Wooden Arch Bridge Construction

木拱廊桥营造技艺

Song Dynasty (960–1279 CE)

The traditional craft of building wooden arch bridges in Fujian and Zhejiang provinces uses interlocking timber beams with mortise-and-tenon joints — no metal nails or adhesives. These self-supporting bridges span mountain streams and support roofed pavilions that serve as community gathering spaces. The technique represents an extraordinary understanding of structural mechanics and ecological adaptation.

Mortise-and-Tenon Joinery

A traditional Chinese woodworking technique that connects wooden components without nails or glue, using precisely carved interlocking joints.

Steps
  1. Select and season high-quality timber (traditionally Chinese fir)
  2. Measure and mark the joinery points
  3. Cut the mortise (socket) using chisels
  4. Shape the tenon (projecting piece) to match precisely
  5. Test-fit and adjust until the joint is tight
  6. Assemble without glue — friction and compression hold the joint
