A LORRY driver has been arrested on suspicion of dangerous driving after a cyclist was seriously injured in a collision on the A38 this morning.
Police said the incident happened between the Plympton and Lee Mill junctions on the Exeter-bound carriageway of the road at about 10.50am.
Police, paramedics and the air ambulance were called to the crash and the cyclist was treated at the scene before being airlifted to Derriford Hospital with serious injuries.
The roads around Lee Mill and Smithaleigh are said to be 'gridlocked' with three lanes shut.
A spokesman for Devon and Cornwall Police said "The lorry driver, a man aged in his early 40s, was arrested on suspicion of dangerous driving and remains in custody at Charles Cross police Station."
All three lanes Exeter-bound were shut to allow the air ambulance to land.
All lanes of the A38 west-bound remain closed while police and emergency teams are on the scene.
Queues are reportedly tailing back to Marsh Mills roundabout in Plymouth, with some drivers saying they have been stuck in the queue for an hour.
The collision is causing problems for bus services, with Plymouth City Bus reporting delays to services in the area.
A police spokesman said: "We ask drivers to avoid the area if possible, traffic is at a standstill on the A38 and the back lanes around the area are gridlocked."
