A63 road filling station is on the westbound side, west of the Melton interchange. The Yorkshire Wolds Way crosses at this point. The North Ferriby bypass and North Ferriby – Hessle sections opened in 1961. The former route is partly the B1231 (for Swanland). The road meets the A15 at a grade-separated junction. The former route, before the South Docks Road improvement, followed the current A1105 into Hull. The road continues through the Humber Bridge Country Park, across the Hull-Selby railway, and under the Humber Bridge. The Humber bridge was designed to take some of Hull's traffic southwards, but the vast majority
A15 phases tungsten was examined. Discussion of whether the β–tungsten structure is an allotrope of tungsten or the structure of a tungsten suboxide was long-standing, and even in 1998 articles about the discussion were published. It seems most likely the material is a true allotrope of tungsten. The first inter-metallic compound discovered with typical AB composition was chromium silicide CrSi, discovered in 1933. Several other compounds with A15 structure were discovered in following years. No large interest existed in research on those compounds. This changed with the discovery that vanadium silicide VSi showed superconductivity at around 17 K in 1953. In following
