# Concrete Spillage Forces Major Closures Following A18 Collision at Schänzli Tunnel

A 57-year-old driver escaped injury after his cement mixer collided with a bridge pier on the A18 near Muttenz, spilling nine cubic meters of wet concrete. The accident triggered significant traffic delays on the A2 as cleaning crews and structural engineers responded to the scene.

## Key takeaways

- A 57-year-old driver crashed a cement mixer into a bridge pier on the A18, resulting in a total loss of the vehicle.
- Nine cubic meters of liquid concrete covered 60 meters of the roadway, requiring extensive cleaning operations.
- The accident caused the closure of the Birsfelden entrance and St. Jakob exit, leading to significant congestion on the A2.
- Structural engineers were required to inspect the bridge pier supporting the A2 motorway following the impact.

## What Happened

A heavy vehicle accident occurred on Monday shortly after noon near the Schänzli Tunnel in Muttenz, Basel-Landschaft. A 57-year-old man driving a cement mixer was entering the A18 toward Delémont when he lost control of the vehicle at a lane merger. The truck collided with a safety barrier and subsequently struck a bridge pier supporting the A2 motorway overpass.

The force of the impact with the pier tore open the mixer unit. Approximately nine cubic meters of liquid concrete spilled across the roadway, coating a 60-meter stretch of the pavement. While the truck was declared a total loss, the driver was able to exit the vehicle without assistance and reported no injuries.

## Key Facts

- The incident involved a 57-year-old male driver who remained uninjured.
- Nine cubic meters of liquid concrete were distributed over 60 meters of the A18.
- The vehicle struck both a roadside safety barrier and a bridge pier.
- The Birsfelden entrance toward Delémont and the St. Jakob exit were closed for recovery and cleaning.
- Structural engineers were dispatched to assess the integrity of the impacted bridge pier.

## Background

The Schänzli Tunnel area serves as a critical junction connecting local traffic from Birsfelden and Muttenz with the broader A2 and A18 motorway networks. The collision occurred at a point where lanes merge before entering the tunnel structure, a site that handles significant regional transit volumes.

## What Happens Next

Local authorities, including the Basel-Landschaft Cantonal Police, have launched an investigation into the cause of the loss of control. Maintenance teams completed the removal of the hardening concrete to prevent permanent road damage, while structural specialists are evaluating whether the collision with the bridge pier necessitates repairs to the A2 overpass infrastructure.
