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.

1996: National Roading Programme: Auckland/Northland NRP news

 The Auckland/Northland newsletter for the 1996 National Roading Programme of Transfund NZ.

It was noted that 46% of spending in Auckland was road maintenance.  The newsletter has a comprehensive list of all state highway and local road projects funded, including investigation and design in Auckland and Northland. Notable in this NRP was approval of funding for the extension of the Northern Motorway from Albany to Silverdale, which continued to Orewa until funding to proceed was suspended in the early 2000s until tolling was authorised for the Orewa to Puhoi section. Investigation and design also began for a series of other major motorway projects in Auckland, including extensions of SH16 and the Upper Harbour Motorway SH18.

Major committed projects included:

  • SH16 Northwestern Motorway Rosebank and Patiki Rd Interchange construction
  • SH20 Southwestern Motorway extension Quarry Rd (Mangere Bridge) to Massey Rd (Papatoetoe), connecting the Mangere Bridge to the Pupatoetoe Bypass, and towards the Airport to George Bolt Memorial Drive
  • Auckland City Southeastern Arterial (Church Street-Mt Wellington-Pakuranga Motorway).

New construction projects included:

  • SH1 Northern Motorway extension Albany to Silverdale
  • SH1 Auckland Harbour Bridge seismic upgrade
  • SH1 Orewa Bridge replacement (pre Silverdale-Puhoi extension of Northern Motorway)
  • SH1 Puhoi-Wellsford passing lanes
  • 16km of seal extensions in Rodney District
  • Wairau Road intersection upgrades in North Shore
  • Thirteen seal extension projects in Far North District
  • Eight seal extension projects in Whangarei District

New investigation and design work was funded for future projects:

  • SH1 Warkworth-Dome Alley improvements
  • SH1 Schedewys Bypass
  • SH1 St Marys Bay/Victoria Park Viaduct widening/tidal flow (this did NOT proceed and was replaced by the Victoria Park Tunnel)
  • SH16 Northwestern Motorway Brighams Creek extension
  • SH18 Upper Harbour Motorway
  • SH20 Southwestern Motorway extension Hillsborough to Dominion Road
  • SH1 Southern Motorway Greenland Interchange upgrade
  • SH1 Southern Motorway Otahuhu Interchange upgrade
  • Auckland ATMS
  • Orewa Link Road to connect to Silverdale-Puhoi extension of Northern Motorway

In Transit - September 1995 - Auckland Airport eastern access

 

In Transit September 1995 No. 67

Review of winter road closures, launch of state highway review

Quality Assurance in road markings

Stock effluent, London visitors discuss accessible transport

Black spot safety audits reduce crashes

This edition of In Transit highlights the Auckland Airport eastern access route which was under construction at the time (now SH20B).  The entire route cost $17m at the time and was due to finish in March 1996. The other most notable point was the benefits of black spot safety audits in reducing crashes, noting 2700 crashes had been prevented since 1985, as 61% of black spots identified had been upgraded with low cost solutions such as improved road markings, signs and lighting.

Other points in this edition are:
  • Review of the winter road closure policy for state highways
  • Launch of the State Highway Review (which reviewed which roads should become state highways and which should be cancelled as state highways)
  • Quality Assurance in road markings
  • First stock effluent disposal facilities trialled on two state highways
  • Visit by British accessible transport experts
  • Decision to construct slow vehicle lanes on both sides of SH29 Kaimai Ranges
  • Discussion of a private proposal to build the Te Puke Bypass, upgrade Pyes Pa Road and Route J. Ultimately Te Puke Bypass would become a state highway toll roads, Pyes Pa Road became a state highway and was upgraded, and Route J funded as part of the National Roads Programme.

NLTP 1996 - Auckland local road construction funding

NLTP 1996 - Auckland local road safety construction funding

NLTP 1996 - Auckland State highway safety construction

NLTP 1996 - Auckland State highway construction and passenger transport funding

In the final of the NLTP 1996 regional newsletter series, is Auckland, which had by far the greatest funding allocation.  $184 million was allocated for Auckland and Northland. This newsletter mostly focuses on Auckland.  Key Northland projects include completion of the sealing of SH12 through the Waipoua Forest and local road seal extensions.  The output classes with the greatest share of spending were state highways.

