Speed limits to be reduced on certain stretches of A4

Speed limits are being reduced on certain parts of the A4 in Slough next month after road safety concerns were raised.

Slough Borough Council (SBC) is making the change after the town’s A4 was identified as one of the fifty most dangerous roads in the UK by the Road Safety Foundation in 2016.

A spokesperson for the council added that in response to this, in 2017 the authority submitted a proposal to the Department for Transport (DfT) and in 2018 was awarded £1.7m.

The allocated funding was received by the council in March 2021.

The authority is now proposing various countermeasures to address concerns over road safety along the A4 and to ‘regulate driver behaviour’.

The proposals include implementing speed reductions on specific sections of the A4.

To align with the current 30mph limit that runs along the A4, the revised 30mph speed limit will extend along the A4 from its western borough boundary, the junction with Huntercombe Lane North/Huntercombe Lane

South, to the A4 Colnbrook Bypass.

This will be approximately 250 metres east of the junction of the A4 London Road and Sutton Lane.

The speed limit on the A4 Colnbrook Bypass is also reducing from 60mph to 50mph.

As part of the London Road/Sutton Lane road widening and junction improvement scheme, which was recently completed, a 30mph speed limit will also be enforced in two other locations.

These include Sutton Lane ‘from its junction with the A4 London Road to a point 57 metres north of its junction with the centre line of Trent Road’ and on London Road ‘from its junction with the southeast arm of the A4/London Road/Colnbrook Bypass junction to a point seven metres east of the west building line' of 602 London Road.

All speed limit changes will come into force from Monday, February 12.

A host of other road safety countermeasures are also being implemented as part of the A4 Safer Roads scheme.

The spokesperson added: “Additional road safety countermeasures including the removal of guardrails, average speed cameras, red light camera systems, road surface treatments and decluttering will be undertaken as part of the A4 Safer Roads scheme.

“The implementation of these measures aims to significantly reduce both the frequency and severity of collisions on the A4 in Slough.”
