There have been long delays on the M4 near Bristol this afternoon (January 17) due to icicles above the carriageway. According to National Highways, contractors were called out with lane closures put in place in both directions at junction 20.
Traffic monitoring site Inrix reported delays of around 45 minutes on the westbound carriageway at one point, although these have dropped down to 25 minutes. It reports that lanes two, three and four remain closed with heavy traffic building.
The tailbacks are running past junction 19 for the M32. This is also affecting traffic coming from Hambrook.
On the southbound side, there were delays of around 35 minutes. Traffic was queuing due to the closure of lanes two and three, although it is reported to be easing.
