Rockdale

Built around a stop on the Milwaukee Road railway, Rockdale grew into a small mountain community on the South Fork Snoqualmie River in Washington’s Cascade Mountains. The settlement lies beside Interstate 90, within the steep, forested corridor leading toward Snoqualmie Pass. Its rail heritage continues on the Palouse to Cascades State Park Trail, which follows the former Milwaukee Road grade through this section of the range. Nearby, the Snoqualmie Tunnel, completed in 1914, carries the route beneath the pass. Rockdale illustrates how rail construction and later highways threaded through this rugged part of King County.
