What the heck is it?

I have noticed this odd structure being constructed over the last two or three weeks, on the south side of Hwy. 9, between the 8th Concession of King and the western boundary of the Holland Marsh.   I have no idea what its purpose might be and there is no sign associated with it.   The exact location is on the south-east bank of the Holland River (west branch) where the river goes under the Hwy. 9 bridge.   The photo above looks west along No. 9, towards Schomberg.   If you know what this structure is, maybe you can leave a comment here as to its identity.

Please comment if you wish.
