As of a couple of weeks ago, 95% of the trail from Bridge 2 to the tunnel below GO was paved - all that was left was about 20 metres just north of the bridge and from the excellent ariels above, this is now being graded and paved. Once there is no need for heavy machinery on that section, the temporary bridge will be removed and they will be able to finish grading the section south to the Forks - much of which was already almost ready for paving when we were there 2 weeks ago. 
The bridge AT the Forks (below, not my photo) is, I think, temporary but it is resting on what look like permanent supports so removing it and putting a 'proper' span  in place ought to be fast and easy - well, we shall see.
