If you were looking at the solution on steam, it's "main street" because it was changed In a later version. I believe you're playing on an older version. The reason for the change is that it was too confusing because "main street", "intersection", or "third avenue" could have worked for that slot. I'm sorry about that.
Shoot. I made a mistake and removed the word you need in the last update. I'm sorry about that. It should be fixed now. You can find the keyword you need by looking in documents that relate to vehicles or group events.
