Possible Delays at SH1 Junction

Possible Delays at SH1 Junction

There will be an early morning  concrete pour happening on Tuesday 21st January at our Pūhoi bridge site (Pier B) for the headstock structure. This is near our SAP 9 entrance, just north of Pūhoi Road.  The pour will start at 4am and last approximately seven hours,  staff will be on site earlier than this to set up.  Works will be modified to comply with night noise limits.


With the summer season in full swing we are making the most of the fine weather and moving as much dirt as we can, there’s  a lot of work happening at the moment in the South.  From the work happening near the Johnstones hill tunnels, Billings Road to Pūhoi and all the way to Mahurangi West Road.  We are moving and smoothing the earth as fast as we can getting it ready for pavements (roading surface) to be put down. 


On top of that we have our structures team working hard on the bridges in Okahu and Pūhoi, you can really see the progress now which is quite exciting.  The team have started lifting the large beams/girders onto the Okahu bridge, they still have a few more lifts to go before they start on the deck/roading surface on top.

There are two more Headstocks to pour at the Pūhoi site with the one (as above on the 21st Jan) being the first one, the will pour the last headstock approximately a week later.  I will notify you closer to the time this happens. 


Lifting of the girders onto the Pūhoi bridge is also happening soon, and one of the first girders to be lifted on top will span over the top of Pūhoi road.  There are four 44meter beams to lift into place over Pūhoi Road, so as you can imagine this will take some time and careful planning to complete.  The lifts are also very weather dependant as there can’t be too much wind when the lifting happens. There is also lots of other work that needs to happen like bracing the girders, and a bit later on placing the deck panels and concreting the deck on top. 


For safety reasons, the placing /lifting of the girders will require a temporary closure of Pūhoi Road (between SH1 and Pūhoi Close) for a few hours at a time (detours will be in place).  This will happen at night between the hours of 9.30pm and 4.30am and is due to start around mid February.  The Pūhoi Road/SH1 intersection will be busy over the next couple of months so please slow down when coming around this corner. There will be Stop/Go traffic management in place for a while, predominately at night time, to allow us to work on the bridge safely.  There will be no works on Friday or Saturday nights. 


Dates have not been confirmed yet so this is just a heads up that its in the pipe line, I will send out an official notification closer to when it happens and talk more to those that this may affect.  If you are active or know of others that travel at this time (9.30pm and 4.30am)  I’d love to know ahead of time so I can keep those that need to know regularly updated.  Provisions have been made so emergency services are still able to get though during road closure times. 


If you have any concerns, please don’t hesitate to contact us.


Kind regards
