The Model 321 bridge is a through-type steel truss bridge. The truss unit features a Warren truss configuration. The top and bottom chords are made of No. 10 channel steel, while the vertical and diagonal members are fabricated from No. 8 channel steel by welding. The connection module has a length of 3000mm and a height of 1400mm.
Bracing System: Comprises wind ties and vertical struts, connected to the floor beams.
Deck System: Consists of floor beams (28A I-beams) and steel deck panels. Deck panels withstand tracked or wheeled loads directly and are fixed using U-bolts. The maximum achievable span reaches 61 meters, tailored to traffic load requirements.
