@engineered.against: Ever wondered what these metal teeth at the ends of bridges are? They’re expansion joints — built into the roadway so the bridge can expand and contract with heat and heavy loads without cracking. Instead of leaving a wide straight gap, finger plate joints interlock like teeth. This lets the bridge breathe while keeping a sealed, continuous driving surface. Wheels never hit the full gap at once, which makes the ride smoother, cuts down noise, and reduces stress on the bridge itself. #engineering #engineeredagainstyourwill
