The speed limit on a West Norfolk road has been reduced from 60mph to 50mph in two locations on the A149.
From around Monday, weather permitting, work is set to begin to install new signage between Babingley and the Dersingham roundabout, and between Snettisham and Heacham.
Minor delays are expected while the work is carried out. However, the road will remain open at all times.
The £10,000 project, carried out by Norfolk County Council’s Community and Environmental Services Department and its contractors, is set to last two weeks.
