A road network isn't the only solution. In the early 20th century, for example, there was a separate narrow-gauge tunnel network beneath Chicago dedicated to freight. Deliveries were made directly to businesses via subbasements or elevator shafts. The network had stations at rail and ship terminals for accepting freight arriving from outside the city. At its height in 1929, the network had 150 locomotives pulling 10 to 15 cars per train.

Also perhaps worth mentioning in Chicago is Lower Wacker Drive.
It's a split-level street, more-or-less with local traffic on the surface and with through traffic at the subterranean level. It's a quick way to get through the area.
And beneath parts of that that is an road I've heard referred to as Lower Lower Wacker. This is almost entirely the realm of delivery and service vehicles (except for a time in fairly recent years when those darned kids were using it for drag racing at night).
It's all crazy-expensive to build anything like underground local delivery rail and underground roadways.
(But the stuff at the surface is crazy-expensive, too, and often can't be expanded horizontally without demolition of the very buildings that it seeks to benefit.
But expanding down? Sometimes, yeah -- that can happen.)
This is neat but also seems like an insane solution to the problem of “I don’t like seeing service trucks”. How many such tunnels and elevators would it take to supply the buildings in a typical city’s downtown area?
And what else could we do with that investment?
