Significant and necessary roadworks on part of State Highway 99 in Southland will mean 24/7 closures over about two weeks, followed by lesser traffic restrictions, which road users are encouraged to plan for.
The 1.3km section of SH99/Wallacetown-Lorneville Road, between the intersections of Ryal Bush-Wallacetown Road and Underwood-Linds Bridge Road, is scheduled to be closed for culvert strengthening to provide flood protection, from 6.30am on Monday 23 February through to Monday 9 March (see map below).
During this time, a detour will be available for all vehicles via Ryal Bush-Wallacetown Road, Collinson Road and State Highway 6/Winton-Lorneville Highway. All businesses will be able to remain open and accessible, while residents will continue to have access to their properties during this closure.
The nature of the work means that partial closures will not be practical during this time. Drainage and road stabilising work will also be carried out alongside the culvert strengthening to make the most of the closure.
From Monday 9 March through until early April, the full closure will be lifted, but the site will operate daily from 7am to 6pm with only one lane of traffic, temporary traffic lights, and a 30km/h temporary speed limit. This is to enable road renewal work which includes excavation, fill and resurfacing.
Because of the volume of traffic, people should expect delays of up to 20 minutes. Access for businesses and residents will be maintained during this second stage of work and lane closure.
The annual average daily traffic at a count site on SH99 close to the closure area was 5673 as of a year ago.
These two periods of work are dependent on various factors such as weather and could be postponed or rescheduled at short notice. Stay up to date at our Journey Planner site.
