When a segment of the canal was relocated as part of the Millennium Link, it needed to cross the Antonine Wall, a Roman-era defensive perimeter and UNESCO World Heritage Site. Rather than disturb it, the new canal was built into a tunnel below.
- Role: turning point
- In the article: The relocated canal had to cross the Roman wall, so it runs through a tunnel beneath it, and two new locks lift boats the rest of the way after the tunnel.
- Why it matters: It forced a design choice that explains why the Falkirk Wheel does not lift boats the whole height.
