The Government will today raise the amount it expects to be invested in infrastructure projects in the UK from £309 billion last year to more than £375 billion.
Almost 300 of the 646 projects and programmes are already under construction.
Chief secretary to the Treasury Danny Alexander is expected to announce:
- The building of the UK's first toll road in a decade is to be scrapped. The A14 between Cambridge and Huntingdon will not introduce a fee for use after the improvement scheme, due to start in 2016, is completed.
- The railway station at Gatwick Airport will receive £50 million for redevelopment.
- A Government guarantee could support finance for the development of a new nuclear power station at Wylfa on Anglesey.
- The tube's Northern Line £1 billion extension to Battersea in south west London will be guaranteed.
- Improvements to the A50 around Uttoxeter in Staffordshire will start no later than 2015/16.
- A £10 million competitive fund to open in early 2014 to test ways to deliver superfast broadband to remote areas of the UK.
