A1 Peterborough - Blyth

Scheme outline

Grade-separation of remaining at-grade junctions on the 74 mile section between the A1(M) at Peterborough and Blyth, closing central reservation gaps and finally removing the remaining six roundabouts which are increasingly unsafe due to traffic levels and speeds. The work breaks down to six smaller schemes:

- Blyth (A614): overbridge, possibly with continuous hard shoulders to connect the Doncaster and Blyth Bypasses. Work scheduled Sept 2006 to Feb 2008, costing �£17.3m. - Apleyhead (A57 and A614): overbridges with A1 beneath, realigned slightly to the east. Work scheduled Sept 2006 to Feb 2008, costing �£15m. - Markham Moor (A57): overbridge, making use of the earthworks provided to the south of the roundabout. Work scheduled Feb 2007 to Autumn 2008, costing �£19m. - Gonerby Moor (B1174): overbridges with A1 beneath. Work scheduled Oct 2006 to Feb 2008, costing �£15m. - Colsterworth (A151/B6403): overbridges with A1 beneath. Work scheduled Spring 2007 to Autumn 2008, costing �£12m. - Carpenter's Lodge (B1081): overbridges with A1 beneath. Work scheduled Spring 2007 to Autumn 2008, costing �£9m.
