All is quiet on the existing bridge. Project leaders closed down Hwy 61 as a safety precaution while the new Main Span was being lifted into place.

Spectators watched throughout the day as crews worked nonstop to lift the bridge into place.

Looking eastward, crews are working hard to get the span aligned with the skid system so it can get moved into place.

One of the strand jacks up close. There were four used to lift the bridge. Each jack has 54 strands, which are made of high-strength steel and are about 18 millimeters in diameter.

The strand jack sits at the top of Pier 5, waiting to connect with the Main Span.

Great precision is needed when moving such a large and heavy structure.

By the morning of September 24, the new Main Span is in place next to the existing bridge. Traffic is reopened at noon – ahead of schedule.

Sept. 7, 2012 - Main Span move

hastings bridge

Early on Friday, September 7, the Main Span starts to make its way down to the river.

The Main Span is 104 feet wide.

The Main Span sits upon the Self Propelled Motorized Transports that are used to inch it down to barges in the river.

Crews started moving the Main Span early on a Friday, September 7. By early afternoon, the Main Span is making its way down a platform connecting the staging area and the barges in the river.

Looking between two girders before they are moved into place. The pier at the other side of the river is Pier 5.

hastings bridge

It’s helpful to have a number of cranes on site for complex projects like moving 115-ton concrete girders

 

March 2012

hastings bridge

There is very little wiggle room when placing one of these girders. There are little “nubs” on the pier that need to line up with holes on the bottom of the girders.

hastings bridge

Another massive concrete girder arrives on site.

The girder and truck with specialized trailer make the descent down to the staging area. A spotter (on the left) walks alongside.

It takes a pretty heavy duty crane to lift 116 tons.

With three girders in place, a fourth is slowly brought in.

Girder length:  174 feet.

After a wet spring and summer created challenges for the project, excellent fall weather resulted in a flurry of construction and produced this late fall sunset over the Mississippi River.
