The Department of Planning, Transport and Infrastructure (DPTI) advises that night and October long weekend tunnel works will be undertaken at the intersection of Hackney Road and Botanic Road from Sunday 11 September 2016.

Works to complete tunnel wall sections, installation of the roof and road resurfacing will occur on the following dates and times:

From Sunday 11 September 2016 to Thursday 29 September 2016 – each night from 7pm to 6am. There will be no night works on Friday 16, Friday 23 or Thursday 29 September, 2016.

From 10pm Friday 30 September 2016 to 6am Tuesday 4 October 2016 – works will be undertaken continuously through the Long Weekend.

From Tuesday 4 October 2016 to mid-October 2016 – each night from 7pm to 6am  for approximately one week (except Fridays) until complete.

During these works the intersection will be closed to all through traffic travelling along Botanic Road and North Terrace. All through traffic will be detoured via East Terrace and Rundle Road, including emergency vehicles and buses. The left turns from Botanic Road into Hackney Road and from North Terrace into Dequetteville Terrace will remain open. The right turn ban at the intersection remains in place.

Night works will also take place from mid-October 2016 to mid-November 2016 (except Fridays) between 7pm and 6am along the western side of Dequetteville Terrace. These works will not impact traffic travelling through the Hackney Road and Botanic Road intersection, however lane and speed restrictions will be in place.

This is the last phase of planned night works at the Hackney Road and Botanic Road intersection, with  all future tunnel works in this location taking place underground.

Motorists and road users are requested to take extra care when workers are on site and observe traffic signage and speed and lane restrictions when travelling through the area.

Every effort will be made to complete works to schedule however all works are subject to weather conditions.
