The sequence of events and consequences on the A13
Shortly after 7:30 on Monday, October 5, 2026, the St. Gallen Emergency and Intervention Coordination Center received a report of an accident on the A13 motorway. A 21-year-old man was traveling in his car with a 19-year-old female passenger in the overtaking lane, heading from Sargans toward St. Margrethen.
Near Widnau, the driver lost control of the vehicle. The car then ended up on the emergency lane and struck the guardrail and an emergency call box with its front end. The impact pushed the vehicle back onto the roadway, where the car spun. Immediately afterward, the rear struck the guardrail again. The vehicle finally came to a stop at an angle on the emergency lane.
The driver and passenger were unharmed. The stated damage to the car and the motorway infrastructure amounts to approximately CHF 120'000 in total. The report therefore attributes both the vehicle damage and the damage to the A13 structures to the same incident.
To allow the accident to be recorded and clearing work to be carried out, the right lane was temporarily closed. It was reopened after approximately two hours. A queue formed during the morning commuter traffic, causing the resulting disruptions to traffic.
For anyone who needed to travel on the A13 during the indicated time period, the key point is therefore the combination of Widnau, the Sargans–St. Margrethen direction, and the temporary closure of the right lane. The note also specifies the operational outcome: the lane became available again after approximately two hours, while the effects on morning traffic resulted in queues and slowdowns. Anyone planning a journey can supplement this information by consulting the mezzi pubblici, without interpreting the incident as a permanent closure.
Operational details
Practical impact on mobility
The critical morning window
The most useful element for those traveling is not only the dynamics of the collision, but the operational sequence that affected the roadway. The report came in shortly after 7:30; the right lane was closed for recording the accident and clearing the area; after about two hours the same lane was reopened. In the meantime, morning commuter traffic experienced a tailback and disruption to traffic.
| Reference | Operational information |
|---|---|
| Time | Shortly after 7:30 |
| Section | A13, near Widnau |
| Direction indicated | From Sargans toward St. Margrethen |
| Restriction | Temporary closure of the right lane |
| Developments | Reopened after approximately two hours; tailback in commuter traffic |
The table separates the data needed to identify the incident from the description of what happened. For a trip in the indicated direction, Widnau is the geographic reference to associate with the morning time. In a similar scenario, the documented effect for people on the road may also concern the tailback caused by the operations, not just the site of the impact.
The duration of approximately two hours refers to the communicated closure for recording the accident and clearing work. It should not be read as an abstract measure: it indicates the time after which the right lane was made available again in the incident of October 5. The text also reports the formation of a tailback and the resulting obstacles to traffic in morning commuter traffic.
For those considering a different way of traveling, the report may be complemented by consulting the mezzi pubblici. This indication remains separate from the accident data: the source describes the section, the lane affected, the operations and the effects on traffic, without turning these elements into a general forecast for every trip on the A13.

Five checks before setting out
To turn the notice into a practical check, it is advisable to follow a fixed order. The information in the communication makes it possible to verify whether one's journey matches the incident by date, location, direction, and time window, without adding details that are not present.
1. Date: compare Monday, October 5, 2026 with the day of the journey. 2. Time: check the reference to shortly after 7:30. 3. Location: check the passage on the A13 near Widnau. 4. Direction: compare the route with the one from Sargans toward St. Margrethen. 5. Traffic conditions: take into account the temporary closure of the right lane, arranged for recording the accident and clearance work, and the indication that it reopened after about two hours.
The sequence should be read as a whole, not one piece of information at a time. A reference to the A13 alone is not enough to automatically link every slowdown to this incident; the communication also identifies Widnau, the Sargans–St. Margrethen direction, and the time of the report. Likewise, the two-hour figure describes the reported operation: it does not replace checking the situation concerning the journey being planned.
It is useful to distinguish the vehicle's movements from the management of the carriageway. The car ended up on the emergency lane, while the closure mentioned concerned the right lane. This distinction helps to read the notice correctly without confusing the point where the vehicle stopped with the lane affected by the temporary restriction.
Another operational factor is the effect on traffic: during the morning commute, a queue formed, causing disruption to traffic. For those who need to decide how to travel, this is the information to consider alongside the geographical and time references, without deriving from the source any detours or individual travel times that are not indicated.
To complement this check with an alternative travel option, consult mezzi pubblici.
