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 years, several other AB superconductors were found. Niobium-germanium held the record for the highest temperature of 23.2 K from 1973 until the discovery of the cuprate superconductors in 1986. It took time for the method to produce wires from the very brittle A15 phase materials to be established. This method is still complicated. Though some A15 phase materials can withstand higher magnetic field intensity and have higher critical temperatures than the NbZr and NbTi alloys, NbTi is still used for most applications due to easier manufacturing. NbSn is used for some high field applications, for example high-end MRI scanners and
