Last week I was on assignment to photograph the new Sauk Rapids bridge over the Mississippi River. This is a view from the Saint Cloud, Minnesota, side looking towards Sauk Rapids.
Here is a view of the Mississippi River and some of the pillars of the new bridge.
There is a park below and on either side of the bridge. Thus this circular access for walkers and non-motorized vehicles was included as part of the bridge.
Here is a view of the circular access from above. My lens is an equivalent of 27 mm and was not wide enough to include the entire structure.
