It also marks the completion of a new Riverwalk from Michigan Avenue to Wabash which houses several outdoor restaurants and bars.
A walking path has also been extended that leads to Lake Michigan.
"The river has played an integral part in the city's past, and the Riverwalk will play a vital role in the city's future. It will be a place of recreation and reflection, a place where office workers and families can relax and a great place to get a bite to eat," said Thomas Byrne, Chicago Transportation Dept. Commissioner.
Work is now underway to extend the Riverwalk to State Street.
