1. Denman Street is closed for construction = Denman Street is closed because of construction ?

2.so you'll need to double back = so you will need to go back two blocks?

3. What does the man say about Trinity Way? = why not:
What is the man saying about Trinity Way?

Many thanks

1. yes
2. so you'll have to go back the way you came.
3. 'does' makes more sense in a question format, because you will already have heard the man say it.
