Where was the project located?
The scheme passes through the districts of Nottinghamshire, Peterborough and Lincolnshire.

Why was the scheme needed?
The A1 is a route of national strategic importance, providing an alternative to the M1 for strategic north south movements across the country. The route also forms an important link between the communities along its length and the rest of the country, carrying a mixture of local, long distance and seasonal holiday traffic. Much of the route is of a satisfactory standard but there were localised problems at six roundabouts at: Blyth, Apleyhead, Markham Moor, Gonerby Moor, Colsterworth and Carpenters Lodge in the East Midlands.

The scheme objectives can be summarised as:

  • Reduction of delays - The separation of the A1 and local traffic at the junctions will significantly reduce delays, for both through and local traffic;
  • Reduction of accidents - The removal of the A1 through traffic from the junctions will remove the potential for accidents at the junction by reducing traffic volumes and potentially dangerous crossing movements; and
  • Improvement of Non-Motorised User Safety - The provision of appropriate facilities will allow non-motorised users to negotiate the junction more safely, reducing severance.

What work was carried out?
The A1 Peterborough to Blyth Grade Separated Junction scheme improved 73 mile (117.5km) length the A1 trunk road. The scheme involved the construction of six new two-level junctions, resulting in the removal of all the at-grade at the following locations (from north to south):

  • Blyth (A1/A614);
  • Apleyhead (A1/A614/A57);
  • Markham Moor (A1/A57);
  • Gonerby Moor (A1/B1174);
  • Colsterworth (A1/A151) and the junction of A1/B6403; and
  • Carpenters Lodge (A1/B1081)

Due to the size and complexity of the scheme, it was necessary to construct and complete the scheme in phases to keep disruption to a minimum; the various construction start and completion dates from north to south were:

  • Blyth: junction construction began in September 2006 and completed in May 2008
  • Apleyhead: junction construction began in September 2006 and completed in May 2008
  • Markham Moor: junction construction began in March 2007 and completed in March 2009
  • Gonerby Moor: junction construction began in October 2006 and completed in June 2008
  • Colsterworth: junction construction began in July 2007 and completed in October 2009
  • Carpenters Lodge: junction construction began in July 2007 and completed in November 2008

How did this benefit road users?
The A1 Peterborough to Blyth Grade Separation Junction scheme will remove the bottlenecks on this section of the A1 thereby improving safety, reducing congestion and providing more reliable journeys.

Following scheme completion, we undertake a Post Opening Project Evaluation (POPE) to assess whether the scheme has achieved its anticipated outcomes. The evaluation is generally carried out at one and five years after scheme opening. The results of the POPE allow us to learn lessons and improve future scheme delivery.
