Over, under, or straight through the middle? It's a simple-sounding question, but it's challenged every great engineer since ancient times. We like highways and railroads to be straight and level, but Earth's bumps and wiggles make that kind of construction an amazing challenge. How do you take a highway through a valley or make a railroad cross a creek? The simplest answer is to use a bridge
One of the world's greatest bridges. Over 150 years after it was completed in 1859, Isambard Kingdom Brunel's amazing Royal Albert Bridge still carries railroad trains 30m (100ft) over the River Tamar, separating Cornwall and Devon in England. But is it a suspension bridge, or is it a truss bridge? Well, it's certainly a truss bridge (notice the thick, tubular, "lenticular" trusses at the top). The vertical ties running from the top curve ("chord") of the trusses, through the bottom curve, down to the deck mean that the bridge does not push outward on its supporting towers, though it does push its loads down onto them. But there are elements of other bridges in here too—bits of suspension bridge, bits of bowstring (tied-arch)—and I think it's a good example of how some bridges are actually hybrids incorporating several different types of bridge in one structure. A modern suspension bridge was built alongside in the 1960s to ferry cars across too
