A set of faulty traffic lights which have made a junction “very dangerous” for motorists have been temporarily fixed.

The lights at the junction for Willian Road, Norton Way South and Baldock Road in Letchworth GC were reported to be constantly showing green on Friday.

An engineer attended to fix them but was forced to return the following day after the lights were constantly showing red.

This morning (Monday) an engineer attended the lights for a third time after they were again constantly showing red.

People who have witnessed the problem first-hand have been voicing their concerns to the Comet on social networking site Twitter.

Richard Palmer, headteacher of St Christopher School in Letchworth GC, said: “Lights at A505/Willian Way/Norton Way South all over the place. Just seen a near miss that would have been awful.”

@Melanie858 wrote: “Crazy traffic lights this morning (Saturday) at William Way/Baldock Road – everyone going on red lights and it’s very dangerous.”

A spokesman for Ringway, which looks after Hertfordshire County Council’s traffic lights, said that their engineers replaced a corrupted motherboard on the lights on Saturday and have ordered a new traffic sensor today, which should arrive shortly.

She added: “While we are waiting for the new parts to be delivered the lights will operate on a timer rather than by using a sensor that detects traffic.”
