Per Dan's comments on the Lamar Thomas Show, he has two more months to get shovels in the ground. He made a comment about UM putting up walls, and such, I would imagine that they are creating some separation between the new dorms (almost done, but not to be occupied for 10 more months) and the parking lot where everything will be built.
Plus creating a new pathway for everyone to get into the Wellness Center during construction. I'd imagine one or both of the current bridges in that area will be shut down for the next year.
