Connections August 1994

The Hamilton Regional Office published a newsletter called Connections, this is the first edition. It summarises progress on a range of projects in the Waikato region. Of historical note are:

• Upgrades to SH25 around the Coromandel Peninsula including completing the sealing of the highway!
• Three major SH1 projects that all comprised part of the Waikato Expressway and were the first stages of the expressway.

Other projects listed include realignments at Mangaiti Hill south of Tokoroa, Tuahu realignment south of Atiamuri (both on SH1), Chinaman's Hill realignment and Te Kawa Crossroads on SH3, and the Whakahora Deviation on SH27.  Altogether it highlights how many relatively small, but high value projects were being advanced with Benefit Cost Ratios of 5 and above in the region, primarily because they would reduce serious accidents.

SH25

In 1994, there was concern about the need to make the only highway around the Coromandel Peninsula safer and more resilient. A key part of this is sealing the section from Whitianga to Coromandel to enable a sustainable and attractive tourist route.  

SH1

The term "Waikato Expressway" had not been coined yet, but Transit NZ had already made a strategic decision to plan for a four-lane highway between Auckland and Cambridge.  The three projects mentioned are under construction, out to tender and under design respectively:

• Tamahere Deviation: 3.5km of expressway south of Hamilton at the intersection with Airport Road, justified due to the poor accident record, but showed some considerable foresight to build the first segment of expressway in Waikato.  Note the construction cost of only $9 million.
• Mangatawhiri Bridge Realignment: This segment south of Pokeno eliminated a sharp and narrow section of highway (now Pioneer Rd).  Noting that it took 2.5 years of loading on the ground due to the soft soils, which would prove to be an issue for other segments of road in this area, and was a short four-lane segment designed to connect with..
• Pokeno Bypass: Hard to believe now, but in 1994 SH1 went through Pokeno.  The new 4km bypass connecting directly with the (then) recently opened Bombay Hills Interchange would, with the Mangatawhiri project, effectively extend the expressway south to Mercer,  As with other early segments, the accident rate in Pokeno, plus travel time and fuel savings made this a highly efficient project to advance.
