The original unedited photo in jpeg.  

This is the first and second pass. First pass was in camera raw doing basic edits. Second pass was in photo doing some fine tuning and taking out a street sign with content aware fill.

Third pass in HDR Efex Pro 2. Use the Deep 2 preset and some fine tuning. 

Final product was done in Silver Efex Pro. Used the Full Dynamic Harsh preset with a little fine tuning.
