AN OVERTURNED trailer on the M4 Westbound has been recovered. 

Two lanes were closed between Junction 16 and 17 but have now been reopened. 

The tailbacks had reached six-miles and were causing travel times of up to 90 minutes. 

The congestion had started to create issues for Swindon's roads with areas of Freshbrook and Toothill feeling the impact. 

A motorist caught in the congestion at 5.05pm said: "It's absolutely manic. It's very slow, I've been in this for 45 minutes and it's stop-start. I got on at Junction 16 at 4.20pm and I've not even passed Royal Wootton Bassett yet, there's still 15 miles to go before I reach Chippenham."

Roads should now be returning to normal.
