CNN — (CNN) -- X marks the spot-- again.
The X sign has returned at the approximate location in Dallas where President John F. Kennedy was assassinated 50 years ago.
The mark disappeared earlier this month when the city repaved the road before the anniversary of Kennedy's death Friday.
City officials did not directly address the disappearance of the unofficial marker at Dealey Plaza
In a statement, city spokesman Frank Librio said the work was done to "level out the streets and remove any trip hazards."
"With thousands visiting the area this week, we think that is prudent," he said.
The X had been a popular photo spot despite its location in a busy traffic lane.
Robert Groden, an author and Kennedy assassination conspiracy theorist, said last week that he first painted the X years ago.
But as seen in footage of that Dallas thoroughfare, the X was back Tuesday.
What's not known is who put it there.
