A15 road (England) aircrew were killed), which is now the Elsham Wolds Industrial Estate. The former route of the A15, pre-1978, is now called B1206, and ends at New Holland, where the A15 formerly connected with the Humber Ferry. The £5.6 million Brigg Bypass to Barton-upon-Humber Bypass (up to where the B1218 crosses) section opened in June 1978. The £2 million Barton-upon-Humber Bypass to Humber Bridge (A1077 interchange) section opened in September 1978, although some maps show this being open before the southern section to the M180. When this whole section opened to the GSJ with the A1077 (for South Ferriby) in 1978,
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
