Drivers are being warned of long delays on the A1 after a devastating collision and lorry fire, with delays potentially being seen until this evening. The A1 in Cambridgeshire remains closed northbound between J17 of the A1(M) (near Peterborough A1139) and the A47 (near Wansford). ### Two heavy goods vehicles were involved in a "serious collision" at around 3am and subsequently caught fire. National Highways confirmed that the closure remains in place to "facilitate vehicle recovery" and collision investigation. ### TRENDING Stories Videos Your Say ### The northbound carriageway remains closed, although the southbound carriageway has since been reopened. Lane two (of two) remains closed to allow emergency services to work safely at the scene and carry out investigations. All traffic caught within the closure has now been released, although motorists are facing lengthy delays. Once recovery of the vehicles and the collision investigation has been completed, the scene will be assessed for any carriageway damage. ### ### ### The lorry fire has caused "substantial road surface damage", according to National Highways, which will require the carriageway to be resurfaced. Plans are being developed to mobilise a resurfacing crew to attend once recovery and the investigation are complete. The transport organisation stated that the initial scene clearance and recovery operation was "complex" and would be protracted. Motorists are being urged to seek alternative routes as the northbound carriageway is not expected to reopen until "later this evening". ### LATEST DEVELOPMENTS * London welcomes new self-driving car trials as Chinese robotaxis hit the road - 'Defining milestone' * DVSA allows Britons to report rulebreakers months after rolling out new driving laws * UK drivers face 'grim' fuel cost hikes as some petrol stations charge over £2 for diesel ### ### ### The Peterborough Volunteer Fire Brigade confirmed its attendance on the A1, posting images of its firefighters battling the blaze.
