🛣️ MOTORWAYS AND HIGHWAYS: ROADS THAT BUILT NATIONS
PAGE 1 OF 5, FROM DIRT TRACE TO NATIONAL LIFELINE
WHY A "SUPER-ROAD" AT ALL?
CARS WANT SPACE; TRUCKS WANT GRADES
By the 1900s, Topic 3's car and lorry traffic could not squeeze forever through old town grids designed for Topic 1's carts and Topic 4's hooves. A motorway / freeway / autostrada / highway (names vary by country) is not just wide — it is designed in layers: limited access (on- and off-ramps only, no surprise shop driveways in the fast lane), banked turns, long sight lines, and emergency lay-bys so high-speed flow is legal and survivable. Building one is a nation-scale decision: it moves food, post, soldiers, and tourists and permanently re-zones farms into suburbs.
📌 BIG PICTURE
A cartoon definition: a motorway is a river of lane markings with rules printed on every sign — the opposite of a meandering donkey path.

Old high street: everyone shares, nobody wins the drag race
