A public consultation on the future of hospital services in Calderdale and Huddersfield will be launched on March 15.
NHS bosses are proposing to make Halifax’s Calderdale Royal Hospital a centralised emergency centre for the two district under plans to tackle a £280m budget gap.
Huddersfield would lose its A&E under controversial plans which have sparked a backlash from people worried about increased journey times to hospital.
Both towns would also have “urgent care centres” treating less serious ailments.
Calderdale and Greater Huddersfield Clinical Commissioning Groups (CCGs) said the consultation would run from Tuesday, March 15 until midnight on Tuesday, June 21.
A series of public meetings will be held over the 14-week period.
Dr Alan Brook chairman of NHS Calderdale CCG, said: “We are aware of the strength of feeling and passion that people have for health services and we encourage them to be actively involved in the consultation process.”
Calderdale hospital will be expanded from 400 beds to up to 700 if the plans go ahead.
Huddersfield Royal Infirmary, which also currently has 400 beds, would be demolished and replaced with a smaller 120-bed hospital at its Acre Mills site.
