The new name would be Columbia Way.
On Feb. 2, 2003, space shuttle Columbia broke up as it was reentering the Earth's atmosphere.
Key parts used in the shuttle Columbia and other shuttles were built in Downey.
The Columbia Memorial Space Science Learning Center is on the street officials are looking to rename.
They say they want the street name to reflect the memory of the fateful Columbia mission and the seven men and women who lost their lives in the accident.
The city estimates it will cost $500 per intersection to replace the street signs. That could total up to be as much as $3,500, depending on how long of a stretch of Clark Avenue will be renamed.
