After doing a bit more work on the station area and the new business district to the east, I think I'm finally happy with how everything's arranged (aside from RCI zones, which are as fickle as ever). Here's an updated picture of the station:
The only real change I made is turning the one-way roads on either side of the station into ramps into an underground parking garage, taxi rank, and bus stop. The land that the OWRs previously occupied is now home to a pair of short pedestrian malls; removing the extra OWR intersections behind the station allowed me to add the lane reduction I wanted on Station Street as it approaches Royal Street.
The area east of Central Station is now home to another business district along East Center Street. Most of these skyscrapers are newer as a result of urban renewal in the 1970s and '80s. They also have improved highway access, now that the R-3 has new ramps connecting to Center Street (along with an added connection to Nybro Street).
The previous view of the East Center Street District faced west, toward Royal Square. This view faces east, with the university at the top.
Here's an updated view of Royal Square at night, with the updated station and its surroundings.
To put the redesigned station and new business district into context, here's a wider shot of downtown Nyhaven, facing north. Royal Square is roughly centered; the major business districts visible here are (clockwise from top) the Financial District, the East Center Street Corridor, the Market Street Corridor, and the West Center Street Corridor. Also visible at top are Old Town (north of the opera house), with its more chaotic streets and the Western Cross Church; and the Kilterby neighborhood, with its angled grid, north of East Center Street. We'll take a closer look at each of these two neighborhoods in due time...
Finally, here's a closer view of Royal Square at night. Click on it to view (and download, if you like) a full-size version that can be used as a 1920x1080 desktop background.
Please excuse the game grid that's visible in some of the above pictures. I was having trouble with an anti-malware tool that prevented me from turning the grid off when I took those pictures.
