HS2 Updates

26th April 2017

Following the HS2 Act 2017, works started on the new railway, with a large construction site south of Maple Cross that will be used to create the 13km Chiltern tunnel which starts under the M25; and the Colne Valley Viaduct (3.3km long), which starts at a launch over the A412 Denham Way. Full details of the scheme are available here.
