Original route Prior to the opening of the M1, the A50 route was one of two main routes from London to the north-west via Leicester, until it was replaced during the 19th century by what has become the
A6. A third route between London and Leicester was via the
A5 to
Old Stratford,
A508 to
Market Harborough and thence the A6. That route and the A50 route both passed through
Northampton which was a significant calling point on many coaching routes until the arrival of the
railways. Until the M1 opened, the A50 used to terminate at
Hockliffe in
Bedfordshire at a junction with the
A5. When the
M1 motorway opened alongside the old route south of Northampton it was down-classified as: • B526 between Northampton and the
Newport Pagnell bypass. •
A509 between the Newport Pagnell bypass and Junction 14 of the M1. •
A5130 between Junction 14 and
Woburn •
A4012 between Woburn and Hockcliffe. From that point until the 1990s the southern point of the A50 was at a junction with the A508 in
Kingsthorpe, Northampton. In the 1990s, with the opening of the
A14 and to discourage traffic from using the road between Leicester and Northampton, the old route was re-designated as A5199 between Leicester and Northampton. At the same time the A50 became the
A511 north of Leicester, between
Burton upon Trent and
Ashby-de-la-Zouch to Leicester when the dual carriageway section bypassing Derby was completed.
Modern route Part of the route mirrored the plans for the original
M64 motorway, with three lanes in some sections – notably between
Kegworth and the A6 near Derby. The new A50 route was opened in stages between March 1985 and 1999, with using various temporary designations: • 1985: £16million
Blythe Bridge –
Uttoxeter section from the north-west. • 1992: £2.6M
Etwall bypass, opened as the
A516. • 1995: £30.4M
Hatton,
Hilton and
Foston bypass, opened by
John Watts as the A564. • 1997 (June): £52M section 1 of Blythe Bridge – Queensway. • 1997 (September): the £109.5M Derby Southern Bypass (opened by
Helene Hayman, Baroness Hayman, Minister for Roads at the DETR), as the A564. • 1997 (September): The A6 Derby Spur. • 1997 (November): the £21M section 2 of Blythe Bridge – Queensway. • 1998: £20.6M
Doveridge Bypass as the A564. • 1999: the delayed A50/M1 junction 24a improvements. On completion, the Southern Derby Bypass was re-designated as the A50, being maintained privately by Connect A50 Ltd. Much of this new section of road is made of
concrete. ==Junction list==
