Hack & slash Log Bridge

using round poles or logs
of similar diameters.

One suggestion for
attaching logs to each
other

using perforated strapping

Hose clamps fix the
arch piece crossings.

The ends will hinge
to the required angle.

A diagonal accross
arch peaks provides
lateral stability.

A bit of overload with
500+ pounds on one end
of the 12 ft. bridge
built with 1½ inch sticks.

A piece with tapered ends
bridges the arch peaks
to support the deck.

An evaluation setup
in Uganda.

A few sample plans
Log diameter is 1.
If you have 3" diameter logs, multiply all dimensions by 3 and dimensions will be in inches.
If you have 10cm diameter logs, multiply all dimensions by 10 and dimensions will be in centimeters.
