Bridge the river with a beam bridge that follows real engineering rules.
The river cuts your City in two. Minecraft blocks float in mid-air, but your bridge must obey real rules.
- New skill Building pillars, beams and a deck
- Level 3 · Dream City
- Difficulty Beginner
- Mode Creative
- Time 35–45 min
- Ages 13+
What you’ll build
Try a desk test with a ruler and books to feel how beams bend, then measure your river with coordinates. Choose equal spans, size your beams like a real engineer, and build pillars, beams and a deck. Finish by sailing a boat underneath and holding an opening ceremony.
Finish line: Your named beam bridge has equal spans and real-sized beams, with boats sailing safely underneath.
Bonus challenge: The Lake Pontchartrain Causeway in the USA is about 38 km long, with spans of about 17 m. About how many spans is that? Guess first!
You’ll need
- Stone or concrete for pillars
- Deck blocks
- A boat
- A ruler and two stacks of books
You choose
- My bridge's name
- Span between pillars (5–15 m): ___ m
- Pillar style and deck material
Stuck?
- Spans uneven? Divide the river width by the number of spans and shift pillars until every gap matches.
- Boat hitting the deck? Raise the deck to leave plenty of room above the water.
- River width off? Stand at the water's edge on each bank and subtract the matching X or Z values.
