I took these pictures at the same time I took the 441/442, so I am extremely late. Nonetheless, the bridge from Wonderland Station to Revere Beach is complete, and here are some pictures of it.

Parts of the bridge are NOT finished…
Two views of the bridge. 
This looks like one of those 3-D construction models to me. 
What a lovely view of the parking lot (my father would remark that those lights don’t have to be on during the day).
And again! Beautiful!
A marginally better view, but not that much better.

Overall, a very nice link between Wonderland and Revere Beach. I doubt it will be used very much, since Revere Beach Station is the more obvious choice, plus a lot of the beach attractions (namely, bathrooms) are closer to Revere Beach.
