A map of sites where you may experience delays on Southland state highways due to maintenance or third-party contractor work can be found here, and these sites are listed below. Please note that weather forecasts over the next few days are predicting overnight frosts – please check conditions before you leave - https://www.journeys.nzta.govt.nz/journey-planner.
Highways South work with temporary speed limits this week:
Third party work and events with traffic management in place this week:
Note: Two key sites beginning in the next fortnight:
SH1 Bluff Highway, traffic lights and speed limit from 11th August 11 for about two weeks drainage work
This site is programmed for a renewal this construction season. The first stage is the drainage and flanking of the highway shoulders of a 3km stretch from just south of Avon Road to just south of Blythe Street. The 3km stretch will be split into sections of around 500m at a time, to reduce the impact and delays to traffic. We anticipate delay times of approximately 5 minutes at the site.
SH94 at The Key, traffic lights and speed limit from approx. 18th August until mid-November for drainage and renewal work. We anticipate delay times of approximately 5-10 minutes at the site.
