230AM ON INTERSTATE 25, NO ROAD LIGHTING, NO TRAFFIC NEARBY. BY OURSELVES, FOUR OF US ON THE WAY TO THE AIRPORT. SET CRUISE CONTROL TO 75MPH. SECONDS LATER ALL LIGHTS INCLUDING DASHBOARD WENT OUT. IN TOTAL DARK NESS. GUESSED SIDE OF ROAD. MANAGED TO STOP CAR. TURNED OFF, BACK ON, ALL RESTORED. WE ACTUALLY GRAZED AN OVERPASS WHICH I HAVE ATTACHED PHOTOS. WE FOUR CAME NEAR DEATH. SCARED TO DRIVE CAR. JUST HAD "PATCH" WORK DONE AT NEARBY DEALERSHIP TO REPAIR ABS AND TRACTION LIGHTSS THAT WERE ON. PLEASE ADVISE.
