Higgins are the exclusive Pavement and Surfacing subcontractor for Fletcher Construction.
This $105M section of the Waikato Expressway for NZTA comprises a 4.8km re-alignment of SH1, 2 interchanges and alterations to local roads.
Higgins contributed technical expertise through the initial stages of design and costing in the ECI (Early Contractor Involvement) process. This culminated in the award of a contract for construction in January 2013. The design places the new 4 lane expressway to the west of the existing State Highway 1, and improves safety at the Te Kauwhata and Rangiriri intersections.
Since last year, traffic has been running on two temporary alignments to allow the new Te Kauwhata and Rangiriri Interchanges to be constructed. As at August last year the first of five 7m high Mechanically Stabilised Earth (MSE) retaining walls were completed at the Te Kauwhata interchange.These 7m high walls support the road on the bridge approaches and feature a decorative concrete facing reinforced with layers of polyester grid for strength and earthquake resistance. Work is also continuing on a similar wall adjacent to the Glenn Murray Bridge at Rangiriri.
About 200,000 native plants will be used for re-vegetation, around 30,000 have been planted this year with the remainder to be planted in 2016.
The new roundabout at Te Kauwhata Road/Wayside Road is almost finished with just a few additional works to complete. The preparation of the final alignment south of Rangiriri is underway. The project is due to open late 2016 to early 2017.
