Bridge at 69th Street

I have seen the lines running parallel to the direction of travel - as you note they seem to be caused by paving equipment being one lane wide. But have never seen the "cross-street" joints. The crews in my area seem to go to great lengths to hide them, even when paving over concrete.

Got lots of those joints down here in Niagara, although we're nowhere near either the Federal or Provincial capital. There's only so much highway money to be had, and it often doesn't spread too far from the hands that manage it.
Around here, those lines are probably more on account of the freeze/thaw cycles, and most of the lines look like dotted ones, due to the generous array of potholes.
