Someone at Virginia Department of Transportation is in trouble for messing up the signage at Sycamore Street exit along I-66 above the newly opened auxiliary lane..It is going to cost a few thousand $$$ to fix this inadvertent error.  Interestingly,  the old signage (still visible on Google Maps), shows the correct spelling.
