Bristol (Bristol Express News) June 18, 2026 – A man in his thirties has been arrested after Avon and Somerset Police closed a significant section of the M5 motorway near Bristol for more than four hours on Sunday night, causing widespread disruption to motorists and travellers across the region.

How Long Did the M5 Closure Last and Which Junctions Were Affected?

As reported by BBC News, the motorway closure began at about 20:00 BST on Sunday and blocked the M5 between junction 18 (Avonmouth) and junction 19 (Portishead) in the southbound direction, while northbound traffic was blocked between junction 21 (Weston-super-Mare) and junction 18.

The route reopened just after midnight, according to National Highways, ending a closure that affected both directions of the motorway near Bristol.

The section of road stayed closed long enough to cut off a major stretch of the M5 until after midnight, according to multiple reports. For drivers using that part of the motorway, the practical impact was the loss of a direct route through the Bristol section while police dealt with the incident.

What Were the Traffic Delays and Impact on Motorists?

As reported by The Mirror, drivers have been warned of delays surpassing one hour, with some reports indicating delays of over 65 minutes near Bristol Airport after the M5 was shut between the affected junctions.

Currently, the M5 near Bristol Airport experienced delays surpassing one hour due to a “police incident” that resulted in the motorway being closed in both directions close to Avonmouth.

According to National Highways, the M5 in Somerset closed south between Junction 18 (M49) and Junction 19 due to an incident led by Avon & Somerset Police.

The northbound lanes were also closed from Junction 21 to Junction 18, with southbound traffic currently being redirected and a delay of 60 minutes in both directions reported.

Officials at Bristol Airport urged passengers on departing flights to

“seek alternative routes and allow extra time for their journey”

amid the ongoing incident on the M5. Further delays were noted on the M32 and Newfoundland Way heading into the city centre, with traffic monitoring service Inrix indicating a travel time of 35 minutes into Bristol city centre.

Traffic cameras indicated that northbound congestion extended back to the J17 Cribbs Causeway exit and nearly reached junction 21 at Weston-super-Mare, according to BBC News. Motorists are being advised to steer clear of the M5 due to significant delays nearing the Avonmouth Bridge in the vicinity of Bristol.

What Did Police Say About the Arrest?

As reported by BBC News,

“A man in his thirties was arrested on suspicion of causing a public nuisance,”

police said. The man arrested was in his thirties, according to police, leaving the road situation resolved, but the arrest ties the closure to a police inquiry rather than to a routine traffic hold-up.

Anyone travelling that stretch after the reopening had the motorway back in use, but the case itself now sits with police under the public nuisance allegation. The arrest was on suspicion of causing a public nuisance, police confirmed.

What Is the Public Nuisance Offence Under UK Law?

As explained by the Green and Black Cross guide on laws, public nuisance generally means doing something which creates a risk of serious harm to the public or stops the public from being able to exercise their rights. The public part is important—it can’t just affect an individual or a private group and has to affect the public or a section of it.

According to the UK Government’s report on simplification of criminal law, public nuisance is a common law offence involving environmental danger or loss of amenity or offensive public behaviour. This offence is very old but was brought into statute by the Police Crime Sentencing and Courts Act 2022.

The PCSC Act reduced the maximum penalty from life imprisonment to 10 years or an unlimited fine or both. It is an either-way offence, meaning it can be tried in the Magistrates’ or Crown Court.

How Did National Highways Respond to the Closure?

As reported by BBC News, according to National Highways, this section of the motorway resumed operations shortly after midnight. National Highways also indicated that

“Avon and Somerset Police are conducting investigations at the scene”

during similar incidents.

In a statement during a previous closure, National Highways reported:

“The M5 is closed in both directions, and drivers are urged to find alternative routes”.

A local diversion was currently in effect before the closure, with traffic on the southbound side being released from the back of the queue.

What Were the Effects on Bristol City Centre Traffic?

As reported by The Westminster Pimlico News, M5 traffic disruption continued across Bristol after a police-led incident, and although the motorway had reopened, long delays remained on city routes. Further delays were noted on the M32 and Newfoundland Way heading into the city centre.

The closure resulted in heavy traffic around Bristol, according to ITV News West Country. The highway was presently blocked from junction 19, which serves Portishead, to junction 18 where the M5 intersects with the M49.

