Am I correct in thinking that "construction" in "The construction of the bridge" expresses an action? I mean "The construction of the bridge" = "The building of the bridge"?

In that phrase, yes, but the bridge itself is also 'a construction'.

Side note:

There are many words in -tion that serve both functions. They can represent either an action or an object (the result of the action).

Yes. The noun would be the structure of the bridge.

Thank you CalifJim. Could you give a few examples of the words which end with "ition" and convey both a noun and a verb?

It's not a noun and a verb. It's that one word can refer either to an action or to a non-action (sometimes an actual object).

The action meaning is generally conveyed through "the ____ of ____", where the "of"-phrase is the complement, while the non-action meaning doesn't have the complement phrase.

These moves by the legislature represent the obstruction of the democratic process.
