Work is under way on the Aotea Quay overbridge bridge barriers
The beams and columns supporting the 1936 bridge were replaced in stages over the past four years as part of a $1.85 million programme designed to maintain the structure and make it safer.
The next and final phase of work will involve replacing more than 80 concrete bridge barrier panels with new ones, and repairing others. Rockfall netting will also be installed on the bank adjacent to the northern exit lane where there have been slips in the past.
Work is due to start on Monday 15 June and should be complete by early October. It will be carried out in sections – on the northbound lane first and then the southbound. The speed limit will be 30km/h.
The bridge is above the railway lines so, for safety reasons, some of the work will have to happen at night when there are no trains running below. The night work will also help minimise the impact on daytime traffic flows.
Cr Andy Foster, who chairs the Council’s Transport and Urban Development Committee, says the project is part of an ongoing programme to protect key routes by strengthening tunnels, road and pedestrian bridges and building new retaining walls that are designed to perform well in earthquakes.
“The work that has already been done on this bridge and this last stage of improvements are designed to extend its life by another 50 years.”
The work will be carried out by Brian Perry Civil. Daytime work hours are Monday to Friday, 9am to 4pm. Night work will happen Sunday to Friday between 9pm and 5am.
