King William Road Streetscape Upgrade

King William Road streetscape upgrade montage

The King William Road Streetscape Upgrade Project will deliver a safer, more connected and more attractive environment for all street users.

By upgrading the existing infrastructure between Greenhill Road and the bend alongside the popular Mike Turtur Bikeway, this project will transform King William Road into a safer, greener, and more accessible space for everyone - whether walking, cycling, using public transport, or driving - while supporting local businesses and encouraging more people to choose active transport.

The project upgrade will include:

  • Upgraded 4.0m walking and cycling shared path along the railway corridor (western side)
  • Improved southbound bicycle lane (1.5 metre) with 0.5 metre buffers
  • Two new pedestrian refuges – one located just south of Park Lane, and another at the bend opposite the Church of Resurrection
  • New kerb and water table (western side)
  • Full kerb-to-kerb road paving
  • New asphalt road pavement near Greenhill Road
  • New sections of kerb and water table (eastern side)
  • Upgraded footpath on the eastern side
  • New landscaping areas and 42 new trees (eastern and western sides).

The current bike box at the King William Road approach for right/diagonal turns will be maintained.

This important project upgrade is jointly funded by the City of Unley and the State Government through the National Road Safety and Special Local Roads grant programs.

Construction will be delivered by Beltrame Civil, commencing in mid-February and scheduled for completion by July 2026. 

 

Access during works

Works will be staged to minimise disruptions to local businesses and road users. Traffic restrictions and detours will be in place for safety reasons while works are undertaken. Beltrame will notify businesses and residents adjacent to the works area of any short-term temporary access changes. Traffic controllers will assist pedestrians and road users move safely around the works area.

Bikeway and footpath access

Bikeway and pedestrian detours will be in place for safety reasons while works are undertaken. Works will improve walking and cycling safety and comfort and provide consistent, high-quality shared paths and buffered bike lanes.

Project Impacts

To deliver the proposed streetscape improvements, changes to parking and traffic arrangements will be required. Eight of the existing 31 on-street parking spaces will be removed to accommodate the two new pedestrian refuges and footpath improvements to ensure they meet safety standards. Four parking spaces will be removed at the southern bend, one will be removed to accommodate a DDA compliant footpath realignment adjacent to the service station and three spaces to be removed to accommodate the new pedestrian refuge south of Park Lane. 

Mid-block traffic capacity will also be reduced during off-peak periods, with northbound traffic operating in a single lane. During peak periods, consistent with current arrangements, parking will be restricted on the western side to facilitate two lanes of traffic.

Project Background - Walking & Cycling Plan 2022-2027

Council’s Walking & Cycling Plan 2022-2027(PDF, 8MB) (W&CP) aims to continue delivering on Council’s vision of more people of all ages and abilities walking and bike riding for transport and recreation purposes.

The W&CP contains an Infrastructure Implementation Plan, which sets out the projects to be delivered over its five-year term (2022-2027). The King William Road Bikeway project (Mike Turtur Bikeway/Greenhill Road) is one of the identified priority projects. The project forms part of the popular Mike Turtur Bikeway and Wood-Weller Bikeway routes and provides an important walking and cycling connection between Unley and Adelaide.

Project Background - Community Consultation

The section of King William Road between Greenhill Road and the Mike Turtur Bikeway is a vital link for pedestrians and cyclists, recording over 850 bicycle movements and 1,650 pedestrian movements daily (May 2024 count). Existing facilities are sub-standard, with narrow shared paths, limited crossings, and on-road bike lanes positioned between busy traffic lanes.

Council initiated the design phase in 2020–2021 to address these issues and create a safer, more connected corridor. 

In September 2020, Council endorsed two streetscape concept design options for King William Road (Mike Turtur Bikeway / Greenhill Road) for community consultation (Resolution C0339/20): 

  • Option 1 – On-Road Separated Bike Lane; and 
  • Option 2 – Off-Road Shared Path. 

Consultation was undertaken on the proposed concept design options between 13 October 2020 and 4 November 2020, with the key aim to seek community opinion on the preferred design option. 

Strong community support for improvements to the current bicycle facilities along King William Road (Mike Turtur Bikeway/Greenhill Road) was received, with only four of the 93 survey respondents not supporting either of the options presented. Of those who supported the project, it was evenly split between the two options presented, with a slight preference for Option 2, as follows: 

  • 42 (45%) preferred Option 1
  • 45 (48%) preferred Option 2. 

Council considered this matter at its meeting held on 27 April 2021 and endorsed Option 2 to progress to detailed design (Resolution C0489/21). 

Detailed design was undertaken by an engineering consultant, which commenced in 2021-2022. The detailed design includes Department for Infrastructure and Transport (DIT) approval for traffic signal changes at the King William Road and Greenhill Road intersection and was completed in March 2024. 

The main difference between the endorsed concept design (2021) and the final detailed design (2024), is the inclusion of an enhanced pedestrian and bicycle refuge at the bend opposite the Church of Resurrection. This was a key outcome from the community consultation feedback to review the concept design of the proposed bicycle refuge to allow for pedestrians and additional trees.
