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 A15 phases The A15 phases (also known as β-W or CrSi structure types) are series of intermetallic compounds with the chemical formula "A""B" (where A is a transition metal and B can be any element) and a specific structure. Many of these compounds have superconductivity at around , which is comparatively high, and remain superconductive in magnetic fields of tens of teslas (hundreds of kilogauss). This kind of superconductivity (Type-II superconductivity) is an important area of study as it has several practical applications. The first time that A15 structure was observed was in 1931 when an electrolytically deposited layer of
