SIGNS placed by bridges to help deter people from hurling objects on to the A14 and A12 have been hailed a success.
More than 30 signs were put up on the roads last week following a series of incidents in which items have been thrown from road bridges.
They bear the message ‘Spot Anything Suspicious? Call 999’.
They also have a bridge reference number, which motorists can quote to police.
Extra patrols have also been made around bridges on key routes. An investigation has been launched to catch those responsible for the previous incidents.
A spokesman for Suffolk Police said the signs had acted as a useful deterrent.
He said: “The signs that have been placed around the county have raised awareness of incidents of objects being thrown from bridges. They have generated some calls into our control room but thankfully since the signs placement we have not had any further incidents of this nature.”
