Description 

Tamarack Creek Bridge and nearby spans over Cascade and Wildcat creeks mark a departure from the "Rustic Style" bridges completed over the previous two decades elsewhere in Yosemite. The reinforced concrete open spandrel arch bridges carry the New Big Oak Flat Road over the three creeks as they tumble in steep cascades, and takes full advantage of the scenic potential. The graceful bridges are unobtrusive and harmonize with the surrounding landscape; their stream-lined look also reflects modern bridge design, as structures were planned for higher-speed travel.
