"We are extremely sorry for the mistake," said a city spokesman on Thursday.
The bridge was only officially named Helmut Schmidt Bridge on Wednesday and the sign was attached and unveiled that day.
The sign says the year of his birth, 1915, but Helmut Schmidt didn't quite live to be a hundred.
He was born on December 23, 1918.
In the evening, the city was made aware of the error.
The sign had already been taken down in the morning and a new one had already been commissioned.
It is unclear why the "extremely annoying error" occurred.
You look into the matter.
The sign had incorrectly stated 1915 as Schmidt's year of birth.
But the SPD politician was born in 1918.
Helmut-Kohl-Straße was inaugurated together with the Helmut-Schmidt-Bridge.
However, all the data on this sign is correct.
