Suzanne Moroney, Institution of Civil Engineers (ICE) London Director said:
"We welcome the Commission's conclusion that Crossrail 2 will help to deliver the much improved capacity and connectivity the capital will need, generate thousands of new homes and should be a priority.
"The Commission is also right to recommend that funds to enable the rail link are released now. If we are to tackle the future challenges of population growth and climate change, and retain London's position as a leading global city, we must plan and mobilise the finance and skills for key infrastructure projects like this now.
"It is the Commission's role to identify our long term infrastructure needs, and recommend how they can best be met. Its recommendation for the capital has been set out, and we now await a positive response from the Chancellor, so the business case revision can progress swiftly and the hybrid Bill is submitted in Parliament as soon as possible."
