The longest bridge in the world, having been built for more than ten years, was finally in service last week.?

Question

a.
The longest bridge in the world, having been built for more than ten years, was finally in service last week.

b.
The longest bridge in the world, built for more than ten years, was finally in service last week.

Are sentences a and b both correct? If now, how should I revise them? Are there any differences between them in meaning? Do you say "was finally in service" in English?

Thanks!

By the way, here is my another question:

Answer 1

Both of your ideas are wrong. You want to say that it took 10 years to build the bridge, not that it was built, then stood unused for more than 10 years before being opened last week, which is what your ideas say.



Try: "It took over ten years to build the longest bridge in the world, and it finally came into service last week", or "The longest bridge in the world was opened last week, having been more than 10 years in construction".

Answer 2

The longest bridge in the world, built more than 10 years ago, was finally opened last week.

Answer 3

Your sentences are saying that the bridge has not been in service during the 10 years since it was built and both are correct if that is what you mean. If you mean that building the bridge took 10 years to build then TheScilianSage has given a good alternative to your example.

Answer 4

Both of your sentence constructions imply that the bridge was built ten years ago ! You need another verb to explain that "it has taken ten years to build."



"The longest bridge in the world, which has taken ten years to build, finally went into service last week".







And also, the words "in service" are not normally used in reference to a bridge. A machine, or a vehicle, which DOES something, or has a FUNCTION "goes into service." A bridge does not actually DO anything. The usual way of describing it would be



"the bridge was opened" or "opened to traffic"

Answer 5

we do say finally in service. example: the longest bridge in the world, having taken more than ten years to build, was finally operational.

Answer 6

The longest bridge in the world, under construction for more than ten years, was finally placed in service last week.
