Photograph by A. R.Hromatka THIS AWESOME CHASM YIELDS AT LAST TO ENGINEERING SKILL The new highway bridge across the Grand Canyon opens north-and-south travel between Utah and Arizona. Over itmen and goods move freely now, between busy, populous regions formerly separated by the great abyss. The bridge, among theworld's highest, dizzily spans the stone-walled gorge at a point about 135 miles north of Flagstaff, Arizona. Its two parts were joined 475 feet above the turbulent Colorado River. One half of the arch was completed before the other was started. From the end of the completed half a cable car was operated totheopposite rim, hauling men and materials. This was necessary because there was no other satisfactory means of conveying theheavy pieces ofsteel tothe north rim.
