Wooden Arch Bridge Construction: A Living Heritage

The traditional craft of building wooden arch bridges in Fujian and Zhejiang provinces uses interlocking timber beams with mortise-and-tenon joints â€” 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.

Skills & Techniques

Mortise-and-Tenon Joinery expand_more

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

Steps

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

Tools

axe, chisel set, ink marker (modou), hand saw, plane, mallet

Materials

Chinese fir (Cunninghamia lanceolata), cedar, pine
