Northern Busway, Auckland

Passengers boarding a Auckland Transport Northern Express service operated by Ritchies Coachlines.

The Northern Busway is a segregated busway with dedicated park & ride facilities along State Highway 1 in the north of Auckland, New Zealand, linking the North Shore with the north end of the Auckland Harbour Bridge. It reduces travel times for from around one hour by car during peak hours to about half an hour by bus,[1] and within the North Shore, where it is the spine of the bus-based public transport system.

History

Concept, Design, and Construction

Smales Farm station, shortly before the busway opening.

Concept design for the busway was developed by MRCagney (formerly McCormick Rankin Cagney), with detailed design and consultation completed by Mario Madayag Architecture, Jasmax, Beca Group, Opus and Connell Wagner. Fletcher Construction was responsible for construction. Akoranga, Smales Farm, and Sunnynook stations were built by NZ Strong Construction.[2][3][4][5]

Difficulties encountered included the nearby residential areas, the predominantly soft ground, and environmental efforts to protect dotterel breeding grounds. Construction employed around 300 people at its peak, with around a million man-hours being invested, including shifts during 512 nights.[5][6]

Operation

The busway was officially opened in February 2008 after several years of construction, though the two northernmost stations had been operating since December 2005 using the normal Northern Motorway lanes.[7][8] It was credited with having reduced peak traffic on the Northern Motorway by around 500 cars each rush hour one month after the opening,[9] and about 39% of passengers on the Northern Express bus service had never used public transport before.[5] The busway was initially used by 70 buses per hour during peak time.[6]

With its completion, the busway has started to raise interest both amongst technical experts and other groups. There have been advertisements filmed at the bus stations, and requests to allow filming of car commercials, denied as being inappropriate for a public transport facility, and interest from overseas movie location scouts wanting to use the 'futuristic' stations as backdrops.[10]

In 2008 the busway received the 'Shell Bitumen Excellence Award for a Major Roading Project' and the 'Roading New Zealand Supreme Award'.[11] In June 2009, it received the Ingenium 'Excellence Award' (in the category for projects above NZ$2 million construction cost).[12]

In June 2010, the busway carried its 5 millionth passenger. Patronage has kept rising, and in 2010 the busway was estimated to remove the equivalent of about 5,100 cars in the morning peak, with 80 buses per hour during peak times.[13]

By mid-2011, frequency of the Northern Express had risen to every three minutes during the morning peak hour, five minutes during the 'shoulder peak'.[14]

Funding

The busway became fully operational in 2009, with some final sections being completed with little publicity, for around NZ$290–294 million: $210 million for the busway and $84 million for the stations.[15][16] The project was funded by Transit New Zealand, ARTA and the Auckland City Council and North Shore City Councils.[6]

Infrastructure

Constellation Drive Park & Ride station.

Busway

The busway has two lanes for 6.2 km[17] running parallel with the SH1 motorway from the Constellation station at Constellation Drive/Upper Harbour Highway interchange to Akoranga station at the Esmonde Road interchange,[18] from where a one-way southbound bus lane extends a further 2.5 km to south of the Onewa Road interchange, where it merges with the motorway for the Harbour Bridge[5]

Its use is limited to buses of 25+ seat capacity, emergency and maintenance vehicles.[15] The busway has been designed for possible use by car pools[17]

Bus stations

The busway includes five dedicated stations, some with extensive park & ride car parks. Feeder bus services serve the stations, allowing transfer or continuing on the busway.

The stations are (south to north):[3] [2]

Akoranga - the footbridge leads to the western side of the motorway.

All stations provide shelter and cycle parking and were designed with public safety in mind, such as with glass walls, low planting, night lighting and CCTV to enhance security.[17]

Other structures

Major related structures are the new Esmonde Interchange (including large-scale improvements for general traffic) and Tristram Avenue Viaduct, which crosses the often-congested Tristram Avenue via grade separation. The viaduct has 12 spans of 30 m each, with the foundation piles being 1.5 m thick.[18]

Electricity transmission cables

Cable ducts were placed beneath the busway during the construction in 2005, to provide for the future installation of electricity transmission cables. The cables installed in these ducts during 2012 and 2013 form part of a major upgrade to the security of supply to North Auckland and Northland.[19][20]

Plans

Sunnynook, the smallest of the five stations.

An extension towards Orewa in the north is being debated for the long-term future. It was originally expected to cost around NZ$500 million,[16] although the success of the scheme has now sparked potentially more extensive schemes for between NZ$700 million and NZ$1.2 billion to at least Silverdale, with up to five tunnels and seven bridges, including a motorway flyover between Constellation Drive and Albany stations. New stations are proposed at Rosedale, Redvale and Silverdale.[21]

Plans include the suggestion of extending the rail network to the North Shore, as the design parameters allow for conversion to heavy rail.
