New speed limit for Westbury

The introduction of a 40 mph speed limit on the A350 Trowbridge Road to the north of The Mead Roundabout, Westbury, is to encourage and reduce approach speeds into the recently constructed Millbrook Roundabout serving new housing development on the east side of the A350.

Since its construction there have been numerous reported instances of sharp braking due to excess speed on both the northbound and southbound A350 approaches to this junction. This is caused in part by the offset nature of the roundabout, with drivers failing to appreciate the sharpness of the deflection to the right on the northbound approach from Westbury, but equally the degree of offset to the left on the fast, straight, southbound approach.

Mitigation works to date have included additional signage on the northbound A350 approach and installation of bollards to emphasise the 'kick-over' of the carriageway to the right in this direction. The introduction of a 40 mph speed limit is considered an essential part of the package of highway safety measures necessary to combat excess driver speeds into this roundabout.
