A road traffic collision has led to rush-hour delays on the A77 tonight.

Motorists heading southbound face being held up on the approach to the Bellfield Interchange at Kilmarnock.

Traffic Scotland reports that one of the lanes is blocked with traffic "very slow" on the approach to the busy interchange.

A tweet issued a few minutes later confirmed that all lanes were restricted for up to 30 minutes.
