Drivers have been warned that loose concrete has led to the closure of a major Southampton motorway. 

One lane of the northbound carriageway of the M271 has been closed from Redbridge Roundabout in Southampton. 

It follows a routine inspection that led to the discovery of a loose section of concrete within the carriageway. 

National Highways contractors are now en route to carry out permanent repairs this evening. 

The road was closed earlier today. 

A full overnight closure will begin at 8pm on the northbound carriageway with diversions set to be put in place. 

A spokesperson said: "Road users are advised to follow the signed diversion from Redbridge roundabout, to join the A35 Totton Bypass, A35 Spicers Hill, A326, to rejoin the M27 at junction 2.
