Working in partnership with the Royal Borough of Kingston, VolkerHighways has completed a major street lighting upgrade scheme along the 80-metre-long dual carriageway Horsefair Tunnel.
The project, which was completed two weeks ahead of schedule, has involved removing the existing aged lighting and replacing with LED future-proofed lighting, with a 40-year life expectancy.
Following structural inspections carried out in October, it was determined that a full retrofit and redesign was required. Under a single-lane directional closure, carried out across 35 nights, the scheme involved the removal of all 260 existing lanterns and the installation of 19 269W and 21 69W LEDs.
It is expected that switching to LEDs can reduce energy consumption by around 65%. This is supported by the chosen 69W lighting which will be used during darkness and 269W during daytime.
The scheme has required a high-level of expertise due to its complexity. As principal contractor, VolkerHighways worked closely with specialist lighting contractors, under a large diversion route, keeping traffic flowing throughout.
Efficiency savings were achieved for the Royal Borough of Kingston by utilising the traffic management set-up to undertake additional works outside the original scope, including bridge expansion and cable repair works.
“Horsefair Tunnel lighting improvement scheme was many years in the making due to its complexity required to enable its success. We are proud to have completed this project to a high-quality and ahead of schedule, while providing efficiency savings for our valued client. Thank you to all stakeholders involved in securing its success.”
