Stagecoach in Hull have produced a leaflet detailing changes to service 20 between Hull, Kingswood, North Bransholme and Wawne from Monday 4th April. See this blog post
To clarify some points, Bodmin Road is no longer served, neither is Kingswood Leisure Park apart from evenings and Sundays. Along with this services will no longer operate via the City Centre Loop in Hull inbound. This helps makes the service quicker and more direct, and contributes towards saving one bus. Passengers between Bodmin Road and Beverley Road can change at North Point Shopping Centre to make their journeys.
With regards to Wawne, Stagecoach explain that East Riding of Yorkshire Council only require an hourly Monday to Saturday service to Wawne, which Stagecoach go beyond at peak times, and in the early morning, evenings and Sundays when no service is required, but Stagecoach will provide a limited service. Still a good service level for Wawne, and Stagecoach aren't providing the bare minimum service level which is to be comended.
