The consultation on the Phase Two route closed at the end of January 2014. A decision on this route is expected before the end of 2014. Under the route that was consulted on, significant works would be required between Crewe and Warrington, involving the widening and four-tracking along 24 km of the route, where there are significant constraints. In addition, Crewe station and the junction would need to be remodelled or an additional grade separated junction from the high speed line to the north of the Crewe tunnel would need to be provided. HS2 Ltd have not looked in detail at these works or the potential associated costs.
