Traffic is still at a standstill on the A14, five hours after a serious accident.
Motorists heading out of the county during rush hour are being advised to totally avoid the area.
A van and a lorry were involved in a crash at about 12.45pm today (Friday, September 19) on the eastbound carriageway between junction one at Catthorpe and junction two at Kelmarsh. The lorry overturned on to the grass verge.
Emergency services are still on the scene and the Highways Agency have said it could be 9pm before the road is reopened.
The eastbound carriageway is totally shut between junction one at Catthorpe and junction two but tailbacks are now clear.
The westbound carriageway is also at a standstill for around 10 miles due to passing motorists trying to get a glimpse of the accident.
Traffic on the M6 is backed up because of the congestion.
A diversion will be in place but traffic is expected to be heavy in the area during the evening.
Police are also blocking traffic from leaving the M1 at junction 19 where there are roadworks so the problem is not exacerbated.
There is no news on the injuries sustained by the motorists involved in the incident although it is not believed there are any fatalities.
