Redoubt Road – Mill Road corridor project

Project overview

• Covers the 8.9km section of the Redoubt

Road-Mill Road corridor

• Starting at the State Highway One (SH1)

on and off ramps on Redoubt Road running

east then south along Redoubt Road to theRedoubt Road-Mill Road intersection

• The corridor continues south along Mill Road,

concluding south of Alfriston Road near the

intersection of Mill Road and Popes Road

• It also includes a short section along Hollyford

Drive to the north of Redoubt Road and

a portion of Murphys Road from a newintersection on Redoubt Road to Flat Bush

School Road.

Why is the project required?

• Changing land use, population growth

and planned housing developments will

increase pressure on local infrastructure

in south Auckland

• Significant crash hotspots along the route

make it necessary to improve the road’s safety

Improvements to the Mill Road corridor between

Manukau, Papakura and Drury are identified as

a priority in the Auckland Long Term Plan (LTP).

Special housing area

New industrial areas

Special Housing Areas

announced for the

area provide for 10,000

new homes – placing

pressure on the currenttransport network

• An estimated 10,000 new houses will be fast tracked in special

housing areas under the Housing Accord in southern parts of

Auckland, this includes 4470 houses in Flat Bush, and 1770

houses in Takanini

• A further 12,000 – 14,000 houses are anticipated to be

constructed in the Takanini, Opaheke, Drury and Karaka futureurban zone as indicated in the Proposed Auckland Unitary Plan

• New industrial areas in Takanini and Drury south will create

6,000 new jobs

• Traffic volumes will increase to a level more than the current

Redoubt and Mill Roads can cope with

• Congestion is already affecting parts of Redoubt Road andMill Road and traffic will almost double in 10 to 15 years.

Features and benefits

• A safer and more efficient route that can support future

growth in the area

• More reliable journeys by providing a four lane road with

more capacity and upgraded intersections

• Improved public transport infrastructure and services

• More reliable bus journey times, the ability to move

more people and remove constraints on the public

transport network by creating bus priority lanes through

Hollyford Drive and Redoubt Road intersections

• Improved travel time and safety for drivers, pedestrians and

cyclists

• New footpaths on both sides of Redoubt and Murphys Roadimproving pedestrian connectivity

• Safe pedestrian crossing opportunities at all traffic signals

• An alternative north-south corridor in case of major disruption

or emergencies on the other southern arterial routes

Safety

• Improves safety and provides for increases in traffic that

will come with significantly more people living in the area

and using this route

• Significant crash hot spots at a number of dangerous

junctions and curves along the route make it necessary

to improve the road alignment

• 283 vehicle crashes and four fatalities (2009-2013)• Without the upgrades there are expected to be further

safety issues and more traffic than the existing road can

cope with by 2026.

Environmental considerations and ecology

• Implementing a noise and vibration management plan

• Managing any soil contamination, stormwater runoff and dust

• Replacement planting and stream restoration

• Creating new wetland areas and habitats for local birdlife

• A pest eradication programme

• Monitoring environmental issues during construction

• On-going environmental monitoring after works are completed

• The route was selected at Puhinui Creek to avoid mature forest

• It crosses two areas of native forest via 17m and 23m high viaducts.

These will be built at Puhinui Creek gully and South Mill Road gully

• At least 22,000 sq. m of native planting

• Environmental monitoring during and after construction

• Mitigating effects by planting native trees adjoining to existing

bush areas• Monitoring mature trees for bat habitation before felling

• Minimise road lighting and where lights are necessary use

downward facing low pressure sodium lamps

• Rescue and relocate native geckos and skinks

• Provide fish passage and appropriate stream restoration where

culverts are built

• Retain a habit linkage beneath the Puhinui Creek Gully viaduct

during construction of piers which will remain after completion

A large number of routes were investigated and potential effects assessed before the final route was selected.A number of conditions are proposed to reduce or mitigate any long-term impacts:

Secondary and tertiary treatment

eg: raingardens, wetlandsand riparian buffers

Primary treatment

eg: filterstrips and swales

Stormwater treatment removes contaminants through an evironmentally friendly staged design.


8/11

Noise and vibration

Construction noise and vibration

• Noise and vibration will be produced from construction activities, laydown

areas and worksites.

What will be done about it?

• The team will comply with procedures set out in the New Zealand standards

6803:1999, Acoustics – Construction Noise

• This standard sets out limits and provides methods of predicting and

managing noise

• Before commencing any work, Auckland Transport will prepare a detailed

plan to show how the project will comply with the standards

Operational noise and vibration

• Once operational, the project will comply with procedures set out in the

New Zealand standards 6806:2010, Acoustics – Road Traffic Noise – Newand Altered Roads

• This is the accepted method in New Zealand to address road-traffic noise

• It provides performance targets and requires assessment of a number of

different options for noise mitigation

Mitigation options include

• Acoustic barriers

• Landscaping

• Use of low noise road surfaces (for example open graded porous asphalt)

• Dwelling modifications including double glazing and insulation

• The mitigation processes will change as the design progresses and

decisions are made on detailed design


9/11

Cycling and walking improvements

• On road cycle lanes for the length of the upgrade, varying between

1.5 and 2 metres wide

• Off road shared use paths for less confident cyclists and pedestrians

on one side of the length of the upgrade

• Advanced stop boxes for cyclists at intersections with traffic lights.

• Two metre wide footpath on both sides of Redoubt Road betweenSH1 and Hollyford Drive intersections

• A mix of footpaths and the shared use path will be provided for the

rest of Redoubt Road, Mill Road and Murphys Road

• Pedestrian crossings on all legs of intersections with traffic lights

(Hollyford/Redoubt, Diorella/Redoubt, Murphys/Redoubt)

• Safe crossing refuges in medians at Ranfurly Road and Alfriston Roadroundabouts

Public transport improvements

• Public transport improvements to the Mill Road Corridor will provide more

frequent and more reliable public transport services

• Bus priority facilities will be provided at the Hollyford Drive/Redoubt Road

intersection, including a dedicated right turn lane for buses turning out of

Hollyford Drive into Redoubt Road

• A new westbound bus lane is proposed between Hollyford Drive and SH1

intersection

• The proposed bus lane will allow buses to travel unimpeded between Hollyford

Drive and Diorella Drive, and between Diorella Drive and the motorway

• The frequency of bus services will increase which will provide a better level of

service for public transport users

• Improvements to bus priority facilities and frequency will enable a strong

integration with connector routes and local services

• Bus priority facilities will be provided at the Hollyford Drive/Redoubt Road

intersection, including a dedicated right turn lane for buses turning out of

Hollyford Drive into Redoubt Road
