The Council is advising that 3D scanning of the First Churchill Barrier will now start on Friday 28 April, when suitable weather conditions are forecast.
For the safety of the engineer carrying out the survey, a convoy vehicle and stop-go signs will be used to control traffic flow and speed.
The road surface will be surveyed in sections. Each section will take a few minutes to complete, and all traffic will be stopped while scanning takes place. Once the engineer finishes scanning a section and is moving the equipment to the next section, traffic will be allowed to flow again under convoy.
Every effort will be made to keep delays to a minimum, but drivers are asked to allow a little extra time for their journeys.
It is expected the scanning will take a couple of days to complete. Weather permitting, work will resume again on Tuesday 2 May.
