The Carr Mill pub will reopen on April 12 GREENE King has confirmed that it will reopen three of its managed pubs outdoors in St Helens from Monday, April 12. The Star reported earlier in the week that the Glass Horse on Sherdley Road and The Gerard Arms in Dentons Green has announced they would be opening outside premises. The brewery has confirmed that the Carr Mill pub on the East Lancs will also open on that date. The company will seek to reopen many more of its establishments from May 17 when indoor hospitality is expected to be permitted under the lockdown exit roadmap.
