Tower Bridge, Vertical-lift bridge in Sacramento, United States

Tower Bridge is a vertical-lift bridge over the Sacramento River, linking West Sacramento with Sacramento. Its two steel towers, 160 feet tall, carry a 209-foot lift span; the towers are sheathed in steel with X and triangular bracing and vertical slots near the top. The bridge is painted gold, with small round lights along the top chord of the truss.

Construction began in 1934 to replace an aging swing bridge that could no longer handle growing traffic volumes. The official opening took place on December 15, 1935, marking a turning point in the region's transportation development.

The bridge's name comes from its two steel-sheathed towers, which house the counterweights for the lift span. The crossing carried trains until 1962, and the tracks were removed the following year, leaving the deck to pedestrians and cars. The east-side grade crossing doubles as a barrier, closing when the lift siren sounds.

The bridge links West Capitol Avenue in West Sacramento with Capitol Mall in Sacramento through four traffic lanes. Pedestrians can walk along both sides and view the river and surrounding neighborhoods along the way.

During the opening ceremony in 1935, 1000 homing pigeons were released to spread news about the new crossing throughout California. The birds flew to different cities carrying small messages about this moment with them.
