Network Rail has been forced to apologise to road users after a third major system fault inside a fortnight.
Littleworth crossing at Deeping St Nicholas developed a fault on Friday morning and its barriers remained down for more than three and a half hours. Road traffic was forced to use alternative routes.
A spokesman said: “There was an issue with the signalling systems from 5.23 to 9.02 this morning.
“The barriers were down in order to protect safety and our team responded as quickly as possible and we apologise for the inconvenience.”
In the past fortnight there have been issues at Mill Green and Park Road level crossings which caused lengthy closures and serious road traffic congestion.
They were the latest in a string of problems which have affected several level crossings in South Holland since the GNGE line received a £280million upgrade last year.
South Holland District Council has written to Network Rail seeking assurances.
