The Queen Elizabeth Way (QEW) is the major trade corridor from the Greater Toronto Area to the Niagara Region and to the four international crossings (Queenston-Lewiston, Rainbow, Whirlpool and Peace Bridges) over the Niagara River to New York State. The QEW carries an average of approximately 79,000 vehicles per day (about 17 percent are commercial vehicles). Summer traffic is significantly higher, with about 100,000 vehicles per day through St. Catharines. The traffic growth on the QEW has risen significantly over the past 10 years and is expected to continue to increase by 40 percent over the next 10 years. Queenston-Lewiston is Canada’s fourth busiest crossing, operated by the Niagara Falls Bridge Commission, with over 1 million trucks traveling through each year. It is also the ninth busiest passenger crossing, handling 3.3 million vehicles a year, or over 9,000 per day. The Peace Bridge is Canada’s third busiest passenger crossing, handling 6.7 million cars and 1.35 million trucks crossing in 2001.
