A carriageway defect has caused 10 miles of slow moving traffic on the M5.

One lane is closed on the M5 northbound in Somerset between J25 near Taunton and J24.

The lane is likely to remain closed for some time and repair works may also require a second lane closure.

The J25 northbound entry slip is also closed.

Drivers are advised to allow extra time for their journey, and consider alternative routes if travelling in the area this afternoon.
