Where it stands, September 2026
Part open, part in planning. The Cambridge end — Adams Road, Grange Road, Coton village — is finished. The rural 5 km from Coton through Hardwick to Comberton Village College, the largest new off-road route left in the whole programme, is in the planning application. The review's assumed grade-separated Long Road crossing has become a surface parallel crossing; the review had argued that at peak times 'a safe crossing is important' and that a concrete box could be installed relatively quickly.

|---|---|---|---|---|
| Widen and upgrade the path and ramps from the edge of Coton to the M11 bridge | Upgrade | 400 m | In design or planning | In the planning application submitted in 2026. |

| Replace the Bin Brook bridge on Burrell's Walk with a wider one | New structure | new bridge | In design or planning | Still in the scheme, unbuilt. |
| Safe crossing of Long Road between Coton and Comberton — assumed to be a new underpass | New structure | underpass | Delivered differently | The 2016 report assumed a grade-separated crossing, noting a concrete box could be installed quickly. The scheme now proposes a surface parallel crossing. |
