Jantzen Beach Amusement Park was heralded as Portland’s Million Dollar Playground. When it opened on May 26, 1928, Jantzen Beach was the largestamusement parkin the nation. The park sprawled over 123 acres at Hayden Island at the northern tip of Portland.

Carl Jantzen had been a partner in Portland Knitting Mills when the company was formed in 1910. Jantzen’s success with designing swimsuits used by the Portland Rowing Club resulted in the name change to Jantzen Knitting Mills in 1918. Jantzen and his partners at Jantzen Knitting Mills opened Jantzen Beach Amusement Park in 1928.

Jantzen Beach survived the Vanport flood in 1948, but the people who survived moved away. The loss of people in the immediate vicinity led to the loss of patrons to the park and attendance never did reach pre-flood levels.

To help with increasing traffic flows going north and south on the Interstate Bridge, the Highway Division built a matching span to separate the northbound traffic from the southbound traffic in 1958. For about 25 years, tolls were collected to pay for construction costs.

After years of dwindling revenues, the park closed on Labor Day in 1970 and the rides were sold and dismantled.The wood from The Dipper was salvaged and was first used following the dismantling of The Dipper to build a small warehouse on SE 22nd and Division where Mr. T\'s Bakery is located and there are now new condos. A developer tore down the warehouse and sent the wood to the Rebuilding Center where Ken Forkish acquired it about 4 years ago for building booths, tables and chairs forKen\'s Artisan Pizzaat 304 SE 28th Avenue near Pine Street.
