I know next to nothing about bridge construction, but it seems pretty obvious to me that an extra lane on the bridge means you need to provide extra lanes on the approaches too. That either means new approaches or upgrades to the existing ones. So it's perfectly reasonable to include costs like the Royal Ave. overpass in the cost of the 6-lane bridge. Those kinds of costs wouldn't be incurred in a 4-lane bridge if the alignment was reasonably close.
