Bridge and interchange building continue, and the Hi-Lab pavement construction is under way on the 22km Hamilton section which takes SH1 east of the city from Tamahere to Lake Road.
Earthworks are largely complete in the northern and central areas but continue in the south.
While the whole length is a busy construction zone, there is much activity in and around the Southern Interchange where the Hamilton section will connect to the completed Cambridge/Tamahere section.
Bridges are being built across the Mangaone and Mangaharakeke stream gullies, and two large culverts are required to take gully streams under a new local link road. Road crews have been working day and night on the new lanes running toward the city, which include the off-ramp to Hamilton.
We expect to switch traffic on to those lanes in early May which will allow construction of the expressway where it cuts through Cambridge Road. Read more about this work in the February project update.
The other four interchanges are also progressing. At the Northern Interchange, at Lake Road where the Ngaruawahia section joins the Hamilton section, the ramps are taking shape and pavement is under construction for more than 2km to Osborne Road.
The Resolution Interchange bridge abutments are in the final construction phase, and there’s been good progress on extending Resolution Drive from the city out to the interchange.
The remaining two full diamond interchanges at Greenhill and Ruakura are also now bridged and work continues on ramps and connections.
Horsham Downs Road remains closed to build a bridge over the expressway. Traffic is expected to be crossing the new bridge by the end of the year. Another bridge is taking shape where the expressway crosses Puketaha Road. This has been spanned and decked.
The 150-metre Mangaonua Stream bridge is the longest of the 17 bridges on the Hamilton section. Construction of bridge pile caps and centre columns continues into autumn.
The annual project open day will be held in spring this year when we hope to offer bus tours along the expressway route.
