Lancashire County Council has closed Spring Gardens Road in Colne until repairs can be made to a retaining wall which supports the carriageway above Colne Water.
Traffic management has been in place since last summer to keep vehicles off part of the road to reduce the load on the wall. However, repeated acts of vandalism to the temporary traffic lights and cones has made it impractical to keep them in place, and the road will now be closed until the wall is repaired.
David Hurford, Lancashire County Council bridges manager, said: “We put traffic management in place last summer when the structural problems with the retaining wall emerged to limit any further damage until it could be repaired.
“Unfortunately this has repeatedly been vandalised with the cones being frequently thrown in the river, and has become worse lately with the traffic lights being damaged on a number of occasions over recent weeks.
“The amount of time and money we can spend replacing the traffic management has reached its limit, and we feel our only option is to close Spring Gardens Road to traffic until the repairs have been made. We have been discussing a repair scheme with the Environment Agency over recent months and hope to be in a position to do the work later this summer. In the meantime we will continue to monitor the condition of the wall.”
A diversion is signed via Shaw Street, Bridge Street and Green Road.
