Incident at York Hospital

Please be aware that the internal access road to the Blue Badge car park at the front of York Hospital is temporarily closed following a road traffic incident. As a result, drop-off and collection at the main entrance, along with access to Blue Badge parking in that area, is currently unavailable. Pedestrian access is unaffected.

Access to all other areas of the hospital site remains open, including the multi-storey car park, where disabled parking is available.

We’re asking patients and visitors to plan ahead, as traffic flow into the site is busier than usual. Thank you for your patience and understanding.
