Girton Interchange is a major junction between the A14 (junction 26, formally junction 31), M11 (junction 14), A428 and A1307, north-west of Cambridge. Due to be modified as part of the Ellington-Fen Ditton A14 upgrade.

History

Originally, all that was here was a simple T-junction between the A604 Huntingdon Road and The Avenue, which is the minor road on the north side of the junction heading towards the nearby village of Madingley. In 1977 the A45 Cambridge Northern Bypass opened, followed soon after by the M11 Western Bypass, which both met the newly dualled A604 at this site.

By the early 90's, most of the road numbering in the area had changed. Most of the former main routes through Cambridge had lost their original numbers, with the pre-bypass A45 becoming the A1303, while the A604 between Girton and Fourwentways had become the A1307. The planned A14 promptly took over the A45 route east of Girton and the A604 route north of it, while the A428 was extended east from its previous terminus of the Black Cat Roundabout to take over the former A45 from St Neots to Girton. As such, by the late 90's, only the M11 remained with the same number as it had opened with at the junction.

All the renumbering had changed the traffic flows of course, with major East-West traffic now using the A14 route rather than the former A45 route. With North-South traffic between the M11 and A1 also using the now highly congested stretch between Girton and Huntingdon, the junction was included in plans for an upgrade to the A14 between Ellington and Fen Ditton that would have involved a major rebuilding.

In 2013 the upgrade plan for the junction was scaled back. The only new free-flow link in the latest scheme is a right-turn for the A14(W) through-route, replacing the current 270-degree loop and its hair-raising crossover with the M11(N)-to-A14(E) slip road.

As part of the Huntingdon to Cambridge improvements, two new roundabouts will be constructed on the A1307 local access road, called Girton West Roundabout and Girton East Roundabout respectively1
