The Rainbow Bridge was built near the site of the earlier
Honeymoon Bridge, which collapsed in 1938 due to an ice jam in the
Niagara Gorge. Architect Richard (Su Min) Lee designed the bridge; a design also used for the
Lewiston-Queenston Bridge, approximately downriver. The bridge's
Rainbow Tower and Canadian side plaza are the work of another Canadian architect,
William Lyon Somerville.
King George VI and
Queen Elizabeth, during their visit to Niagara Falls as part of their
1939 royal tour of Canada, dedicated the future construction site of the Rainbow Bridge; a monument was later erected to commemorate the occasion. Construction began in May 1940. The bridge officially opened on November 1, 1941. The
Niagara Falls Bridge Commission chose the name "Rainbow Bridge" in March 1939, because rainbows occur frequently near the falls due to water spray and mist in the air. == Description and specifications ==
