The Capital of the World is going lower-case.
Federal copy editors are demanding the city change its 250,900 street signs — such as these for Perry Avenue in The Bronx — from the all-caps style used for more than a century to ones that capitalize only the first letters.
Changing BROADWAY to Broadway will save lives, the Federal Highway Administration contends in its updated Manual on Uniform Traffic Control Devices, citing improved readability.
At $110 per sign, it will also cost the state $27.6 million, city officials said.
“We have already started replacing the signs in The Bronx,” city Transportation Commissioner Janette Sadik-Khan told The Post. “We will have 11,000 done by the end of this fiscal year, and the rest finished by 2018.”
