New signs have been installed on part of the Broadland Northway (NDR) to encourage drivers to slow down.
The signs have been put in place due to an issue with people approaching the airport north roundabout too fast and failing to slow down to negotiate the junction.
Existing signs which were damaged following accidents have also been replaced.
Council bosses hope the new signage will help people to drive at more appropriate speeds when approaching the roundabout from either direction.
Work to install the signs was carried out as part of planned works to repair kerbing and existing signs, and to refresh the while lines around the roundabout.
Its comes as monitoring cameras installed at four locations, Drayton, North Walsham, Wroxham and airport north roundabouts last week to assess traffic issues will be removed tomorrow and the footage will be reviewed in due course.
