Traffic is particularly heavy on Île-de-France roads this lundi 15 juin 2026. According to the Sytadin barometer, the bouchons exceed 400 kilometers during peak hour, well above the average for a typical Monday morning. Several accidents are worsening the situation, notably on the A13 and the N1104.
At 8:40 a.m., Sytadin logs 427 kilometers of traffic jams across the Île-de-France network. Normally, that figure barely exceeds 250 kilometers at the same time.
We are well above typical levels, making travel to Paris as well as to the provinces considerably more difficult. The Sytadin indicator has been climbing steadily since the early hours of the morning.
On the A13, an accident has occurred in the direction to Paris, between Mantes and Orgeval. Traffic remains heavy between the Mantes exit (D928) and the A13-A14 interchange at Orgeval. Expect about 55 minutes to cover 24 kilometers, compared with 25 minutes under normal conditions.
On the N1104, another crash involving a car and a motorcycle is disrupting traffic heading toward the province, at Compans in Seine-et-Marne (77). These incidents account for part of the slowdowns observed this morning.
Here are the latest network alerts reported by Sytadin on Île-de-France roads:
To monitor live traffic jams, the Sytadin barometer remains the reference in Île-de-France. It continuously tracks the number of kilometers of slow traffic, accidents, and closures across the network.
Before you hit the road, we advise you to check the traffic bulletin, just as you would the Bison Futé forecasts, to tailor your route and departure time. The situation is expected to ease gradually after the morning peak, but caution remains prudent on the main arteries.
