The following information is from the book, The Streets of Hebburn - if you can help update or correct it, please let me know, thank you:
BYGATE STREET: Hebburn Colliery. Built c.1900. Demolished 1980s.
This street was entered via Argyle Street, and was parallel with the present Makendon Street, which it shared a back lane with. At the end of Bygate Street, was the Bygate Street Nursery School. Ropery Lane ran at the back of this nursery, in an almost straight line, from the Station Bridge, down to St. Aloysius RC Infant School, then took a 90º left turn down Makendon Street back lane until it met with Argyle Street.
The present double gates of St. Aloysius RC Junior Mixed School, is exactly where Bygate Street was.
In 1850, this was arable land, known as ‘Forth Long Field’; occupied by John Redhead, and leased from landowner Cuthbert Ellison.