Key state highway projects were commitments to complete:
  • SH16 North-Western Motorway Rosebank interchange (providing eastbound off and on-ramps at Rosebank Peninsula)
  • SH16 North-Western Motorway Western Springs to Newton widening
  • SH20 South-Western Motorway extension connecting Mangere Bridge to the Papatoetoe Bypass and Kirkbride Road (to connect to George Bolt Memorial Drive)
  • SH1 Southern Motorway widening Papatoetoe-Manukau-Manurewa 6-laning
Largest local road projects were:
  • Auckland City's South East Arterial project (now the South Eastern Highway) from Church St to Pakuranga Bridge (a scaled down version of a planned motorway from the SH20 to Pakuranga and along the former south-eastern corridor.
  • Completing the sealing of former SH16 (which is now once again SH16) at Cleasby's Hill.
In addition are a number of intersection and local street upgrades to improve capacity and safety.

Notable was funding granted for design of notable major projects:
  • Albany-Puhoi extension to Northern Motorway, between Albany and Orewa (subsequently built)
  • SH20 Hillsborough Road to Dominion Road extension (subsequently built beyond to Mt Roskill)
  • SH1 Victoria Park widening (subsequently did not proceed but was replaced by the Victoria Park Tunnel)
  • SH1 High occupancy lane extensions in advance of the Northern Busway (between Esmonde Road and the Auckland Harbour Bridge)
  • SH1 Schedewys Hill Bypass (superseded by the Puhoi-Warkworth motorway)
  • SH1 Kawakawa Bypass (not yet built)
  • SH1 Kamo Bypass (subsequently built)

In Transit December 1994

In December 1994, Transit NZ was reporting on reconstruction over the past year on highways in Milford and Haast due to rainfall. However, it was able to fund reconstruction and restoration from its existing funding under the National Land Transport Programme.  It notes over 100km of road had been rebuilt or repaired, following massive rock falls and slips demolishing large segments of highways and burying bridges.  Christchurch was also hit, but it was noted that major projects were not badly affected.

This issue also reports:
  • Construction of the Eland-Glengarry realignment on SH5 (Napier-Taupo Road) realigning 5km of state highway (and having a BCR of 7.6) 
  • Decision to build passing bays in Homer Tunnel, partly because large tour coaches find it difficult to pass in the tunnel. The passing bay proposal had a lower BCR than the funding threshold, but funding was approved due to its strategic importance to tourism.
  • Series of projects in Wellington including realignment of 1km of SH58, Martinborough flood relief bridge, Newland flyover construction commenced, Whangamoa Hill deviation on SH6 Marlborough underway, design of the Stoke bypass commenced, planning for bypasses of Ruby Bay and Motueka.
  • Major public consultation on options for SH1 between Porirua and Waikanae, these were in response to Transmission Gully not being able to be funded in the foreseeable future.  Noting Transmission Gully was estimated to cost $150m at the time and not expected to be funded for at least 15 years (2009).  However, the Transmission Gully route was still to be designated to protect it from development and to give landowners certainty. 
  • All Northland state highways will be sealed by 1996 following a contract to seal the last 10km of SH12 through Waipoua Forest, noting special root bridges were designed to avoid damaging kauri tree roots.
  • Contract awarded to realign the Waiau Bridge and approaches in north Taranaki on SH3.
  • Waikato projects including four-laning of Fairy Springs Road in Rotorua, sealing of the last 6km of SH25 Coromandel, Pokeno bypass, Mangatawhiri Bridge realignment and Tamahere deviation (Waikato Expressway).
  • Auckland projects including completion of the Bombay Hills motorway extension, commencement of construction of the Mangere motorway (connecting the Mangere Bridge with the Papatoetoe Bypass and including the Airport motorway connection) and completion of the Upper Harbour highway interchange on the Northern Motorway.
