Because an overpass is an ugly concrete structure - like a bridge ramp, viaduct or freeway.
I suspect that the purple indicates the extent of the elevated roadway for the Powell Street overpass. I don't think it would be a steep up and down overpass - I think it would be more gradual - plus the height to allow trains to pass below may have to accommodate double-stacked containerized cargo. (But the plan does show it going awfully far to the east, not sure why - but it'll take out the Chevron Station there.)
