and other interested parties over the past year has indicated a desire to complete the Dunedin to Macandrew Bay section earlier.
Transportation staff have requested direction from councillors, who will discuss the matter during their 2014-15 annual plan discussions this week, on whether to change the sequence of work.
Noting it would be practical to do the sections of Harington Point Rd scheduled to be improved in 2014 and 2015 because of the poor condition of the existing sea wall and road, projects engineer Evan Matheson outlined three options for councillors to consider: do the critical widening of Harington Point Rd then work at Broad Bay and Portobello, but leave the less populated sections in those areas until the end of the programme, meaning the Dunedin-Macandrew Bay sections would be completed a year earlier; complete the critical work at Harington Point Rd then start from the Dunedin end and work north, completing the Dunedin-Macandrew Bay section three years earlier; or simply start from Dunedin end and move north, completing the Dunedin-Macandrew Bay section four years earlier.
