Does the cinstruction mean the whole prodess of constructing

I'd appreciate it if someone would answer my question. Thanks in advance.

Concerning the sentence: The construction of a bridge is difficult.

Some people say in the above sentence, "the construction" sounds like the whole process of constructing a bridge, but don't say that in the case of "the reading" in the sentence: "The reading of magazines are pleasant",

Is it because the word "construction" is used originally for meaning completing something, but "the reading" isn't used for such an aim? (We very often stop reading.)
