Sturges Road $8.6m Replacement Bridge Work Starts – Photos (Part I)
A start has been made on the $8.6 million Henderson’s Sturges Road replacement bridge project, taking place next to the train station there.
Managed by Waitakere City Council, the year-long project will be done in stages over the next 12 months, being completed in December.
Unlike the Remuera St Marks bridge, the council has to contribute to the cost of this, as I reported earlier.
The old 1940 bridge built by the government’s Railways department so steam trains could cope with the gradient, has reached the end of its life and is cracked and so had to be demolished.
While the new bridge is built, a single lane Bailey bridge, controlled by lights, is being installed. Pedestrians and cyclists will share that temporary footbridge.
Construction work on the new bridge proper won’t begin until late March.
The new bridge will be built one side at a time.
Once complete, the new Sturges Road Bridge will feature three traffic lanes and shared pedestrian and cycle paths on both sides.
The old bridge was not suitable for the electric trains. Improvements were needed to provide 60cm more clearance for electrification and for the double track underneath.
So the new bridge deck will be around 60 centimetres higher than the former structure, requiring the road level on the approaches to the bridge to be raised and widened.
At the moment, workers are doing retaining works from the track level to the base of the bridge abutment.
On average, 17,000 vehicles used the old bridge each day.
The work has meant a road closure in Sturges Rd between Swanson Rd and Septimus Place until January 18, when the rail corridor opens again.
