TIMBER HIGHWAY BRIDGES IN OREGON

A TIMBER-DECK TYPE BRIDGE HAS BEEN DEVELOPED WHICH USES 4 IN. BY 12 IN. PLANKS FOR THE SUBDECK AND 2 IN. BY 2 IN. CEDAR OR TREATED FIR STRIPS, LAID LONGITUDINALLY, FOR A WEARING SURFACE, WHICH IS LAID IN HOT ASPHALT. A COMPOSITE TIMBER AND CONCRETE TRESTLE WAS ALSO DEVELOPED. BECAUSE OF WAR CONDITIONS, MANY TIMBER TRUSSES HAVE BEEN USED AT SITES WHERE SPANS LONGER THAN PRACTICAL WITH TRESTLE CONSTRUCTION HAVE BEEN REQUIRED. TREATED TIMBER CULVERTS ARE PRACTICAL EVEN UNDER NORMAL CONDITIONS. SELECTION OF BRIDGE TYPES SHOULD BE MADE ON COMPARATIVE TOTAL ANNUAL COST. /AUTHOR/
