At least one lane of the M4 eastbound was blocked because of a broken-down vehicle between Junction 17 (Chippenham) and Junction 16 (Swindon West) today, said the Highways Agency at about 1pm.

The M4 has now been reported to be clear. 

Earlier today there was an incident involving a Ford Transit towing a car on a trailer and another vehicle on the M4 westbound, between the same junctions, at about 9.30am today.
