The mystery of why sets of peculiar road markings have appeared on roads in towns and villages across the region has been solved.
People started asking questions this week after being baffled by the sudden emergence of white squares painted on roads in Essex, Norfolk and Suffolk.
The intriguing symbols, in a Battenberg-like pattern, were reported in Suffolk at Raydon, near Hadleigh, and Gislingham, near Eye; in Essex at Ingatestone, near Brentwood, and Margaretting, near Chelmsford; and near Norwich.
National Grid has confirmed they are related to mobile mapping surveys being carried out to collect data as part of its Norwich to Tilbury pylon scheme.
