A1 Peterborough - Blyth
You are here: Home - Futures - 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): underpass, 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): underpass, 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.

Progress
- December 2004
- A1/A57 Apleyhead junction is approved, with draft orders published.
- March 2005
- Colsterworth, Gonerby Moor and Markham Moor junctions are all approved.
- March 2006
- Public inquiry is now taking place for Colsterworth Roundabout.
- May 2006
- Site clearance work has started at Blyth and Apleyhead roundabouts (J34 and at A57/B6420). It is not yet clear whether this is the actual start of work or simply some early clearance.
- November 2006
- Work has now started at three sites, with a contractor's village at Gonerby Moor and substantial work at the two most northerly sites. Signs are up warning of delays until November 2007 at some sites and January 2008 at others.
- January 2007
- Work continues, with a start of work at Markham Moor due in February.
- March 2007
- Trees have been cleared at Markham Moor. Apparently consideration is being given to another flyover close by, at Jockey Lane near Elkesley, which would allow the removal of the 50mph limit through the village.
- September 2007
- The Gonerby Moor overbridge is now fully built and stands in a field adjacent to the current A1. Work is now starting on the roads around the rest of the junction.
- November 2007
- At Appleyhead, the southbound A1 is now using the new underpass. Northbound traffic remains on the old roundabout. The overbridge at Blyth is now in place and soon to be in use. Markham Moor now has a bridge in place too, and works in building it revealed the original smaller roundabout inside the existing large one.
- January 2008
- Appleyhead junction is now almost complete apart from landscaping work and minor details on the roundabout, with A1 traffic using the underpass. Carriageway work is well underway at Blyth.
- March 2008
- At Gonerby Moor, the northbound carriageway through the junction is complete, with A1 traffic now using it in a contraflow. At Colsterworth, the new overpass is under construction, with bridge piers completed and the pre-fabricated bridge deck lying next to the road.
- May 2008
- Gonerby Moor and Blyth junctions are now fully open to traffic. Work has started at Carpenter's Lodge.
