You sometimes have end around taxiways that are at one end of the runway and can be used when active. But that could be a massive diversion.
I know that Heathrow have multiple fire stations and rendezvous points for emergency services so that fire service can attend even when one runaway is closed to crossing. This could be needed to allow continued operations following a crash. It allows them to accept emergency landings more easily whilst maintaining emergency service to another active runway.
