About this page
This page lists incidents on the A40 as the data sources report them: lane and road closures set by National Highways, what the overhead message signs say ("REPORT OF COLLISION", "STRANDED VEHICLE"), and TomTom's reports with delay times and queue lengths. Reports of the same event are merged, and every line comes from the sources' own facts. Times are UK time. Always follow the signs on the road.
