How to find us during road closure 🚧

Attention Knockhill Customers this week.

If you are coming to Knockhill this Monday to Friday, the road to Knockhill from Dunfermline/Edinburgh/Junc 4 will be closed from Monday 2nd June to Friday 5th for re-surfacing.

If you are travelling from North of the Circuit, from Fife, Edinburgh or the Borders, then the easiest, and quickest, route to Knockhill is to make your way on to the M90, exit via junction 6 at Kinross, and follow the brown Knockhill signs. Travelling from Glasgow and the West is open as normal, so head over the Clackmannanshire Bridge and follow the signs.

If you arrive at the Road Closed signs, then follow the Fife Council diversion signs via Saline, Blairingone to Powmill, and this will bring you into the venue from the North. Please allow an extra 15 - 20 minutes if you are diverted.

The road will be open as normal for next Saturdays's Bike Track Day and rally experiences, and Sunday's Hot Hatch & Scottish Ford Live.
