History of the Leo Frigo Memorial Bridge

Before constructing the Leo Frigo Memorial Bridge, the city recognized the need for an updated structure. Traffic congestion was building as early as the late 1970s. At the time, two bridges provided avenues across the Fox River. They were the Walnut Street Bridge and the Mason Street Bridge. However, they could not handle the increasing traffic volume.

So, the city began constructing the Leo Frigo Memorial Bridge in 1979. It was completed in late 1980 and opened for traffic in 1981. Now, over 40,000 vehicles use the bridge daily.

When the bridge originally opened, it was named the Tower Drive Bridge. That name got updated in 2002 to honor Leo Frigo, a prominent Green Bay businessman and philanthropist. Frigo, who passed away in 2001, was most well-known for founding the largest food pantry in the nation.

How Big is the Fox River?

The Fox River is the primary tributary for Green Bay and the largest Lake Michigan tributary. It spans a length of 200 mi (320 km) through the state of Wisconsin. Its impressive size crosses seven distinct watersheds throughout the greater basin. The Leo Frigo Memorial Bridge lies within the boundaries of the Lower Fox River Watershed.

Its name comes from the name given by French trappers and traders: Rivière aux Renards (or ‘River of the Foxes’). And this important body of water supported multiple Native American tribes over the years. Archaeological evidence suggests that human inhabitants lived in the region as far back as 7000 BC.

In modern times, it became a hub of fishing and fisheries until pollution built up too much. But the river is still home to many species within the water and along its banks.
