The Pittsburgh Tribune-Review announced it will be expanding its production and printing a new weekend edition to help fill a news void when the Post-Gazette ceases operation in May. 

Trib Total Media President and CEO Jennifer Bertetto announced Wednesday that the company will begin printing a weekend edition that's focused on the city of Pittsburgh and Allegheny County beginning May 9.

Last week, the Post-Gazette announced it will be publishing its final edition on May 3 and shutting down after 240 years of operation, citing unsustainable operating costs and a recent court ruling in favor of the union that represents newsroom staff. 

Earlier this month, the Pittsburgh City Paper ceased operations after 34 years. In a statement, Block Communications said the decision to shut down the alternative weekly was made for financial reasons. 

Bertetto said Wednesday that the Tribune-Review is committed to ensuring that Pittsburgh has a newspaper of record and shares in the loss of a historic pillar in the Post-Gazette.

The Tribune-Review's new weekend edition will be available at retail locations and newsstands. Home delivery will also be available along with a digital edition accessible electronically. 

"This new publication is powered by the deep, existing roots we already have planted in this region," Bertetto said. 

Bertetto added that the Tribune-Review is "going to show the rest of the media world how the Steel City bands together to protect its stories and create a new, sustainable model for journalism."
