Waltham Cross Interchange is junction 25 of the M25. It is a grade separated signalised roundabout interchange, sandwiched between the New River Aqueduct and Holmesdale Tunnel.
When constructed, there was a lane drop from three to two lanes for the M25 underneath the junction. In the 2000s the carriageway under the junction was widened to three lanes in each direction. This situation did not last long, as widening to the M25 on either side of the junction was completed in 2015, providing four lanes in each direction, and three through the junction.
Roundabout Capacity Improvements
In 2016, plans were announced by Highways England for a £25-50m capacity improvement scheme at the interchange (source: [https://web.archive.org/web/20160801132634/http://www.highways.gov.uk/roads/road-projects/M25-Junction-25-Improvements Highways England. Two options were proposed;
- Option 1 – Extra lanes on roundabout and widen the A10 southbound approach
- Option 2 – Extra lanes on roundabout, widen the A10 southbound approach and M25 approaches, and provide free-flow left turn from M25 clockwise to A10 north
In June 2017, it was announced that following consultation Option 2 would become the preferred route.
