The first Road Investment Strategy (RIS), published in 2014, committed to examining the case for improvements to the A1 between the M25 and Peterborough. Following an initial study of the whole stretch, work focused on the sections between junctions 10 (Stotfold) and 14 (Alconbury), where the challenges on the route are most acute.
The findings have shown that improvements, including some new alignment, would offer poor value for money. However, as recognised in the second RIS, published in March 2020, substantial plans for future local growth could change that assessment. Therefore, we expect there will be opportunities to re-examine the case for potential improvements along this section, particularly as proposals for the Oxford to Cambridge Arc, including East West Rail, develop.
