Brooks Edwin Tonn Memorial Pedestrian Bridge
In coordination with the Village of Hinsdale, the Village of Western Springs and the Western Springs Park District, the Illinois Tollway has built a new pedestrian bridge over the Central Tri-State Tollway (I-294), to maintain a convenient connection between Hinsdale and Western Springs for pedestrians and bicyclists.
The pedestrian bridge was relocated from its current location near Ogden Avenue to a new site adjacent to 47th Street selected by the Villages of Hinsdale and Western Springs.
The new bridge was built prior to the old bridge’s removal to allow for full pedestrian access throughout construction.
