Commons Park connects downtown Denver to one of Denver's original urban neighborhoods, the Highlands, via a series of three pedestrian bridges.

From LoDo the first bridge, Millenium Bridge, spans over still active railroad yards. The second bridge, the platte river bridge is less grand in scale but crosses over Denver's largest river the Platte. The third bridge called Highlands bridge takes travelers safely over the always busy I-25 freeway.

The bridge project opened in phases starting in 2002 and ending in 2007. With much more infill from the Union Station development and projects on both sides of the bridges coming, the bridges not only provide a means to traverse the city but also provide another great public space in the city.
