The Wirral edition will provide increased local news coverage for the borough's 320,000 residents while ensuring Wirral readers still receive the best sports, news and features from the rest of Merseyside, say publishers Trinity Mirror.
Two new reporters were recruited to enhance the Echo's Wirral coverage.
The edition will carry changed front and back pages plus two inside editorial pages four days a week. Eight additional pages will be added to the edition on Thursday to deliver increased editorial and advertising and up to 24 pages will be added on Friday.
Echo Editor Alastair Machray said: "The Echo is Merseyside's best-selling newspaper and we've been proud to serve this region for over 130 years.
"But we recognise that Wirral is changing and we need to change with it.
"As a destination for tourists, a base for businesses and a home for families, Wirral is getting better and getting stronger.
"We see this as an opportunity so we're producing this new edition of the Echo to reflect the change.
"Many Wirral residents and advertisers were keen to have their own edition. But we also recognise many others have moved across the water from Liverpool and buy the Echo primarily for news and sport from their home city.”
The Wirral edition is the culmination of months of planning and represents the latest in a series of major developments to the North West's Newspaper of the Year. These include the creation of a new Saturday Extra magazine and investment in a new EchoLive rolling blog on its companion website.
