The Adams Avenue Parkway is a 0.5-mile (0.8 km) private toll road in the U.S. state of Utah connecting U.S. Route 89 (US-89) to Interstate 84 (I-84) near Washington Terrace, Utah. The roadway opened in 2001 at a cost of $8.9 million and was created after decades of requests by locals to connect the existing Adams Avenue to I-84. This allowed commuters to bypass the rest of US-89 through Washington Terrace to I-84.
