More than 1,600 street lights have been replaced with energy efficient ones at a UK motorway.
The improvement works took place on the M62 near Huddersfield and Halifax – junction 22 to 25 – and the M621 near Leeds.
The new lights are believed to be 53% more efficient, saving the equivalent energy of powering 20,000 homes and 389,000 loads of washing.
The Highway England’s project is also expected to reduce more than 700 tonnes of carbon a year.
A remote monitoring system has also been installed, which allows contractors to remotely control the lights.
They worked with specialists to adapt technology used for architectural ornamental lighting, such as monuments and halls, for use on motorways and major A roads.
Mark Ramsden, Highways England Service Delivery Team Leader for Yorkshire and Humber said: “This is a true example of taking innovation from another industry, modifying it for the highways sector and improving value by locking in safety, customer, cost efficiencies and environmental benefits.”
