How much does uk motorway cost to build per mile on average in £?

The Highways Agency estimated cost of motorway is £30m a mile on average.

In 2011, BBC reported that an M74 extension opened in Glasgow at a cost of £692m, which works out at £138.4m per mile or £78,000 a yard (£86,500 a metre). It was then the second most expensive road per mile in the UK - after Limehouse Link, in London's Docklands.

You can see the transparency data for the cost of maintaining the Highways Agency’s motorway and A road network per lane mile at GOV.UK.

Of interest, smart motorway uses technology to actively manage the flow of traffic. The technology is controlled from a regional traffic control centre.

Smart motorways increase the capacity of the road, without the expense and hassle of widening the road, by either temporarily or permanently opening the hard shoulder to traffic. See GOV.UK's quick tips on how to drive safely and legally on England's smart motorways.
