The "Build Road To" worker command (Ctrl-R) works a bit differently than other worker commands. It processes the worker labor during the unit's regular rotation, rather than at the end of the turn.
If you have one worker in a tile and tell it "Build Road To" (Ctrl-R) to a neighboring tile, it will finish the road DURING the third turn instead of at the END. Keep hitting Wait for all the units until that worker gets triggered. Then, you can move troops through using the road or make use of that resource on that same turn.
Furthermore, suppose you have two workers in a tile that lacks a road. A road takes three turns to build, so if you command both workers to build the road, you waste a turn of worker labor. BUT, suppose you give Worker #1 a Ctrl-R order to build a road to a neighboring tile that already has a road. Worker #1 will apply its labor DURING the second turn instead of at the end. Then, Worker #2 will wake up and can use the road to exit that tile on the same turn. No wasted labor!
(Note that a worker under a Ctrl-R command will automatically move to the destination tile of the Ctrl-R when it can, so make sure it's somewhere you want the worker to go, or manually activate the worker before it moves on the next turn.)
Ctrl-Shift-R to build railroads has the same properties, although is less useful. The most common use is probably if you have a stack of workers on a mountain which will take two turns to build a railroad, and you will want to be able to use the railroad on the second turn to move troops.
Was this known? I hadn't ever heard of it.
