Murphy is recruiting for an Security Advisor to join our team at BMJV (Bouygues Murphy Joint Venture) to work on delivering the UK’s longest road tunnel beneath the River Thames, the exciting Lower Thames Crossing project.

The Lower Thames Crossing (LTC) is one of the UK’s most significant infrastructure projects.  LTC is a new road that will connect Kent and Essex through a tunnel beneath the River Thames and will be the greenest road ever built in the UK - creating six times more green space than road. The reliable new route will almost double road capacity over the river east of London to reduce congestion and give millions of people more choice on where they live, work and spend their valuable time.

We have a diverse programme team on LTC that reflects the communities we work in and fosters an inclusive culture by actively supporting the programme's Purpose, Principles and Cultural Pillars and growing employee networks.
