Kingsway Tunnel rewire has begun

75 miles of cable– the equivalent distance of Liverpool to Leeds – will be installed as part of a major £7.5million project to rewire and replace the lighting in the Kingsway (Wallasey) tunnel.

The work started on Tuesday 3rd May is part of an on-going 10 year tunnels investment programme and is expected to take 18 months to complete, with the majority of work taking place overnight, causing minimal disruption to tunnel users.

The existing lighting will be replaced with more efficient LED units with a lifespan of at least 20 years, reducing Co2 emissions by around 450 tonnes per year and making up to £90,000 savings on the electricity bill per annum.

The existing electrical infrastructure will be replaced with modern cables which will be installed in the tunnel invert below the road surface. This will allow easier maintenance, minimising the need for the tubes having to be closed in the future – again maximising convenience for our customers.

Interesting facts

• 75 miles of cable will be installed

• 1600 light fittings will be replaced

• 6.5 miles of cable tray and baskets will be used

• 4.5 miles of steelwork and brackets will support the new installations

The Liverpool City Region approved the investment for the re-wire project in November 2015.

The 1.5 mile (2.4 km) Kingsway tunnel opened in 1971 and was built to accommodate the rise in traffic when the Queensway Tunnel, which was built in the 1930s to carry vehicles between Birkenhead and Liverpool, was unable to cope with the rise in post-war traffic.
