CANTILEVERED SUPPORTS AND DOLLY-DELIVERED GIRDER SECTIONS KEEP FREEWAY HIGH ATOP BUSY CITY

This article describes a method of constructing an elevated freeway above a densely populated area through the use of cantilevered supports and dolly-delivered girder sections. When completed the structure consisted of pairs of box girders set 23 feet apart and supporting the 85-foot wide, 6-lane, 11.8-inch thinck reinforced and prestressed concrete roadway. Girder depth, ranging from 6 to 11.8 feet, varied according to the length of the free span, from a short 209 feet to a 301-foot maximum. Accuracy of alignment and distance between firders was vital to the construction method.
