DOUBLE-DECK BRIDGE IS RESTORED

The paper reports on the restoration of a twin-deck highway-railroad bridge by replacing its outer lanes and reinforcing its steel truss while traffic flows on both levels. To strengthen the bridge's 24-in.-deep, wide-flange stringers, 12-ft-long prestress rods in brackets were installed at each side of the top of the web. Three-in.-wide compression plates are bolted in 6-ft lengths on top of the bottom flange on both sides of the web. The compression plates are welded to the diaphragm where the stringer intersects the floor beam to match the 12-ft length of the prestress rods.
