High Speed Two (HS2), the company responsible for the development of high speed rail network in the UK, has released the outline concept for the proposed Colne Valley viaduct.

The viaduct is slated to be one of the most important structures of the HS2 phase I route between London and Birmingham.

The Colne Valley viaduct concepts have been developed by a team of architects, designers and experts and will help devise the final structure’s design, as well as form the basis for discussions with local communities.

Knight Architects developed the concept in collaboration with Atkins and in consultation with the Colne Valley Regional Park Panel and the HS2 Independent Design Panel, which comprises a number of architects, designers and experts.

“The Colne Valley Regional Park Panel looks forward to further engagement with HS2 and Align over the actual viaduct design.”

The concept document also explores the introduction of transparent noise-reduction barriers and other additional elements along the network.

Additional design work and technical development on the concept document is set to be carried out by Align, the civil engineering contractor for HS2 between the Colne Valley viaduct and the northern portal of the Chilterns Tunnel.

Colne Valley Regional Park Panel chair Jim Barclay said: “The construction of the Colne Valley HS2 viaduct will have a significant impact on the Colne Valley area.

“The Colne Valley Panel, which is drawn from local stakeholders, is very pleased to have been consulted, and through a series of workshops, panel members have been able to understand the design principles for the viaduct.

“The Colne Valley Regional Park Panel looks forward to further engagement with HS2 and Align over the actual viaduct design.”

Align will be responsible for developing the final design of the viaduct in accordance with technical specifications and within the agreed budget.

The company is expected to engage with the local communities to devise the final design of the viaduct later this year.
