Tōkyō Highway Scenery
Tōkyō has a number of highways, often simple two-lane (one each way) roads, but also larger roads with two or even three lanes in each direction, plus additional turning lanes at intersections. Beyond this, there are also limited access expressways (typically toll roads operated by private companies).
See my Tokyo Metropolitan Expressway page for more detail on the Mukojima route section.
Highways
Some of the ground-level highways can be quite complex, with multiple through lanes, turning lanes, street parking, pedestrian crosswalks and trees planted along the edges, or even in the median strip. Not all roads in Tōkyō are the narrow ones that first come to mind. More photos of these can be found on my Tōkyō Street Scenery page.

Shuto Expressway
The Shuto, or Metropolitan, Expressway is a privately-operated network of toll roads around Tōkyō, which includes the iconic Bay Bridge and Bayshore (a.k.a., Wangan) Expressway. It includes inner (C1) and outer (C2) beltway routes, caller “circulars”, as well as a number of radial routes.
Much of the Shuto Expressway is elevated above waterways, as landowners did not need to be compensated.
Wikimedia has an extensive collection of photos of different routes of the expressway.

These are two useful photos of route 6, which runs along the east bank of the Sumida river. In the upper one, note how it’s raised above the floodwall along the riverbank, and its thin profile of red girders and white concrete railings. The supporting posts are fairly far apart, too.
The lower photo provides details of the upper surface. Note the use of a low concrete side on the left (typical of sections above water or lightly-populated areas) and the mesh fencing on the right (typical when crossing over major streets and busy areas such as pedestrian plazas), as well as the expansion joint (horizontal line), simple guardrail center-divider, the signage, and the light poles (with seagulls). On other stretches the light poles are in the center, and have two lamps, but are otherwise very similar.
