A lorry has overturned on the M1 southbound, at J13 A421 (Bedford / Milton Keynes South).
One lane is closed with traffic monitoring site Inrix classing the crash as “high impact” but reporting that traffic is “coping well”.
It comes after the Bakerloo line was disrupted for most of Monday morning.
Although the Bakerloo line has since cleared up, several other lines are facing delays.
