Mikkel,

You have exhausted my store of knowledge on the drying time for large timbers. However, Al Anderson at Blue Ridge Timberwrights went through a long process on the subject. The Old Salem covered bridge for the North Carolina Department of Transportation was built from recycled yellow pine. The timbers had been submerged and had to be dried to some required moisture content (I think 12%). Al should be able to give you a feel for what was required.

Hope all is well,

Grigg Mullen
