Thursday morning, May 26, saw heavy congestion build during morning rush hour on the M4 eastbound carriageway around Swansea. At their worst, queues stretched from Junction 44 all the way to Junction 48 (Hendy / Llanelli and Forestfach), with a travel time of up to 45 minutes.

Emergency repairs from around 6am at Junction 45 A4067 (Ynysforgan) were initially to blame for the congestion, as one lane was closed to allow for this to take place, according to traffic monitoring service Inrix. But these delays were compounded by a one-vehicle road traffic collision that saw a car land on its roof. The incident happened between Junction 45 and Junction 44 Peniel Green Road (Llansamlet).
One lane was closed following the crash to assist with recovery as traffic officers attended the scene. Cameras showed heavy traffic in the area, with one motorist reporting that congestion was also backing down the hill from the Penllergaer turn off around Junction 47, all the way through to Pontlliw.
