Daily Life Lafayette Mt. Diablo Blvd. Sidewalk Construction in Lafayette Almost Completed April 2, 2012 11:30 am The sign notes that, “Mt. Diablo Blvd Business Open during Construction”, but as you can see from the photo it looks almost finished to me. I like the cobblestone look, it makes downtown Lafayette seem more quaint.
