A crane and what looks to be pilings were evident today in the parking lot at the corner of Sixth Street and Washington Blvd, site of the future Monaco Towers. Renderings of the towers can be viewed at the wired forums. The two Monaco towers are to built north of the the existing Doubletree Hotel on the south side of Sixth Street. The Sanremo will be built to the south. In the below photo, the Monaco towers will be to the right of the existing hotel.

UPDATE

Ground breaking is pretty much confirmed with pilings being driven directly into the parking lot. More Photos on the Photoblog
