Quad Cities Celebrates Completion of New, I-74 Bridge, Open to Traffic Friday
This morning's sunny skies matched the mood of all the elected officials and others who celebrated the completion of the new, I-74 bridge in the Quad Cities.
Four years ago, the construction team broke ground on the $1.2 billion project which includes the new, six-lane bridge and highway between Bettendorf's Middle Road and Moline's Avenue of the Cities.
All the Quad Cities mayors were on hand to thank the hundreds of people who helped build the bridge. East Moline Mayor Reggie Freeman reminded the crowd that the first span of the old, green I-74 bridge was built in 1935 for horses, carts, and pedestrians.
Illinois Governor JB Pritzker says the I-74 bridge is one of the country's primary Mississippi River crossings, and it'll provide safe transportation for commercial purposes and daily commutes for families.
After officials cut a ribbon in the middle of the new, east-bound lanes of the new bridge, crews prepared for the arrival of hundreds of people who signed up to walk on the new bridge in the afternoon.
It should open to traffic within a week, and the old, eastbound bridge will close immediately. The new, westbound lanes opened about a year ago.
