Just five months after Ed Koch’s death, a Queens lawmaker is seeking to erase Hizzoner’s name from the Queensboro Bridge.

City Councilman Peter Vallone Jr. says he’s drafting legislation to restore the crossing’s official moniker and to name Manhattan’s Municipal Building after Koch instead.

“Never in a million years would they think to rename the Brooklyn or Manhattan bridges,” Vallone told The Post. “But for some reason, it was OK to slap Queens around.

“I’m not going to rest until it’s rectified, until we get our bridge back.”

The span, built in 1909 to connect Midtown to Long Island City, was renamed the Ed Koch Queensboro Bridge in 2011 to celebrate his 86th birthday.

Back then, Vallone helped Queens residents circulate a petition against Mayor Bloomberg’s proposal. A year later, Vallone unsuccessfully pushed a bill prohibiting the city from naming its landmarks after living people.

Koch once called the renaming one of “the high points in my professional life.” In 2012, he was featured near the bridge in a video for Bloomberg’s State of the City address yelling, “Hey! Welcome to my bridge!”

“My problem is not with Ed Koch,” Vallone said. “My problem is with taking a bridge from the people of Queens.”
