Additional information: The Lower Thames Crossing (LTC) is a new road to better connect Essex and Kent through a tunnel beneath the River Thames. Our purpose is to drive a change in how we deliver - connecting people to jobs and businesses to opportunities, leaving a skills legacy for the local community and construction industry, all whilst restoring nature and drawing a new blueprint for low-carbon construction.

Our ambition is to deliver the UK's greenest road, and to do the right thing for local communities and the environment. We can only achieve this with the support of our supply chain, and it is therefore critical that for any supplier to be successful in winning work on LTC, they must demonstrate commitments to supporting delivery of our ambitions:

• Delivering the works through a 'zero emissions' solution, and not using diesel on site in any plant or machinery.

• Helping to facilitate successful opportunities by providing early careers roles, as well as inspiring young people into construction through delivery of STEM engagement.
