A crash on the A30 is causing long delays at rush hour.
There are reports of very slow traffic in both directions following a collision between the A39 junction at Carland Cross and the Boxheater junction on the B3285 at Zelah.
It is adding to an already difficult community across Cornwall, with traffic also reported to be queuing in Tregolls Road and Highertown in Truro, and past RNAS Culdrose near Helston.
There is a similar situation on the A30 Hayle bypass, heading towards Penzance between the Loggans Moor Roundabout and the St Erth Roundabout, and on the A30 heading towards Penzance between Crowlas and the Newtown Roundabout.
