Grayling focuses on road repairs and the regions with extra Autumn Statement cash to boost output

The transport secretary Chris Grayling has revealed more details on how he will spend his slice of an extra £23bn fund to boost economic output, focusing largely on roads and highway maintenance and on upgrade schemes outside South East England.

He made a statement to Parliament and visited Cambridgeshire to witness the start of the £1.5bn A14 upgrade. He said that of the additional funding announced by the Chancellor last week, £925m will be for highway maintenance for local roads on top of existing funding; £175m to improve "the 50 most dangerous roads," £220 to Highways England to combat congestion, £27m for the Cambridge to Oxford expressway. The rest will be for six local major transport schemes, predominantly road schemes including a Tees Valley east-west link and the Shrewsbury north-west relief road, but also for the renewal of the Sheffield Supertram.

He also announced the outcome of five strategic studies for road schemes, leading to the upgrading of the A66 to provide a quicker link between North Yorkshire and Penrith and enhancing of junctions on the A69 between Newcastle and Hexham; and improvements to the north-west quadrant of the M60. But he said no decisions had been reached following studies on the A1 in the East of England and improving connectivity between Manchester and Sheffield across the Pennines.

The funding for "dangerous roads" would include schemes for the A588 in Lancashire, the A529 in Shropshire and the A18 in Lincolnshire.

And he announced funding to develop business cases for further schemes to boost economic output including extending the Manchester Metrolink to Manchester Airport and a new Tees Crossing and promised to announce local major transport schemes funded from the £1.8 billion Local Growth Fund announced by the Chancellor in the Autumn Statement "in the coming months".
