A week of infrastructure, of scientists and design
The opening of the world’s longest tunnel, for a smart new railway line.
The Gotthard Base Tunnel is 57 kilometres from end to end
Across and under Switzerland via straights and climbs and bends.

So, too, a poignant time for London’s airport, Heathrow
Which was opened this week seventy years ago.
Heathrow has seen it all: Brinks-Mat, Concorde and the Beatles
It’s a melting pot of global travel, a connection for the people.

The final creation for the week was that of a humble new fiver
It will now be printed on polymer to make it more of a survivor.
It will last much longer, be much stronger and even go through the wash
Though, ironically, forgery will be harder, money laundering will get the cosh.
