The pictures above show the road markings and distinctive red box now in place on the A18 Barnard Avenue at the entry from/exit to the Tesco store and Riverside Surgery.
The intention is to deter motorists from from turning right as they join the A18.
Instead, they must go left towards the roundabout at the top of Atherton Way.
Some drivers ignored the 'no right turn' instruction.
But the new road markings from North Lincolnshire Council seem to have improved things from what we've heard and observed.
And anything that improves road safety is welcome.
