Lord Adonis, chairman of the National Infrastructure Commission, has laid out the top 12 immediate infrastructure priorities on which ministers need to make "rapid progress" in the next year.
He has called on the government to press ahead with key infrastructure decisions, spanning London airport expansion to Eastern crossings of the River Thames, and set out timings when certain developments need to happen for them.
“Britain’s historic weakness has been to underinvest in infrastructure, and to adopt a stop:go approach even where decisions are taken in principle," he said. "Nothing symbolises this more than the long-running saga of Heathrow airport. A third runway was agreed in principle 14 years ago but there has still not been a firm decision to proceed."
The NIC is an independent body providing the government with expert advice on major infrastructure projects.
The top 12 time-sensitive infrastructure priorities:
1. Heathrow third runway
A Commons vote on any finalised national policy statement no later than May 2018; a government response to the consultation on UK airspace published no later than October 2017; a timetable for agreeing an updated national aviation strategy published no later than September 2017.
2. High Speed 2
Introduce the hybrid bill for phase 2a (Birmingham to Crewe) of HS2 and publish the finalised route for Phase 2b (Crewe to Manchester and Birmingham to Leeds), including connections with HS3, and let the major work contracts for the project, by the end of July 2017.
3. High Speed 3 linking the major northern cities
Publish by the end of 2017 a single integrated plan for the first phase of High Speed 3, incorporating proposals for electrifying and upgrading the trans-Pennine (Manchester to Leeds) rail route, plans for the northern sections of HS2, and plans for the redevelopment of Manchester Piccadilly station.
4. Crossrail 2
By the end of 2017 publish a plan, agreed with the mayor of London, for the funding and phased construction of Crossrail 2, and for securing the necessary parliamentary consent.
5. Eastern crossings of the River Thames
Take a decision on planning permission for the Silvertown Tunnel by end of October 2017; announce a financing strategy for the new Lower Thames Crossing and begin environmental impact process, no later than September 2017; agree a policy with the mayor for the next road crossing of the Thames by the end of 2017.
6. Flexible power systems
The government should publish plan for smart energy systems no later than September 2017.

11. 5G mobile
