Why hang the pedestrian bridge below the highway bridge?

There are several reasons that make sense to hang the pedestrian bridge below the highway bridge.

• The experience of using the bridge will be enhanced by separating the pedestrian and bike bridge from the vehicle traffic and placing the bridge closer to the water. It is the hope of the City and the designers that walkers and cyclists will slow down and have a chance to observe the river from the vantage point of the bridge.
• The safety of the pedestrians and bicyclists using the bridge is greatly improved by separating them from the vehicle traffic.
• This concept makes the whole bridge narrower and reduces the footprint of the structure in the river and on the land. The reduced footprint creates less impact on the river and creates less shade on the banks.
