West on the M4, then south
The run to junction 18 follows the same road as the Bristol journey and shares its early constraint through the Thames Valley. From Chieveley onwards the motorway is open and the pace steady.
Leaving at junction 18 puts the car onto the A46 towards Bath. It is a well-surfaced road with long straights and a small number of roundabouts, and it carries local traffic from Tormarton and Cold Ashton alongside through traffic.
The alternative approach by way of the A4 through Chippenham and Corsham is prettier and slower. It is worth taking on a leisure journey when the day allows it, and worth avoiding entirely when a table is booked.
