The services are an oddity in that a different route is followed in the morning and evening peak. The morning peak service operate as route 174, departing Withernsea at 0730. It operates via Roos, Burton Pidsea, Elstronwick, Humbleton, Sproatley, Bilton and Holderness Road into Hull. The evening service operates as route 175 leaving Hull at 1740 and operating via Hedon and Preston. However it’s not just a different route out of Hull. The 175 operates via Lelley, not served by the 174, then Humbleton, Elstronwick and Burton Pidsea before serving Tunstall, which also is not served by the 174, and Roos into Withernsea.
For some of the towns and villages, alternative services remain into Hull. Withernsea has the main 75-77 group of services, and these along with the 78-80 also link Hedon into Hull. Humbleton, Sproatley and Bilton are served by the 220 (and off peak 221), while Sproatley, Bilton and Preston are served by the 277. However Elstronwick and Lelley become unserved, while Burton Pidsea, Tunstall and Roos’s only link into Hull will be the Saturday 173. Roos, Burton Pidsea and Humbleton are also served by Pearsons Coaches 76C between Withernsea and Humbleton while Roos is also on the route of EYMS service 129 between Withernsea and Hull.
