Police have warned people to not cross Elland Bridge after it began to collapse in the early hours of Tuesday morning.
A Calderdale Valleys Police spokesperson said: “We are receiving reports that despite significant barriers been put in place by Calderdale Council that a small minority are still crossing the bridge at Elland.
“As has been reported, this bridge is at serious risk of collapse and is clearly impassible.
“Please do not attempt to cross the bridge as these irresponsible actions force us to divert officers from other flood relief activities that they are undertaking.”
The leader of Calderdale Council Tim Swift has said the bridge will be closed ‘for the forseeable future’.
Councillor Swift said engineers from the council and the Canal and River Trust, who own the bridge, have been onsite and it is likely extensive repairs will be needed.
“Due to the location of the Bridge, it’s difficult to provide diversion routes, but we are working with our partners to identify a temporary solution,” he added.
“The collapse of the bridge at Elland, and the damage to the A646 in the Upper Valley, means that only essential journeys should be made around these affected areas.
“We need to keep roads clear for emergency services and recovery vehicles.”
