Bridge Builder: Build & Drive

Build a bridge. Send the traffic across. Find out what holds.

Turn a few joints and beams into a crossing that can carry the load. Choose your materials, reinforce weak spots and work toward the target budget. When a design fails, follow the stress colours, adjust your structure and test your next idea.

60 PUZZLES, SIX WORLDS
Start with small coastal gaps, then take on canyon spans, icy roads, industrial drawbridges, laboratory mechanisms and driving challenges. Boats, hydraulics, portals and changing traffic give you new problems to solve.

A PRACTICAL BUILDING TOOLBOX
Connect road, wood, steel, cable, rope, springs and hydraulics where each level allows them. Use snapping, undo, redo, move and mirror tools to refine a design. Free hints and campaign examples help when you want another approach.

TEST, WATCH AND IMPROVE
See a static stress estimate while building, then run a moving load test. Vehicles have weight and suspension, bridges flex, and overloaded beams can break. On driving stages, control the gas, brake and lean yourself.

MORE CROSSINGS TO EXPLORE
Try a daily crossing, take a staged Bridge Run, remix a familiar puzzle or create a Workshop site. Share a checksummed site code so someone else can build their own solution. Generated examples are checked with the game's physics before play.

PLAY FREELY
Campaign crossings unlock as you earn passes. All gameplay and hints are free. Earn cosmetic Golden Bolts through play and daily contracts, then choose crew hats and vehicle paints. Optional rewarded ads can add 5 cosmetic bolts when available. A one-time Remove Ads purchase removes every ad, including rewarded ads, and lets you claim the same cosmetic reward without watching an ad. Both reward routes share a 60-second limit. The purchase does not unlock levels, award stars or change bridge strength. No subscription.

Progress and designs save on your device. Export a progress backup before clearing app or browser storage or moving to another device. Optional ads require an internet connection and availability can vary.
