Slip road that joins is dangerous and needs more markings

Reported via desktop in the Road markings (NH) category anonymously at 23:12, Sat 26 February 2022

Sent to National Highways less than a minute later. FixMyStreet ref: 3346856.

I drive this everyday. When cars come from the postwick junction slip road to join the A47 Westbound, cars merge too quickly and try to join A47 immediately at the end of hatched area. It would be safer if the slip had the left hand lane lined off, to force them to go more towards the end of the slip. This would give time for the right hand land to join first. Maybe hatch between the two to force left hand lane down to end more. The fact that both lanes trying to merge and then join A47 with A47 traffic coming round from bend makes it a recipe for disaster. Have seen so many near misses since Broadland Northway opened.

  • Thank you for contacting National Highways regarding the road layout from the Postwick Junction slip road joining the A47 Westbound. We appreciate you bringing this to our attention.

    The local safety inspector has explained that as vehicles already using the carriageway have the right of way, this would be down to drivers' judgement on the main carriageway on how to position when approaching the slip to give vehicles on the slip road the space they need. There are currently no plans for the left hand lane to be lined off as this could cause further confusion and safety issues, however we have passed your concerns onto our Safety Team for further review. We are not aware of any road traffic collisions in the area caused by the layout of the slip road.

    Finally, please note that Broadland Northway is the responsibility of the local authority, not National Highways. If you have any further concerns about this particular area, details for local authorities can be found by using the search facility at:
