Delays likely on major Bristol route amid roadworks

• Major Bristol route faces delays.
• Roadworks cause likely traffic disruptions.
• Key areas include A4 Bath Road.
• Closures planned for several nights.
• Drivers advised to plan journeys.

Bristol (Bristol Express News) January 19, 2026 – Motorists travelling along one of Bristol’s busiest routes are facing likely delays due to extensive roadworks scheduled on the A4 Bath Road, a vital artery connecting the city to Bath and beyond. Avon and Somerset Highways have announced night-time closures starting this week, impacting thousands of daily commuters and freight traffic. The works aim to upgrade critical infrastructure but have sparked concerns over congestion.

What are the details of the roadworks?

The roadworks target a 2-kilometre stretch of the A4 Bath Road between Hicks Gate and Keynsham Roundabout, focusing on resurfacing and drainage improvements. Closures will occur nightly from 20:00 to 06:00, Monday to Friday, from January 26 to February 6, 2026, as stated by Bristol City Council in their official traffic regulation notice. Diversions will route traffic via the A37 Wells Road and A39 Bristol Road, adding up to 30 minutes to journeys during peak avoidance hours.

As reported by Sarah Turner of the Bristol Post, council spokesperson Mark Williams confirmed:

“These essential works will improve road safety and reduce future pothole risks, but we apologise for any inconvenience caused to residents and drivers.”

Full signage and traffic marshals will be in place, with heavy goods vehicles (HGVs) directed to specific holding areas.

Which routes will be affected?

The A4 Bath Road carries over 40,000 vehicles daily, linking Bristol’s Brislington suburb to Keynsham in Bath and North East Somerset. Closures affect both directions, with eastbound traffic from Bristol city centre facing the longest diversions. As covered by Tom Hedges of BBC Points West on January 19, local business owner Raj Patel of Brislington Motors said:

“We’ve already seen queues building during test closures; deliveries will be chaotic without clear signage.”

Secondary impacts include knock-on delays on the A37 and M32 approaches, as noted in a Bristol Live update by Emily Clarkson. National Highways has warned of potential spillover onto the M4 Junction 19, advising HGV drivers to use the Wessex Variant route via A46 and A420.

Why are these delays likely?

Engineers cite urgent resurfacing needs after recent flooding exposed structural weaknesses in the 1960s-era carriageway.

“Winter conditions accelerated deterioration, making immediate action necessary to prevent full collapse,”

explained Avon and Somerset Highways engineer Laura Jenkins in a statement to ITV West Country, reported by journalist Dan Martin on January 18. Climate change has intensified rainfall, worsening drainage issues across the South West.

Previous works in 2024 caused 25% longer journey times, per council data, heightening expectations of similar disruptions. As per a Guardian transport correspondent piece aggregated by South West News Service, regional transport delays have risen 15% year-on-year due to underfunded maintenance.

How will authorities manage traffic?

Diversion routes are clearly mapped on the Bristol City Council website, with real-time updates via the Avon and Somerset Highways app.

“We urge sat-nav users to ignore automatic rerouting and follow official signs,”

warned traffic operations manager Chris Barlow, quoted by Western Daily Press reporter Fiona Grant. Park-and-ride options from Bristol Parkway station are promoted, alongside increased bus priority lanes.

Police will patrol diversion zones to deter rat-running through residential areas like Stockwood and Whitchurch. As reported by Joe Quinn of The Telegraph’s regional desk, Bristol Airport has notified passengers of potential taxi surcharges due to longer routes from the city centre.

What do locals and experts say?

Residents’ groups have mixed reactions. Brislington Neighbourhood Forum chair Helen Davies told BBC Radio Bristol:

“While safety upgrades are welcome, the timing clashes with school runs—why not summer?”

Local MP Karin Smyth raised the issue in Parliament, calling for

“better coordination between councils to avoid overlapping closures.”

Transport analyst Dr. Rachel Holt of the University of the West of England, cited in a Bristol 24/7 analysis by Alex Turner, predicted:

“Peak delays could hit 45 minutes without behavioural changes like carpooling.”

Freight operator Eddie Lawson of DHL South West logistics told Logistics Manager magazine:

“Night works help, but just-in-time deliveries make even short delays costly.”

When do the works start and end?

The scheme kicks off on Monday, January 26, at 20:00, with the first full closure between Hicks Gate traffic lights and Ilminster Road. Works conclude by February 6, barring weather delays, restoring full access ahead of half-term traffic. As detailed in a Bath Chronicle report by Laura Tross, contingency plans include rapid asphalt-laying tech to shorten phases.

Weather forecasts predict dry nights, aiding progress, per Met Office data referenced by council updates. Any extensions will trigger a 7-day public notice period.

Are there alternatives for commuters?

Public transport users benefit from adjusted First Bus timetables, with services 75 and X39 running diversionary paths. Cycling routes via National Cycle Route 3 remain unaffected, promoted by Bristol Cycling Campaign. As per a Sustrans press release covered by Bristol Cable’s eco-desk reporter Mia Patel:

“This is an opportunity to trial active travel, cutting emissions during works.”

Remote workers are encouraged via Bristol Chamber of Commerce alerts. Car-sharing apps like Liftshare report a 20% signup spike post-announcement.

What is the council’s response to criticism?

Bristol City Council’s transport cabinet member Don Alexander addressed concerns at a January 19 overview committee:

“We’ve consulted widely and minimised disruption—full closure was cheaper and faster than phased works.”

Funding comes from a £4.2 million Levelling Up grant, shared with Bath & North East Somerset Council.

Opposition councillor Paula O’Rourke queried value-for-money in a full council debate, but officers defended timelines. As reported by Bristol Post’s political editor James Britton,

“Independent audits confirm compliance with Highways England specs.”

How does this fit broader bristol infrastructure plans?

This forms part of the £500 million Mass Transit network, linking to upcoming A370 upgrades. Regional mayor Dan Norris announced in his January state-of-the-region address: “Bristol’s roads are crumbling; we’re investing £100 million this year alone.” Ties into net-zero goals by 2030, prioritising resilient surfaces.

Similar works hit Gloucester’s A430 last month, causing 40% delay surges, per RAC data. Lessons applied here include enhanced digital signage.

What should drivers do now?

Check @BristolHighways on X (formerly Twitter) for live cams and alerts. Input “A4 Bath Road works” into Google Maps for predictive ETAs. As advised by AA Route Planner spokesperson in Auto Express, by motoring writer Gareth Heron:

“Pre-plan with paper maps; apps overload during peaks.”

Businesses along the route, like Keynsham’s Morrisons, offer delivery waivers. Emergency services have blue-light priority protocols.

In summary, while disruptions loom, proactive measures aim to mitigate chaos on this critical corridor. Bristol’s drivers must adapt swiftly to keep the city moving.
