Works are set to take place on a key bridge above the A77 later this month. 

Amey is undertaking bridge parapet replacement on the Whatriggs Road Overbridge, two miles south of Kilmarnock. 

The works will run from Sunday, April 21 to Tuesday, May 28, and will improve the condition and safety of the parapet structure.

The works will take place at Whatriggs Road under a total closure of local authority road over the A77 from April 21 to May 28.

The road closure is to facilitate the safe demolition of the concrete cope. A signed diversion will be in operation.  

Traffic will be diverted along the A76 westbound to Bellfield Interchange where it will take the third exit on the roundabout to Queens Drive and turn left on to the B7072 (Hurlford Road).

Traffic will then turn left on to New Street and continue until Whatriggs Road and turn right at the roundabout on to Merrick Road. Traffic will then be able to turn left to join Whatriggs Road, where the diversion ends.  

There will also be alternating night-time lane closures on the north and south bound carriageways of the A77 from Wednesday, April 24 until Tuesday, April 30.  

Access for emergency service vehicles will be maintained throughout the works.
