The Flore bypass has been closed in both directions after two lorries were involved in a collision this morning.
AA Traffic News is reporting that two lorries were involved and there has been a fuel spillage on A45 Flore bypass both ways from M1 J16 in Daventry to A5 in Weedon.
The road is expected to remain closed until at least 3.30pm today, with motorists advised to avoid the area, Northamptonshire Police this afternoon said (Thursday).
The £40 million link road, which was built to improve the speed of journeys between Northampton and Daventry and improve access between Daventry and the M1, was opened in November last year.
The link road starts at a new roundabout on the existing A45 between the Dodford and Weedon, to the east of Globe Farm. It then passes to the north of the villages of Weedon, Flore and Upper Heyford before rejoining the A45 at a new roundabout between Upper Heyford and the M1 motorway at junction 16.
East Midlands Ambulance Service said: "We received a call at 7.31am this morning (February 21), to Flore Turn, A45.
"The caller reported an Road Traffic Collion (RTC).
"We sent a paramedic in an ambulance car and a crewed ambulance."
