Route Alignment

The project consists of 3 sections:

The Interim Link 

This creates a temporary link for the first phase of the project unlocking housing at Langarth Phases 1 and 2. This section will include a new ghost island junction on the A390. As well as the new A390 junction the Interim Link project consists of 100m single carriageway (6.25m) with a 3m shared foot/cycleway. The section will have a 30mph design speed, but will be calmed to 20mph with features.

West Langarth Junction

The West Langarth Junction connects the A390 to the western end of the NAR which will be constructed as part of the Interim Link. Options for the new junction are still being discussed that will reduce traffic speeds from 60mph to 40mph to 20 mph.

NAR East and remainder of the route

The  NAR East and remainder of the route extends from the east end of the interim link to Treliske Hospital. It will be a 2.4 km section which will be 6m wide with parking bays and footways and cycleways. This section has a 30mph design speed and is calmed to 20mph with features.

NAR Funding

Funding of £47m from the government's Housing and Infrastructure Fund (HIF) was confirmed in June 2019. This is to build the NAR and bring forward the development of new homes .
