The San Diego Union-Tribune is leaving Mission Valley and will be returning to downtown San Diego in May after 43 years.

The newspaper signed a 15-year lease on four floors at 600 B Street, a 24-story building owned by Lincoln Property Company, the Dallas-based developer announced Thursday.

Approximately 350 reporters, editors, designers and other staff will relocate.

The moves comes after the newspaper, now owned by Tribune Publishing of Chicago, transferred printing operations to its parent company’s facilities at The Los Angeles Times.

“We feel like downtown is the right place for us to be, and that 600 B Street will put us in the center of the action,” said Russ Newton, president and CEO of the newspaper.

“We’re proud to be at the forefront of delivering San Diegans the important news of the day, and we look forward to a seamless transition to our new home in the heart of America’s Finest City.”

In 1973 the newspaper moved from offices at 919 2nd Street downtown to a newly constructed building in Mission Valley.
