State Route 529 (SR 529, officially the Yellow Ribbon Highway) is a Washington state highway that connects the cities of Everett and Marysville. The 7.88-mile-long (12.68 km) roadway extends north from an interchange with Interstate 5 (I-5), numbered exit 193, past the western terminus of U.S. Route 2 (US 2), its spur route, Downtown Everett and Naval Station Everett to cross the Snohomish River onto Smith Island. After crossing the Steamboat Slough, the road encounters an interchange with I-5, numbered exit 198, before crossing the Ebey Slough and entering Marysville. In Marysville, SR 529 ends at SR 528. Before being realigned in 1991, SR 529 started at exit 192 of I-5 and traveled north as Broadway through Downtown Everett to Marysville.

A map published in 1895 of the Snohomish area showed the current and former routes in Everett already complete. By 1898, citizens of both Everett and Marysville were interested in a road that would traverse the Snohomish River delta. A 1911 map of the Mount Vernon area showed the route in Marysville, but the bridges between Everett and Marysville were railroad bridges. The roads were combined with other highways to form the Pacific Highway in 1913, which became State Road 1 in 1923 and US 99 in 1926, but the cutoff actually opened in 1927. State Road 1 became Primary State Highway 1 (PSH 1) in 1937 and PSH 1 became US 99 in 1964. After US 99 was decommissioned, SR 529 was established in 1971. Naval Station Everett was opened in 1991 and SR 529 was realigned on Everett Avenue and Marine View Drive to serve the new naval base. The former route of the highway, now named Broadway, had an interchange with I-5 that was reconstructed between 2005 and 2008 to include high-occupancy vehicle (HOV) lanes and now includes a single-point urban interchange with 41st Street.
