Continuous Beam or Bridge

Beam having more than two supports, or bridge having ing three or more piers, the chords of the bridge being unbroken over the piers. Continuous beams are of common use in structures, but continuous bridges have been but little built on account of the uncertainty of the stre es, caused by variations in the level of the piers. Drawbridges, however, are generally continuous. The Victoria bridge at Montreal is formed of spans continuous over three supports. The Britannia tubular bridge has four continuous spans, two of 460 and two of 230 feet.
