When traffic problems on the M4 are discussed, the problems of traffic jams during peak periods between junctions 44 and 46 tend to be overlooked, though not by those of us travelling along those roads. The reasons for traffic hold-ups include vehicles changing lanes and vehicles entering and leaving the motorway—the same reasons that we have hold-ups everywhere else on the M4. I'm requesting signage on the M4 to direct traffic accessing the enterprise zone to use junction 45 rather than junction 46, because junction 45 is a superior junction and it does have the advantage that traffic, on doing that, does not have to slow down on the motorway in order to join the roundabout.
