THREE more bridges in Kirklees are to be partly closed for safety reasons.
Council engineers have completed tests and ruled the bridges cannot continue to carry two-way traffic.
It means the Dalton Bank road bridge in Huddersfield, the Ravensthorpe railway bridge and the Calder river bridge, both in Ravensthorpe, will all have lane closures.
Temporary traffic lights will be brought in to operate one-way traffic across all three bridges.
The cost of repairs mean it could be months or years before they reopen.
The three are the latest in a series of bridges to be shut in the wake of European regulations which allowed heavier lorries on to British roads.
Bridges now have to meet more stringent loading standards.
The council has already brought in restrictions on bridges in King's Mill Lane, Whitacre Street at Deighton and Milnsbridge.
The Dalton bridge, owned by Kirklees Council, carries Dalton Bank Road over a disused railway at Colne Bridge. Checks found parts of the bridge structure are in very poor condition and are too weak to carry vehicles of any type. This would normally require the bridge to be closed to vehicular traffic but more tests have found the bridge closure could be avoided if the traffic is kept away from the weaker sections of the structure using robust barriers.
The single lane working will start on Wednesday, June 2, and will remain in force until the permanent bridge strengthening works.
The two bridges in Ravensthorpe are to be reduced to a single lane
The Calder river bridge is owned by British Rail Property Board and carries the Calder Road over the Calder River. The Ravensthorpe bridge is owned by Network Rail and carries Ravensthorpe Road over the Huddersfield to Dewsbury railway line.
The single lane restriction is an interim measure and will come into effect on Thursday, June 3, and will remain until the permanent strengthening work can be carried out in two or three years depending on funding .
