Safety improvements at the SH1 Main South Rd/Tennyson St intersection are now being investigated as part of a wider corridor study to identify and address safety and access issues along SH1 in the Rolleston area.
After consultation with the public and key stakeholders, design reviews and safety workshops, a design for these intersections has been chosen.
Option 5d was chosen as the best option to meet the project objectives. This is because of its effectiveness in resolving the existing conflicts, simplicity, cost effectiveness, constructability, minimising impact on existing businesses, providing the capacity to incorporate future proofing, and its fit with stakeholders’ preferences.
The SH1/Tennyson Street and Brookside Road intersections have had a number of crashes in the last decade and records show there is a pattern of crashes involving traffi c turning right out of Tennyson Street on to SH1 towards Christchurch. The Kidman Street Extension to Rolleston Drive was completed in July 2011. The priority at the Brookside Road and Byron Street intersection has been changed so Byron Street is the main road. This reduces traffic accessing SH1 from Brookside Road as it acts as a local road together with Kidman Street that links to Rolleston Drive and the traffi c signals on SH1. The issues with the current Tennyson Street/SH1 and Brookside Road/SH1 intersections are:
The new design for the Tennyson Street/SH1 and Brookside Road/SH1 intersections (option 5d) includes a deceleration lane along the left slip lane for left turning vehicles into Tennyson Street. It maintains the existing left turns in and out of Tennyson Street and maintains the existing priority of the Tennyson Street and Dick Roberts place interesection. A pedestrian overpass to connect Rolleston to the railway and developments south of SH1 is also being considered.
This project is on hold until funding is available.
