Dark underpasses can be avoided by splitting the "bridge" into multiple smaller bridges.

Example of a "6 lane" split into 6 smaller bridges: https://goo.gl/maps/V84SqmbjkASapyxQA

This allows for a lot of light and no overhead lights are needed.

(my gut tells me this design was used to improve maintainability: you cannot completely close the bridge or highway as the city is too dependent. But they could get away with closing 1-of-5 bridges for some time).

Five of the six bridges carry railway lines.

I think the design is more likely because the tracks are very close to a station, so they're spaced widely to allow for the platforms.

The station is very small and cheaply built, so it might have been cheaper to make two tracks on one bridge and then have the "people platform" on each side of the tracks instead of between.

Just like this place: https://goo.gl/maps/gwfGxdxDs4sbpF2S7
