The Matakohe bridges replacement and SH12 deviation make a major advance this week with the arrival on site of the ‘super tee beams’ for the smaller of the two new bridges, Bridge No 1 over the Parerau Stream.
The 50-tonne reinforced concrete beams are programmed to be transported from Auckland to Matakohe from Wednesday through to Saturday and contractors Fulton Hogan warn of delays to traffic with the beans and transport units measuring more than 30 metres.
“Please expect a slower journey should you find yourself driving behind one of our transporters hauling an over-dimensional load,” a company spokesman warns.
“There may be occasions when the transporter comes to a stop and the rear, independent unit is manoeuvred to negotiate the 50-tonne beam around a tight corner. There are limited opportunities on SH12 between the SH1 turnoff at the Brynderwyns and Matakohe to safely pass even shorter vehicles.
Each beam plus its transporter measures more than 30 metres and pilot vehicles will accompany each transporter and help manage traffic flows. The transporters shorten in length for their return journeys to Auckland.
Each transporter hauls one beam at a time. Transporting will start on Wednesday, September 12 at night
