ICG GOES TO GLU-LAM STRINGERS FOR ITS 1974 BRIDGE PROGRAM

In 1968 Illinois Central Gulf began using prestressed concrete caps in trestles. The road is now making extensive use of glu-lam stringers in its bridge-construction program. A total of 3,050 such stringers was ordered in 1974. Behind both of these changes is the difficulty of obtaining large "sticks" of timber for stringers and caps. The glu-lam stringers used are essentially the same size as the solid-sawn timbers. Although their cost is presently somewhat higher than solid-sawn material, it is believed it will be possible with increasing usage to close the cost gap between the two types.
