I-35/I-44 Interchange

[Plutonic Panda]

Thanks. I didn’t see it in a quick trip through the ODOT 8 year plan I looked at this morning. Any idea how much it is projected to cost? Keep thinking that 4 miles of going from 2 lanes each way to 4 in the center of town is gonna be very costly.

Pardon me, I went and dug further to make sure I was remembering things correctly. I’m still not quite sure about it all but here’s what I found.

First off here’s a link to preferred alternative which widens the entire road to six lanes plus auxiliary lanes where needed. It also completely reconstructs the existing road and service roads. It competes the current gaps in the service roads and changes them to one way. That project is somehow expected to cost $15,000,000(which I’m not understanding how that’s possible) and begins in 2031. Again, here’s a link to the preferred alternative chosen back in 2020: https://oklahoma.gov/content/dam/ok/...218/update.pdf

Now there is some sort of a project in 2028 which will do something and cost 50,000,000 dollars worth of work for something 0.790 miles long. So whatever it is it’s big. It says I-35 grade, drain, bridge, and surface and runs from 15st to the Oklahoma River impacting both NB and SB lanes. Bottom of page 63: https://oklahoma.gov/content/dam/ok/...CWP%20book.pdf

Here is additional link from an interactive map and another link to the project webpage:

I am guessing the massive 2028 project is the new suspension bridge and widening. I expect this gets bumped up if the Olympic events come to fruition.

Granted the events most speculated to be here would not need the bridge modified, as take place entirely on the whitewater course. So we would also need to get the flatwater events too for the bridge project to have that kind of urgency.

Yes, it's $50MM for rebuilding the I-35 bridges across the OK River with a suspension feature and a pedestrian path and viewing area:

That has to be waaaaaaay more than 50 million. I’m no engineer but aren’t they rebuilding it from scratch also to remove the piers for competition rowing? We’re talking about a 14 lane suspension bridge with a pedestrian path. I’m assuming there is more sources of money that will be involved?

The Saint Anthony Falls Bridge in Minneapolis, coincidentally an I-35 bridge, collapsed in 2007, and was replaced quickly using a 90/10 federal/state match in 2008. The bridge crosses the Mississippi, but that’s near its headwaters and the river there is pretty narrow. The bridge looks similar in scale to what this bridge would be, but it was post-tensioned concrete and nothing fancy or especially expensive; what was most important was to get it finished quickly.

That bridge cost $234 million. In 2008.
