In a quiz, I got a question where one had to complete with に、を、で or が the
following sentence:

> この道（？）まっすぐ行ってください。

The correct answer being:

> この道 **を** まっすぐ行ってください。

It always seems more natural to me to put で here instead of を as 道 describes
where the action will take place.

Could anyone please give me the reason behind this choice in Japanese?

この道をまっすぐ行ってください。 Why を and not で?
There are basically four choices with motion verbs in Japanese. Each has a
slightly different implication.

  * に - "to" indicates the final goal of the travel. If chosen in your sentence it would be slightly nonsensical due to the この "Go directly to the street right here"
  * で - "in or around" tends to indicate meandering inside of the boundaries of a location. In other words, で treats the street not as a path to travel along, but as a place to move around inside of. This might be appropriate if you were at a street-fair or similar event (although this would probably be better with a verb other than 行く). In this case, however, the まっすぐ contradicts the implication of で, so it's not appropriate here. (EDIT: As several commentators have pointed out, で is a reasonable choice if there is a discussion of which way to travel. But this requires a context in which the conversants are discussing different options: "this road", "that sidewalk", "hang-gliding")
  * を - "across/along" indicates traveling the length (or a significant portion thereof) of the road/mountain/sky/(distance). More details are at [this question](https://japanese.stackexchange.com/questions/3243)
  * へ - "to" - very similar to に, and [へ can be replaced with に](https://japanese.stackexchange.com/q/2166/29) in pretty much all situations involving movement verbs. There is a slight emphasis on the "direction" with へ, such that へ is often called the "direction particle", as opposed to the "destination particle" に.

There are, of course, other possible particles for marking destinations, such
as まで, までで, までに, the catch-all topic marker は, and even simple omission.

answer
Building off of jkerian's answer, here are some translations which illustrate
why を is the correct choice:

> この道でまっすぐ行ってください。
>
> Please go straight in this road. (nonsensical)
>
> この道をまっすぐ行ってください。
>
> Please take this road straight ahead.
