Two lanes closed on M1 near Northampton
Two lanes are closed on the M1 northbound between J14 and J15.
The closures are necessary because an HGV has become stationary following a traffic collision.
A Highways England spokesperson said at 11.55am that motorists should expect "delays of at least 30 minutes above normal travel time on approach".
UPDATE: ALL LANES WERE REOPENED BY 12.30PM ALTHOUGH TRAFFIC WAS MOVING SLOWLY
