The government will use the savings generated over the comprehensive spending review 2010 period to fund £6.3 billion of additional infrastructure spending.
This includes £1.3bn that was announced earlier in the autumn.
Alongside this, around £1bn of new private sector investment in regulated industries will be supported by government guarantee.
The government is also announcing commitments to £5bn of capital projects in the next spending review period, as part of the National Infrastructure Plan, and is working with UK pension funds to unlock an additional £20bn of investment in UK infrastructure.
However, it is not clear when that £20bn could hit the ground and how much of this will be used to finance new infrastructure.
In total, the autumn statement supports around £30bn of new capital investment.
