She's been going to the supermarket for an hour, but she's still blocked on the way.

[Alice Chu]

1. She has been going to the supermarket for an hour, but she is still blocked on the way.
It means she started to go to the supermarket an hour ago and she is still on the way. It also means she has been on the way to the supermarket for an hour.
Is my understanding correct?

What does the following sentence mean if it is correct?
2. She has gone to the supermarket for an hour, but she is still blocked on the way.

1. She has been going to the supermarket for an hour, but she is still blocked on the way.
It means she started to go to the supermarket an hour ago and she is still on the way.

Then that's what you need to say. Your original version does not work.
She is still blocked on the way is not natural.

What does the following sentence mean if it is correct?
2. She has gone to the supermarket for an hour, but she is still blocked on the way.

It is neither correct nor natural.

How about the following?

She has been on her way to the supermarket for an hour, but she has been held up along the way.

NOT A TEACHER

Ms. Chu, when I read your sentence, I immediately thought (as it turns out, wrongly) that you meant something like: "She has been trying for an hour to get to the supermarket, but her way is being blocked by exceptionally heavy traffic this morning."

 

[Phaedrus]

1. She has been going to the supermarket for an hour, but she is still blocked on the way.

A far-fetched context could render the sentence correct, or at least not impossible, with the first independent clause meaning that she has been (regularly) going to the supermarket to spend an hour there shopping. In that context, the second independent clause could be understood to suggest that, if she weren't still blocked (every time) on the way to the supermarket (by heavy traffic that eases up after a while), she might be spending an even longer time at the supermarket when she goes there.

A: When she goes to the supermarket, how long does she go there for?
B: She has been going to the supermarket for an hour, but she is still blocked (temporarily) along the way. Otherwise, she'd be spending an even longer time there.
