Following repair work last year, a problem has been discovered with the specialist lime mortar used in the sandstone block joints on Bradley Bridge in Malpas.
The bridge wall was struck by a car, causing considerable damage, and required Old Malpas Road (B5395) to be closed.
Cheshire West and Chester Council’s cabinet member for environment, Cllr Karen Shore explained: “Following repairs to the bridge parapet, there is a problem with the lime mortar used in the joints.
“It has not gained sufficient strength for the wall to be strong enough. Expert advice has been sought and the Council is working jointly with our highways contractor to find a solution.”
Cllr Shore added: “We are now gathering information to establish the reasons for these problems. There are several options available to us to remedy the situation which we will investigate further.
“We apologise for the inconvenience caused to residents and motorists in the area.”
This means that the bridge, on Old Malpas Road, will now need to remain under traffic light control – with barriers in the channels – for several more months.
