Beams waiting to be lifted into place

SH25A Taparahi - decking the way

The first stage of the bridge deck construction has started. The team installed 3 spans of the girders last week and over the weekend. The girders are the long steel beams that span between the abutments and piers, and support the bridge deck.

The girders are spliced together in combinations of 18m and 29m sections and then lifted into place. There is also steel bracing between the steel girders which is progressively installed as the team work their way across from abutment A (the western abutment) to abutment D (the eastern abutment)

This week the team is focused on preparing the girders for the final span of Pier C to Abutment D. The lifts are very dependent on the weather. If the wind is too strong it is not safe to lift the girders into place.

See below some more activities undertaken last week on and off site:

Abutment A: The wingwalls were finalised and are ready to be poured this week.

Abutment D: The wingwall steel reinforcement has been tied and are now ready for the concrete pour this week.

Pier B and C: Plinths were poured and the third span was lifted in place over the weekend.

Offsite: The final 3 steel girders are due to be despatched from Napier and arrive on site this week. In the meantime, fabrication continues on the 138 concrete pre-cast panels (which will be placed on the steel beams to form the bridge deck) and 52 pre-cast side barriers.

Look after our road workers

Waka Kotahi is committed to a safer Aotearoa New Zealand where no one is killed or seriously injured on our roads. This includes keeping our road workers safe - the people working on the country's roads who are doing their best to make them safer for you.

There's no excuse for abusing people as they go about their job.

Be kind, be respectful, and be careful around road workers. Just like you, they deserve to get home at the end of the day.

Watch: Look after road workers, they're part of your community.
