GANTRY BRIDGES HEAVY GIRDER GAP

The paper reports how a light, adjustable casting gantry launched from pier to pier is handling heavy 194-ft-long concrete box girder pours in the approach superstructure of a highway bridge. The gantry's two truss sections advance separately, then join to form complete spans for the twin-lane decks, which stand 4 in. apart. The bridge contains 1,496-ft and 1,302-ft viaduct approaches.
