Red Gate Road Bridge



This new 1,150-foot bridge links Illinois Routes 31 and 25 over the Fox River in St. Charles, Illinois providing a connection for both vehicles and pedestrians. Because of strict environmental laws and shallow river levels, McHugh could not use causeways or crane barges to build the new structure so a temporary bridge was constructed to provide access to the river for the installation of seven new pier foundations. Once the piers were constructed, the pedestrian cable-stayed bridge was erected followed by seventy five, 5-foot tall roadway steel bridge girders.

The roadway deck was poured over a two-day period placing over 1,200 cubic yards of concrete. Steel railings and ornamental precast pylons were also installed.

Additional work included widening Illinois Route 31 and Route 25 on each side of the river, installing new traffic signals, installing precast retaining walls, and curbs in order to connect the new river crossing roadway.

The bridge opened in December 2012 but work will continue into the spring including the removal of the temporary bridge, constructing over 1.5 miles of multi-use trails, ¼ mile of emergency vehicle road, elevated timber boardwalk structures connecting to the cable-stay pedestrian bridge; painting and anti-graffiti coating; and extensive landscaping including planting over 500 trees.
