RECENT IMPROVEMENT ON TOWNSCAPE IS REMARKABLE. HOWEVER, OLD-FASHIONED FOOTBRIDGES ARE STILL EXISTING ON THE STREETS WHICH ARE REGARDED AS MOST INFLUENTIAL ITEM FOR TOWNSCAPE. IN NEAR FUTUER, IT IS INEVITABLE TO MAKE EFFORT TO HORMONIZE THE VIEW OF FOOTBRIDGES WITH CIRCUMFERENTIAL URBAN FACILITIES WHICH ARE DEVELOPING. IN THIS PAPER THE ATTENTION IS MOSTLY PAID ON THE HISTRICAL CHANGE OF STRUCTURE DESIGN IN VIEW OF CONSTRUCTION AND STRUCTURE TYPE OF FOOTDRIDGES. THIS IS AIMED TO SUMMARIZE THE METHOD USED TO CHANGE FOOTBRIDGE TO FIT NICELY AS A PART OF TOWNSCAPE.
