Heavy Transport Crash on A2 Near Kamen Closes Motorway After Mobile Crane Overturns

In the early hours of Tuesday, August 18, 2026, a Schwertransporter — a heavy transport truck — carrying a mobile construction crane overturned on the A2 motorway near Kamen/Bergkamen in North Rhine-Westphalia, Germany. The crash, which police said may have been triggered by a tire blowout, spilled diesel fuel and hydraulic oil across the roadway and forced a full closure in both directions between Kamen/Bergkamen and Lünen-Süd. The 35-year-old driver and his 14-year-old son, who were in the cab, suffered minor injuries.

The incident unfolded shortly before 1:00 a.m. local time on a stretch of the A2 that links the Ruhr area with Hannover to the east and Oberhausen to the west — one of Germany’s busiest freight corridors. Emergency crews from Kamen were on scene within minutes, and authorities warned motorists to take wide detours as recovery work stretched through the morning and into the afternoon.

Editor’s note: This article draws on reporting from WDR, RP Online, Rundblick Unna, and DerWesten, along with statements from the Kamen fire department and Münster police, August 18, 2026. Closure times and recovery estimates may change as work continues.

What happened

According to police and fire officials, the heavy hauler was traveling toward Hannover when the driver lost control near the Kamen/Bergkamen junction.

Detail	Information
Date and time	Tuesday, August 18, 2026, around 00:45–01:00
Location	A2, near Kamen/Bergkamen interchange, Unna district, NRW
Vehicle	Schwertransporter loaded with a mobile crane
Suspected cause	Tire blowout (under investigation)
Outcome	Truck overturned; crane fell onto the roadway and crossed the median barrier
Spill	Diesel and hydraulic oil on both carriageways
Injuries	Driver (35) and son (14) lightly injured; hospitalized for observation

The truck struck the central crash barrier and came to rest across the motorway. Parts of the crane load tipped over the divider onto the opposite carriageway, meaning both directions of traffic were blocked from the outset.

Fire department spokesman Markus Grosse told WDR that roughly 30 firefighters were deployed under a major-incident alert. Crews first secured fire protection, then worked to contain leaking fluids before heavy recovery equipment could be brought in.

Timeline of the response

The sequence described by officials and local outlets:

• ~00:45 — Crash occurs; driver reportedly loses control, possibly after a tire failure.
• ~00:56 — Kamen fire department dispatched with a “heavy transport overturned” alert.
• Early morning — Both A2 directions closed; binding agents spread to soak up fuel and oil.
• Morning — Environmental teams dig out contaminated verges; an oil barrier is placed on the nearby Seseke river to block runoff.
• Mid-morning onward — Specialized recovery firm begins lifting the overturned truck and crane; police accident-reconstruction team documents the scene.

Authorities initially estimated that recovery alone could run until late morning, with the full motorway closure potentially lasting until late evening on August 18 as cleaning and inspection work continued.

Injuries and those on board

Police said the driver is Polish and was traveling with his teenage son as a passenger. Both sustained minor injuries and were taken to hospital for observation, according to the Kamen fire service.

No other vehicles were reported to have been struck, and there were no additional casualties as of the first official updates. Given the size of the load and the hour, traffic volumes were lower than during daylight — a factor officials noted may have limited the scale of harm.

Environmental measures

The spill posed an immediate risk to the road surface and nearby waterways.

Fire crews spread absorbent binding material across affected lanes to stop diesel and hydraulic fluid from seeping into the ground. Grosse told WDR that because the Seseke river flows close to the crash site, responders set up an oil containment boom downstream to prevent fuel from entering the watercourse.

Police said green verges along the motorway would also need to be excavated as part of decontamination before the carriageway could safely reopen. That step added time to an already complex recovery operation involving an oversized load.

Motorway closure and traffic impact

The A2 was shut completely between Kamen/Bergkamen and Lünen-Süd in both directions — affecting routes toward Dortmund, Hannover, and the wider Ruhr network.

Direction	Status (as of morning reports)
Toward Hannover	Full closure at crash site
Toward Oberhausen	Full closure; crane debris on carriageway
Detours	Police urged drivers to avoid the area and use alternate routes

The A2 is a primary artery for long-distance freight, including the very heavy transport sector the crashed vehicle belonged to. Morning rush-hour diversions rippled across connecting roads in the Unna and Dortmund areas, with traffic apps and regional broadcasters issuing repeated alerts throughout August 18.

Investigation

A specialized traffic accident documentation team from Münster police headquarters was sent to record the scene using advanced surveying equipment. Investigators will examine tire condition, load securing, vehicle maintenance records, and whether the crane’s weight distribution played any role.

Police have not confirmed a definitive cause. The tire blowout theory remains the leading early explanation cited in official statements, but a full report is expected to take days or weeks.

Discussion

1. Should heavy Schwertransport moves be restricted to certain hours on major autobahns like the A2?

Oversized loads already require permits and escorts, yet this crash shut a key corridor at night with a spill that took hours to contain. Would tighter time windows reduce risk — or simply push dangerous moves onto smaller roads?

2. When a motorway closure runs from midnight into the evening, who should bear the cost of delays — and how do regions plan for that?

Commuters, hauliers, and emergency services all reroute around a single incident. If you rely on the A2 for work or freight, how much disruption is acceptable before infrastructure or recovery capacity needs to change?
