Making rock block walls is more efficient than raising rock block bridges.
10x1-tile bridge: I think three blocks, maybe four, plus one rock for a mechanism to raise it and one for a mechanism for connecting to the lever. Three rocks total. This doesn't account for the mechanism to build the lever, BTW.
10-tile wall: 10 blocks, 2-1/2 rocks total.
Walls also don't require architects, mechanics, or lever-pullers; a tile of wall has two jobs, make rock blocks and build building; the former is split between four chunks of wall, so it's more like 1.25 jobs/tile. The bridge needs a mason to make blocks, a mechanic to make mechanisms twice, an architect to design the bridge, a mason to build it, a mechanic to link up the bridge (effectively two jobs), and someone to pull the lever (which I won't count, to be nice and account for the above choice of counting). That's 7 jobs...okay, 0.7/tile, but still, you need to runfrom fort to bridge a lot. Also, your walls are susceptible to gremlins and crazy dwarves, not to menti0on forgetfulness.
