Long delays on the A5 Southbound in Milton Keynes due to earlier two accidents have now cleared.
One lane was closed earlier between the junctions for the H5/A509 Portway and the V6 Grafton Street.
MKFM listeners were reporting long delays around both the junctions and on the carriageway.
It is not yet known how many vehicles were involved in the collision.
Heavy traffic was also reported in both directions on the A5 at the A422 Old Stratford Roundabout junction.
