The Strand, Liverpool

An upgrade to a traffic signals junction was completed on The Strand in Liverpool, outside the famous Royal Liver Building. This traffic signals junction upgrade is part of a scheme by Liverpool City Council to renew the cities' highways and pedestrianised areas.

Liverpool City Council recognises the benefits of specifying NAL products across Liverpool including futureproofing against vehicular collisions and aiding future maintenance and upgrades. The improvements at The Strand, were completed by Graham Construction, using a range of NAL Traffic Signal Products to create a fully ducted system.

The NAL Retention Sockets were installed to house traffic signal poles within this busy junction.

The Retention Socket foundation will withstand all vehicular impacts to the poles, eliminating the need for future civils works during a pole replacement or upgrade. The socket also facilitates cabling the pole at ground level, removing unnecessary working at height risks. Furthermore, the sockets are positively ducted to the surrounding access chambers and controller cabinets.

The NAL Controller Cabinet Base (CCB) provides improved access to controller cabinet cables via an above-ground access door. Cables are easily fed upwards through the gland tray into the cabinet above, removing the requirement for a base seal, and simplifying the process of replacing or adding cables in the future.

For cable access, STAKKABox ™ Modula access chambers are used widely. These are specified throughout the UK, boast superior strength compared to traditional liner chambers. With a vertical loading of 40 tonnes, the STAKKABox is extremely durable. Their modular construction offers a speedy installation method and is available with pre-drilled duct access sections to assist positive ducting to the CCB and Retention Socket.

Composite Access Covers complete this system, which are available in multiple loadings to suit site requirements. The cover’s excellent non-slip resistance is the perfect solution for pedestrianised areas and busy locations such as The Strand.

This fully ducted system enabled contractors to install and cable swiftly and with ease, limiting the time spent on site and the duration of time this area was closed to pedestrians. This system also allows for a quick and effective process when maintaining and upgrading the site without the need for civils works.
