Historic bridges of Yosemite Valley under siege

YOSEMITE NATIONAL PARK, Calif. (AP) — Perhaps no river crossing in Yosemite Valley has been more photographed than the historic Stoneman Bridge: a single, arching span faced with rough-hewn granite that provides a dramatic foreground to Half Dome, the park's most iconic natural marvel.

Yet the 205-foot bridge is slated for possible removal under proposed plans for restoring the natural flow of the Merced River. As a federally designated "Wild and Scenic River," some say its course should be shaped only by nature as it meanders through the valley — and bridge abutments alter that course.
