Five cities in northern England will today outline a £15bn plan to improve road and rail connections in the region.
The One North report will include plans for a new 200kph inter-city rail link, improved road links, and better access to ports and airports.
It has been developed by an alliance of five cities: Leeds, Liverpool, Manchester, Newcastle and Sheffield.
The report will be presented to George Osborne in Manchester later.
In June, the chancellor called for “a northern powerhouse”, saying the cities in the region were individually strong but were “collectively not strong enough”.
The proposed high-speed rail scheme – dubbed HS3 – was priced at up to £7bn.
It is expected that the One North report will detail faster links from east to west in northern England, including improved road and rail connections.
Commenting on the report, Civil Engineering Contractors Association (CECA) chief executive Alasdair Reisner said: “The current growth in the UK economy will only be sustained if all parts of the country are allowed to flourish.
“While London has recovered from the recent downturn, cities around the country are being held back by the quality of their infrastructure.
“CECA believes investment in infrastructure needs to be rebalanced across the country. The construction associated with this will drive growth in the short term, while the resulting improvements to transport infrastructure will help cities outside London to thrive, taking pressure off the capital.”
