A street lamp post is sealed by the police on the bridge in southwestern city of Mainz on February 22, 2005, before the visit of the US president George W. Bush. Stores and restaurants in the "red zone", the high-security area centred on Mainz's electoral palace, have been advised to close for the day as part of the biggest security operation in the country's postwar history. To keep all travel options open for the president, four highway sections east of the city will be blocked to traffic. Schools will be shut and many workers will be taking a day off.
