In Transit - June 1997 - No. 81 - Annual safety certification of highways, Newlands Interchange and other projects

 The June 1997 issue of In Transit had articles on the following points:

• An annual safety certification of the state highway network is to be produced to identify opportunities to improve the safety of the network. This covers factors like roadside shoulder slopes, road camber, obstructions on the road edge, running a checklist over the entire network, with annual reviews of this status.
• Retirement of John Kearney from the Transit NZ Board. He commented that establishment of Transit NZ improved control and management of the state highway system, as it looked at it from a system not a sectoral point of view. 
• Work commencing on the $16.5m Newlands Interchange project in Wellington on SH1.
• Near completion of a new level crossing at Rolleston with Selwyn District, adjacent to SH1 (a site of four fatalities).
• Vibralines to be installed on the edges of Auckland motorways following successful trials on the Johnsonville-Porirua Motorway near Tawa. This is expected to reduce the 400 accidents a year due to vehicles running off the motorway network, by cutting injury crashes by 15%.
• Transit NZ purchased land as part of a property development north of Tauranga to enable a corridor for the future northern Tauranga arterial project (what is now known as Takitimu North Link).
• Options being investigated for the Te Puke Bypass (what is now the Tauranga Eastern Link) SH2.
• Work to start on the $7m Kaitoke realignment on SH2 Wellington between Upper Hutt and the Remutakas.
• Joint planning study launched with Kapiti Coast District Council for what was to be called the Kapiti Western Link Road project (a local road to connect Raumati, Paraparaumu and Waikanae to relieve SH1). This project was cancelled in favour of the Kapiti Expressway which was started in 2013 and completed in 2017, bypassing Paraparaumu and Waikanae with SH1.

In Transit - April 1997 - No. 79 - Focus on fixing crash black spots

 

In April 1997, the Transit NZ newsletter (no longer monthly as the previous edition was February, focused on the success in reducing the road toll.  It also reported on opening of a motorway extension in Auckland (SH20 Mangere to Papatoetoe) and commencement of work on another (SH1 Albany to Puhoi enabling works), with cost estimates that look remarkably cheap compared to today in real terms.

1996 had the lowest road toll in 32 years at 515 fatalities, 67 fewer than in 1995, and only higher than 1964 which had 428 with a much lower population and VKT.

It was attributed to a focus on drunk driving and speeding, along with the long standing "black spot" programme established in 1985 focusing on locations where there had been at least three injury accidents within five years. On all roads there were 4200 fewer injury crashes at locations remedied comparing 1985 to 1996, reducing crashes by 28%, with about half of the reduction on state highways.  The crash investigation programme gathered data on each site to identify the causes of crashes and what infrastructure improvements might address them.  A wider initiative was a highway inspection process to identify network deficiencies and develop a safety culture to address possible issues, like overgrown foliage blocking visibility at intersections. Covert speed camera trials were being considered to address speeding.

Page 2 continued the article on safety, but also South American interest in the reforms in the road sector, particularly from Colombia, with some observations on technology such as telecommuting and enabling motorists to "dial up" traffic cameras as part of Auckland's Advanced Traffic Management System (ATMS) (a precursor to accessing them online).

Page 3 announced enabling contracts had been let for the then $165m Albany to Puhoi extension to the Northern Motorway.  At the time, the motorway was to be four-lanes to Orewa, and only two-lanes with passing lanes from Orewa to Puhoi, but built to a standard to enable four-laning at a later stage (the tunnel was not envisaged at this time).  The project was intended to be completed by 1999, but only the Albany to Silverdale section had been completed by that date.  At the time, the project (ALPURT as it was then called) was the largest single road project ever undertaken in New Zealand, primarily because all other sections of motorway in Auckland (and other cities) were built piecemeal over many years.  

Page 3 also saw the opening of the SH20 extension between Mangere Bridge and Papatoetoe, and the Airport Motorway as far as Kirkbride Road intersection with George Bolt Memorial Drive (then only a single-lane highway with passing lanes). The entire project was a five km extension built at a cost of $40m.  It was notable as the first ever design-build contract let by Transit NZ. The project notably included four pedestrian over bridges along with eight local road over bridges, and associated cycleways. It was reported as having significantly reduced congestion on urban roads through Mangere, effectively combining two sections of motorway from Hillsborough Road through to Roscommon Road.  It also significantly reduced travel times to and from the airport (noting there was no eastern access route to the airport at the time).

Page 4 reports on the use of a vehicle using lasers to measure road surfaces on all state highways to help collect data for the RAMM asset maintenance system to better plan road maintenance across the network.  Finally, there is a report on the realignment of SH6 Rai Valley in Marlborough ($263,000) which required relocation of a 50 year old kauri tree. 

In Transit - February 1997 - No. 78 - Focus on repairs after Cyclones Fergus and Drena

 

In NZ, emergency works were always not too far away as part of the portfolio of works for road networks.  In February 1997, Cyclones Fergus and Drena caused extensive damage mainly in the Coromandel District.  The feature article highlights the cost of $5.8m (1997 prices) to fix the damage on SH25 and SH2, but also damage on SH1 (Brynderwyns), SH35 and SH88.

Other stories include:

• Review of Special Purpose Roads: Special Purpose Roads were a category of local road that were subject to higher Financial Assistance Rate funding (typically 75%) from the National Roading Programme compared to other local roads (which obtain typically 50%). Such roads get higher funding because of a high proportion of tourist traffic, be below state highway standard and pass by properties with rating potential much lower than the costs of maintaining the road.  Curiously, this decision has mostly funding implications, yet was being carried out by Transit New Zealand which was no longer the funding agency, as Transfund New Zealand had been formed the previous year. 
• Declaration of the revoked section of SH38 as a Special Purpose Road: As part of the State Highway Review in 1995, Transit New Zealand revoked SH38 between Te Whaiti and Ruatahuna. Transit announced it had decided to classify it as a Special Purpose Road increasing the funding to 75% of maintenance costs. That section of road was not sealed at the time. 
• Earthquake strengthening of Thorndon Overbridge of the Wellington Urban Motorway: Image provided of the work to strengthen the 72 concrete columns supporting the Wellington Urban Motorway from the harbour over the Ferry Terminal, railway yards, Thorndon Quay. 
• Briefing to the incoming Minister of Transport - Jenny Shipley indicates critical traffic levels in Auckland: This noted that traffic on Auckland Harbour Bridge had increased 20% between 1989 and 1997, and on the Northern Motorway south of Albany (when at this time it terminated), it had doubled from 1989 to 1995.  It noted work was underway investigating and consulting on various major projects included:
• SH1 Albany-Puhoi (built in two stages)
• SH1 Harbour Bridge approaches (subsequently cancelled in favour of the Victoria Park Tunnel)
• SH18 Greenhithe Bypass (built as part of the Upper Harbour Motorway)
• SH18 Hobsonville Bypass (built as part of the Upper Harbour Motorway)
• SH20 extension to Richardson Road (built)
• SH20 extension to SH1 south (built)
• Bus only lanes on Northern Motorway (partially replaced with Northern Busway)
• Transit NZ winning the Institution of Professional Engineers New Zealand (IPENZ) environmental award: For the upgrade of SH12 through Waipoua Forest.
