Waterlooville is one of the largest urban areas in the UK with no rail access and is still expanding, with a mixed-use housing demand of 9000 properties by 2036. This is a common situation around the UK and poorly planned housing has led to higher levels of congestion and pollution. Our project aims to prevent this occurring in Waterlooville, by applying an innovative rail-based infrastructure-first approach, combining sustainable transport initiatives with future housing developments, to improve integration and benefit local communities and system users.

The project centrepiece is Waterlooville interchange, where rail, bus, cycle and walking routes seamlessly connect in one location. A shared space roundabout provides a focal point to the development and contains two natural-form, parametrically designed, timber canopies connected via an underground passage. The structures house station facilities, whilst also providing dedicated spaces for the community. Cycle lanes and footpaths are integrated with the interchange, connecting new housing with existing residential areas, while buses offer quick connections to the centres of Waterlooville and Havant.

Our 9.2km rail alignment proposal offers direct connections to London and Portsmouth, whilst also offering much needed capacity relief to Havant station, which suffers due to local speed restrictions and level crossings. The route requires several sizeable structures, including a 500m long, 14m diameter tunnel and 28.7m span motorway overbridge. Finite Element Analysis software has been heavily utilised to analyse geotechnical elements, while pre-stressed concrete design is used throughout to ensure structural and material efficiency. A full Cost-Benefit Analysis has been conducted and provided a Benefit-Cost Ratio of 1.49 and payback period of 22.55 years.
