Keith Bowers is a Director at COWI who has specialised in major underground transport projects. He is currently assigned to the Lower Thames Crossing as the Tunnels and Systems Director accountable for development and delivery of the main crossing tunnels. These are 4km long twin highway tunnels forming a key part of the proposed Highways England scheme to provide a new road connection between Kent and Essex. This will be the UK's largest highway tunnel and will involve the use of some of the world's largest ever tunnel boring machines. 

Keith was previously Head of Profession for Civil Engineering and Built Environment within the Transport for London (TfL) Engineering Directorate. At TfL he was involved in delivery of numerous infrastructure schemes and, in particular, tunnelling projects for London Underground, Crossrail and on the highway network at Silvertown.

In his earlier career Keith worked on the delivery of the High Speed 1 tunnels and Thameslink Tunnels as part of the Channel Tunnel Rail Link project.  Prior to that he was involved in ground engineering applied research and development at the UK's Transport Research Laboratory (TRL).

Keith is a Fellow of the Royal Academy of Engineering and also of the ICE, IMMM and Geological Society. He was awarded a PhD for work on the early application of sprayed concrete tunnelling methods to soft ground tunnelling in the UK.
