Roscommon Road, Manurewa – Route optimisation Roscommon Road, Manurewa – Route optimisation

Proposal status: closed 14 August 2018

Reference number: NOP1718-058

We're proposing changes in your area

We are proposing to install a two lane extension and clearway (3pm to 7pm, Monday to Friday) on Roscommon Road, from Browns Road to Moncrieff Avenue. This will increase southbound capacity along Roscommon Road. The proposed changes include:

  • Two lane extension from 320-354 Roscommon Road.
  • Installation of a clearway (3pm to 7pm, Monday to Friday) on Roscommon Road from the intersection with Browns Road to 366 Roscommon Road.
  • Installation of No Stopping At All Times restrictions along the intersection of Burbank Avenue and Roscommon Road.
  • Installation of new bus stop markings and a concrete bus hard stand outside 346-348 Roscommon Road.
  • Changes to road markings and signage.

Why the changes are needed

The current layout of Roscommon Road contributes to southbound congestion during peak traffic.

Proposal outcome

This project will proceed without changes to the next stage of detailed planning. A summary of the community feedback we received and answers to questions and concerns is below.

Feedback received

  • Concern that allowing for increased traffic on Roscommon Road will make the road more dangerous, particularly as vehicles are often travelling above the speed limit. Currently, there is existing downstream congestion on Roscommon Road that causes southbound delay where vehicles are forced to merge a short distance after Browns Road intersection which blocks cars turning out of Finlayson Ave and Burbank Ave. The long queues will likely remain and the severity of traffic will not reduce during the pm peak.
    The purpose of this proposal is to alleviate the traffic congestion issue happening at the existing merge by moving the conflict point away from the turning movements for the two side roads (Finlayson Ave and Burbank Ave) and improve operations of the traffic signals at Browns Road. Outside of the clearway operating hours (3pm to 7pm), vehicles are permitted to park on the clearway kerbside lane. This reinstates the road layout to existing operating conditions for the majority of the day.
  • Suggestion to include design features in the proposal that make the road safer for pedestrians. We acknowledge your concern regarding pedestrians and providing safer crossings, however our site observations show that there is a low demand for pedestrians along this section of Roscommon Road. We would like to reiterate that the two lanes will only be effective for three hours of the day during the pm peak hours; most other times of the day, including weekends, the road arrangement will be as it is currently. We will continue to monitor this corridor after the implementation of this project for any improvements but at this stage the current proposal is the most appropriate arrangement for this section of road.
  • Suggestion to shorten traffic light phasing to allow improved vehicle movement on Roscommon Road during peak traffic. Additional green phasing on Roscommon Road southbound would unlikely reduce the southbound delay due to the downstream blocking on Roscommon Road. After implemention of this project, we will continue monitoring Roscommon Road and review timings and how the intersections operate.

Next steps

This work will happen between August 2018 and June 2019, but we will let you know if there are further changes or delays.

Our contractors will send notices to affected residents 48-hours prior to construction starting.
