Those country lanes we love to drive down in summer were mostly built back in the 1920s and 1930s.
They were an investment in the future, both as physical infrastructure that opened up the countryside to new markets and as employment for men and their families who would have otherwise starved.
They have lasted much better than most canals and railways, because they are less prescriptive about what can travel on them, or for what purpose, which means they can cope with all kinds of traffic, from milk-cart, to ramblers to country commuters.
They form a network, combining direction and connection with flexibility. They enable autonomy.
Pretty good characteristics to aim for in a business infrastructure too. Expensive to build, but well worth the investment.
