Questions & Answers about Я пройду через парк и быстро доберусь домой.

Why is пройду used here instead of иду?

Пройду is the future tense of the perfective verb пройти.

• идти = to be going / to go on foot in progress
• пройти = to go through, pass, walk a certain distance, complete the action

So:

• Я иду через парк = I am going through the park
• Я пройду через парк = I will go through the park / I’ll walk through the park

In this sentence, the speaker is talking about a completed future action, so perfective пройду makes sense.

What exactly does пройду mean here?

Here, пройду через парк means something like:

• I’ll walk through the park
• I’ll go through the park
• I’ll pass through the park

The prefix про- often adds the idea of passing through or covering a route/distance. So it is not just go, but more specifically go through a place.

Why is it через парк, and why is парк in that form?