Background: Understanding the M5 Closure Development and Public Nuisance Arrest

The M5 motorway closure near Bristol on Sunday night represents a significant traffic disruption incident that escalated from a police-led situation to a criminal arrest.

The development centres on Avon and Somerset Police’s decision to close a major stretch of one of the UK’s primary motorways for more than four hours, affecting both northbound and southbound traffic flows.

The closure began at approximately 20:00 BST on Sunday, blocking the motorway between junction 18 (Avonmouth) and junction 19 (Portishead) southbound, and between junction 21 (Weston-super-Mare) and junction 18 northbound.

This specific section of the M5 is particularly重要 as it serves as a critical transport link connecting Bristol Airport, the city of Bristol, and surrounding Somerset areas.

The arrest of a man in his thirties on suspicion of causing a public nuisance represents a notable development in understanding the nature of the incident.

The public nuisance offence, as defined under UK law, involves doing something which creates a risk of serious harm to the public or stops the public from being able to exercise their rights.

This common law offence was brought into statute by the Police Crime Sentencing and Courts Act 2022, which reduced the maximum penalty from life imprisonment to 10 years or an unlimited fine or both.

The incident connects to broader patterns of M5 closures near Bristol, with multiple police-led incidents occurring in recent months including closures in January 2026, March 2026, and November 2025.

Each of these incidents has resulted in significant traffic disruption, with closures ranging from four to超过12hours in some cases.

National Highways has consistently played a role in managing these closures, confirming reopenings and providing diversion information.

The organisation’s standard response includes urging drivers to find alternative routes and releasing traffic from the back of queues.

Bristol Airport’s response to these closures has been consistent, with officials urging passengers to seek alternative routes and allow extra time for journeys.

The airport’s proximity to the affected M5 section means that closures directly impact passenger travel times and airport accessibility.

Traffic monitoring services such as Inrix have documented the extent of congestion resulting from these closures, with travel times into Bristol city centre reaching 35 minutes during incidents.

Traffic cameras have shown congestion extending back to J17 Cribbs Causeway and nearly reaching junction 21 at Weston-super-Mare.

Prediction: How This Development Can affect Motorists, Bristol Airport Passengers, and Regional Travellers

This development can affect motorists in several significant ways. Drivers using the M5 near Bristol should expect potential delays of over 65 minutes when similar police incidents occur, as reported during this closure.

The arrest indicates that future closures may involve criminal investigations rather than routine traffic incidents, potentially extending closure times as police conduct thorough investigations.

Motorists planning to travel through the Bristol section of the M5 during evening hours should consider alternative routes such as the M49 or local diversion routes that National Highways typically implements.

The pattern of multiple closures near Bristol in recent months suggests that travelers should monitor traffic conditions before departing, particularly during Sunday evenings when this incident occurred.

Bristol Airport passengers face direct impact from this development. Passengers on departing flights should seek alternative routes and allow extra time for their journeys, as officially advised by Bristol Airport officials during the closure.

The airport’s proximity to the affected M5 section between junctions 18 and 19 means that similar closures could delay passenger arrival times by over an hour.

Travelers flying from Bristol Airport should consider arriving at least two hours earlier than standard recommendations when traveling on Sundays or during periods of heightened police activity in the region. Alternative routes to the airport include the M5 via junction 17 Cribbs Causeway or local roads through Bristol city centre, though these may also experience congestion.

Regional travellers connecting to the M5 from Somerset, Devon, and Cornwall should be aware that northbound congestion can extend back to junction 21 at Weston-super-Mare during closures.

This means that travellers from southern Somerset areas may face significant delays even before reaching the closed section.

Business travellers and commuters relying on the M5 for regular transport between Bristol, Somerset, and以外的areas should develop contingency plans for evening travel, particularly on Sundays.

The 20:00 BST start time of this closure suggests that evening travel during weekend periods may carry higher risk of disruption.

The public nuisance arrest indicates that future incidents may involve criminal investigations rather than routine emergencies, potentially extending closure duration.

Travellers should expect closures to last longer when criminal investigations are involved, as police must conduct thorough investigations before reopening the motorway.

Local residents in Avonmouth, Portishead, and Weston-super-Mare should anticipate continued traffic disruption on surrounding roads as diverted traffic seeks alternative routes during any future closures.

The M32 and Newfoundland Way into Bristol city centre have shown significant delays during incidents, affecting local residents’ access to city centre services.
