I believe the flow challenge is simply that the PSO plant absolutely must have water at all times.  When a working dam is in, the flow of the river is where the engineers say it should be (to a reasonable extent, of course).  Kayaking across a river isn't a deterrent either, parking on the west or east...not a big deal.  But a power plant without water...that's an issue.  I believe that's why you often see big berms below the current dam directing water to the west side.

What is the lifespan of the PSO plant?  Since it is natural gas-powered I assume it will be operational for awhile but I have no idea.  IMO it’s one of the coolest industrial buildings in the city. 

I know there was a jetty built to direct the flow toward the plant, you can see remnants of it.  I would imagine AEP/PSO will be heavily involved in these discussions.

I believe they are involved in all discussions, and I believe the original design shown in one of the pictures showed a section of the dam to allow water flow for the plant separate from the main flow control.

As far as the plant's life, it is natural gas and I believe I was told was shut down for a long time and then restarted in the 80's or 90's so it looks way older on the outside than it does on the inside. (I went inside a few times, but it's been about 10 years)

... a concrete rather than steel structure was chosen for the span to minimize vibrations and provide a comfortable environment for pedestrians. The broad span would have open sides and was also wide enough to accommodate benches. It would also provide Wi-Fi service to users. One reason for the amenities: pedestrians tend to shun confined bridges.

I don't know where you are going with this.   Given the drawings of the Florida bridge, it is not the same construction technique that would be used here.

And even if it is the same construction technique... it isn't like they collapse frequently.  Someone or something screwed up in Florida, no doubt.  But that isn't universal condemnation of any particular form of construction.

I meant to put more emphasis on the amenities and features of the bridge in the part I excerpted.  Thought that might be relevant.

River Parks Authority to take over pedestrian bridge project near Gathering Place

Quote
The River Parks Authority board will vote Thursday morning on an agreement with the city of Tulsa to take responsibility for the construction of the new pedestrian bridge over the Arkansas River.

The agreement calls for the Gateway Bridge to be constructed by Tulsa's Gathering Place LLC, a wholly owned subsidiary of the authority. Gathering Place LLC is the legal name given to the Gathering Place park in 2014 when it was given to the River Parks Authority by the George Kaiser Family Foundation.

The pedestrian bridge, near the 2900 block of Riverside Drive, will connect to the $465 million park, which is scheduled to open Sept. 8.

“It is really exciting to be able to partner with someone like River Parks and the Gathering Place” on the pedestrian bridge, said Nick Doctor, the city’s chief of community development and policy.

The Gateway Bridge was selected as the winner of a bridge design competition conducted by the city of Tulsa in 2017. The bridge was designed by Michael Van Valkenburgh Associates, the same company that designed the Gathering Place.

Under the terms of the proposed agreement, the pedestrian bridge should be completed within three years. The River Parks Authority would be responsible for routine and nonstructural maintenance of the bridge, with the city assuming financial responsibility for major capital improvements.

Jeff Stava, director and trustee of Tulsa's Gathering Place LLC, said he expects demolition of the existing pedestrian bridge to begin 45 to 90 days after the agreement is finalized. The design of the new bridge is expected to take nine to 15 months, with construction ranging from 18 to 22 months, Stava said.

Glad to hear this is moving forward.  How does this align with the schedule for Vision improvements to the low water dam/whitewater flume?  Hopefully all of this work will be complete at the same time as Phase 2 of the Gathering Place.
