A4074 speed limits cut to 50mph: every section that changed

The main road between this district and Oxford is slower than it was a month ago. On 24 July 2026 new 40mph and 50mph speed limits came into force along almost the whole A4074 corridor, from the Heyford Hill roundabout at Oxford to Caversham. Oxfordshire County Council made the orders on 20 July.

Most of the route had been national speed limit, which is 60mph on a single carriageway. It is now 50mph. Two stretches have gone further and are 40mph.

The council did this knowing that most people who responded to it were against. It received 564 responses to the formal consultation. On every one of the ten sections consulted, more objected than supported, and on two sections the objection rate reached 65 per cent.

What changed, section by section

The council’s orders cover the A4074 itself and several roads leading off it. The changes are:

• Oxford, Heyford Hill: 40mph on the A423 Southern Bypass for 215 metres towards Kennington, on the A4142 Eastern Bypass as far as the Rose Hill roundabout, and on the A4074 for 415 metres towards Nuneham. All three were 50mph.
• Nuneham Courtenay to Berinsfield: 50mph on the A4074, including the Golden Balls roundabout.
• Berinsfield to Shillingford: 50mph on the A4074, replacing the 60mph national speed limit.
• Shillingford to Benson: 50mph on the A4074, replacing the national speed limit.
• Benson to Crowmarsh: 40mph from Benson south to the Benson Lane junction, where it had been 50mph, then 50mph on to the Crowmarsh roundabout, where it had been national speed limit.
• Wallingford bypass: 50mph on the A4130 from the Hithercroft roundabout to the A4074, replacing 60mph.
• Wallingford to Ipsden: 50mph on the A4074 from Crowmarsh Gifford south to Ipsden, replacing the national speed limit.
• Ipsden: 40mph on Church Lane and on the A4074 either side of that junction, both previously national speed limit.
• Ipsden to Woodcote: 50mph on the A4074 down to Cane End, plus 40mph on the B471 Oxford Road at Woodcote and 50mph on Reading Road, Exlade Street and Main Street at Checkendon.
• Cane End to Caversham: 40mph on the A4074, extending the existing Cane End 40mph limit south to Caversham. It had been 50mph.

Eleven separate orders were needed to do it, and they revoke or replace eleven older ones, some going back to 2011.

Objections outnumbered support on every single section

The formal consultation ran from 21 May to 20 June 2025. Notices went in the Oxfordshire Herald Series and the Oxford Times, and the council emailed Thames Valley Police, the fire and ambulance services, bus operators, South Oxfordshire District Council, Wallingford Town Council and fourteen parish councils.

Support was steady at between 25 and 28 per cent on every section. The narrowest gap was at Heyford Hill in Oxford, where 323 objected and 141 supported. The widest was on Ipsden to Woodcote, where 369 objected and 146 supported.

Thames Valley Police and the X40 operator both raised concerns

Nine further responses arrived by email, and two of them matter more than the rest.

Thames Valley Police told the council that reducing speed limits without physical changes to the road may not deliver the compliance or the safety improvement intended. The force pointed the council at the Department for Transport’s national guidance on setting local speed limits.

Thames Travel, which runs the X40 bus along the corridor, objected strongly. Its case was journey time and the cost of keeping to the timetable, which had been increased to three buses an hour in August 2025. It said it would withdraw the objection if the council accelerated three things: the Crowmarsh Gifford Benson Lane bus gate, northbound bus lanes on the Dorchester bypass, and turning the Reading Road junction at Woodcote into a compact roundabout.

Council officers went and measured it. They timed an off-peak X40 in each direction on 13 August 2025 and calculated the extra time the new limits would add. Their figure was about 79 seconds on the Oxford to Caversham run and about 57 seconds the other way. Thames Travel had estimated six to seven minutes. Officers concluded the impact was “not negligible” but low enough to approve the limits without the three improvements first.

Among parish councils, Berinsfield objected on the grounds that the existing limits were appropriate and the changes would lengthen journeys to work. Warborough objected strongly, saying no evidence had been provided and that the scheme does nothing about dangerous and anti-social motorcycling, which is its members’ main concern. Dorchester-on-Thames and Kidmore End supported the proposals. The county councillor for Benson and Crowmarsh supported them but said the benefits would not appear without enforcement.

The council’s answer

Officers made three arguments back.

On motorcycles, they accepted the concern but produced a figure: motorcyclists were involved in about 25 per cent of collisions on the A4074 over the latest five years, against roughly 20 per cent on Oxfordshire’s rural A roads generally. In other words, a little worse than average, not exceptionally so.

On the road itself, they judged most of the corridor to be “a lower quality A road”, with comparable Oxfordshire roads already at 50mph. Measured mean speeds were already at or below 50mph on much of it, which is the test the national guidance applies.

On the public response, the report is blunt. Accepting that the balance of opinion was predominantly objection, officers wrote that the detailed responses “for the most part raise generic concerns rather than ones focussed on the individual proposals”.

The whole scheme sits under the county’s Vision Zero road safety strategy, whose premise is that nobody should be killed or seriously injured on the roads. The council notes that the last review of speed limits on its A and B roads was completed 15 years ago. Funding came from the Vision Zero programme.

The Cabinet Member for Transport Management approved it on 9 October 2025. The orders were made on 20 July 2026 and came into force four days later.

What it means for you

The signs are up and the limits are live. If you drive the A4074 to Oxford or to Reading, you are now doing 50mph where you used to do 60, and 40mph on the Benson to Crowmarsh and Cane End to Caversham stretches.

Add about a minute and a half to an end-to-end run. That is the council’s own figure, from a timed bus journey rather than a model, and it is far below what the bus operator predicted.

Enforcement is the open question. Two councillors and a parish council raised it during the consultation, and the police raised it in a different form. The council has not committed to any new enforcement alongside the limits.

If you want the scheme reviewed, officers did commit to one thing: looking again at the 50mph stretch immediately south of the Woodcote turn, because of its collision history.
