The A78 trunk road will be closed for the second weekend of resurfacing work from 8pm Friday 26th to 6am Monday 1st March, from the junction of the main road and the Haylie Brae A760, to south of Largs Yacht Haven. The diversion is via the Haylie Brae A760, and B roads to Dalry, and the back of West Kilbride, or the Ardrossan Bypass, depending where you are travelling from/to.
Local access will be available to LYH. The Haylie Brae itself will be open (it's the diversion route!) EXCEPT overnight Thursday 25th February, between 8pm and 6am, ahead of Closure 2. This will involve a single lane closure on the A78 with a convoy system in operation.
