World Guide to Covered Bridges
The World Guide to Covered Bridges (WGCB) is a covered bridge numbering system. The system was invented by John Diehl, the chairman of the Ohio Covered Bridge Committee. The committee first used the numbering system in 1953 to publish a list of covered bridges in Ohio.
