The Seatoun Tunnel will have its pedestrian handrail extended and receive new LED lighting alongside earthquake strengthening work in early 2019.
The work is part of an ongoing programme by the Wellington City Council to improve the safety and accessibility of Wellington’s earthquake prone structures.
Alongside the essential strengthening work, plans include extending the existing pedestrian handrail on both sides of the tunnel, and replacing the sodium lights with new more efficient LED fixtures.
The 112-year-old tunnel is a Heritage structure so it will be a priority to ensure it maintains its current charm, however the inside will be painted to make it brighter and safer for residents to walk to through.
The strengthening work will require new buttress overlay beams to be built in front of the existing ones of both sides of the tunnel, ground beams to be constructed behind the parapets of both portal walls, ten rock anchors installed on each side of the tunnel, and a new ground beam constructed in front of the retaining wall, held in place with four rock anchors. The defective areas of the portal will be removed, and both walls will be painted.
Vehicle and pedestrian access to the tunnel will be affected at times while the work is underway, and diversions will be in place.
More information will be available nearer the time.
