    Abstract The Western Corridor Plan 2012 was adopted by the
    Regional Transport Committee on 15 August 2012. The
    Plan covers land transport services from Otaki in the
    north, down through to Wellington City, including
    east-west connections to the Hutt Valley.

    The Plan

    The Western Corridor Plan 2012 is consistent with the
    strategic direction outlined in the Regional Land Transport
    Strategy 2010-2040 and the Government Policy
    Statement on land transport funding 2012/13-2021/22.
    A background gap analysis report was developed to
    identify any issues facing the Western Corridor that were
    not covered by current planning documents. This report
    concluded that there were a few information gaps, but no
    significant planning gaps were found.

    Pressures and issues

    The Western Corridor is a primary commuter and freight
    route into and out of the Wellington region, connecting
    communities and commercial areas within the region and
    beyond. It also provides vital strategic access to the
    Wellington City CBD, Port and International Airport as
    well as the Wellington Regional Hospital. Significant
    residential and commercial developments in the Western
    Corridor are signalled to occur and freight volumes are
    predicted to double over the coming decades. SH1
    experiences peak period congestion at several hotspots
    including the Ngauranga Gorge, Paremata and south of
    Pukerua Bay. Off-peak congestion is a particular issue
    in Kapiti during weekends and on public holidays.
    Frequencies of rail services are limited by the single-
    tracked tunnels of the North-South Junction, and other
    track and signalling issues. East-west connections are
    another significant issue within the corridor, with capacity
    investigations of SH58 packaged with feasibility study of
    a new link road between Petone and Grenada. While
    various sections of the cycling network have undergone
    piecemeal investment, there is currently no continuous,
    safe cycling route through the Western Corridor. This
    limits growth of this mode for longer distance trips. Road
    safety continues to be a major issue with several safety
    black spots identified throughout the corridor.

    Key changes from the current plan

    The current Western Corridor Plan was adopted in April
    2006. This is a scheduled review. Since its adoption,
    there have been a number of changes to the context
    within which we are planning.


    Completed and committed work on the Kapiti and
    Johnsonville rail lines

    Introduction of the Wellington Road of National
    Significance (RoNS) as a priority for investment

    The draft Western Corridor Plan 2012 responds to
    these changes by incorporating the Regional Rail
    Package and the RoNS. It also outlines several
    projects and activities including investigating east-
    west connections as well as local road and walking
    and cycling improvements done in conjunction with
    the RoNS.
