From the expected bid cost for Mustang Road's bridges it is not enough to be altered like Morgan Road's interchange, it is more likely being redecked and the approaches rehabilitated like what they did with Council Road's bridges a few years ago.

You are correct that the cost is less than Morgan Rd. but the SPUI is a special case/structure and is pretty expensive. You don't see too many rehabilitation projects in the 8 year plan but when they are there they are clearly denoted as such like on the SH-51 project over Skeleton Creek in Kingfisher County in FY 2014. SH-4 (Mustang Rd.) over I-40 will be a full replacement. I-40 over Garth Brooks (formerly SH-92) will be a full replacement as well. I would anticipate that the beams will be made available for reuse by Canadian County in much the same manner as they were on the Crosstown.

I think the Rockwell exit needs to be altered, half clover leafs seems like a growing problem

I would be surprised if any major change was made altering the layout on that until they either widen i40 to 8 lanes there or build a bridge over the river south of that. Widening the westbound exit lane there and at council are probably a higher priority.

South on Rockwell is the trash dump so no bridge will be going in there.

I do think that MacArthur at I-40 needs a Texas turnaround eastbound exit back around to the westbound entrance. That intersection is highly congested. A turnaround wouldn't solve the problem but it would definitely help. I say buy the used carlot, granny's music, the motel and the old truck maintenance place to put one from the westbound exit around to the eastbound entrance. Everything would help.

If the city decided that a bridge would be beneficial, Rockwell could very easily be skirted around the East side of the trash dump. It would be similar to the way they designed SW 15th to meander around the South side of the river when it was extended a few year ago.

Since the Outlet mall is expanding, its going to draw more and more people in the future and I'm sure people will be taking the Rockwell exit just as much the Council exit, shouldnt that be enough to want to rebuild the existing bridges and add more design to them like Morgan road?

They could at least resurface the Council overpass/exits..... Feels like my car will get rattled to pieces when using it.

They need to widen the Council exit going westbound and possibly lengthen it as well, it has a tendency to spill onto the roadway. However since they just re-decked it less than five years ago I doubt the bridges them-self are having anything done to them for decades.

Thats a poor excuse, theres a lot of potential land in that area, it needs to be recognized, not forgotton.

Thank you Catch22!

Thanks for taking the time to take those! Would love to see what this exit looks like from a birds eye view

I'm sure you're right. The basic intersection design at Mustang Road and Garth Brooks isn't as totally out of whack and overwhelmed as Morgan Road was.

Could not agree more but I would add Czech Hall to that mix as well. There is NO flow to traffic with these 3 exits and if there is $$ I sure hope that there is a chance of doing a SPUI at least Mustang and Garth Brooks.

Here's an animation showing how a single-point urban interchange (SPUI) works:

http://www.youtube.com/watch?v=mwpoPQ1SPJU

I think this type of interchange is pretty good. I see that it's being put in on I-35 in Norman on the Main St interchange. Is there any design in place for the I-40 / Choctaw Road interchange? Is the SPUI a thing of the future, or does it have to fit a certain criteria to be a good idea?
eta: Further, does the SPUI offer an option to change directions on the interstate? Can you effect a u-turn by turning back onto the interstate there legally?

A single point urban interchange is also planned for I-35 and Lindsey St. in Norman.

While it seems like you should be able make a u-turn from the left most turn lane, there would be no cars traveling against in that traffic pattern, the road is striped of the turn is painted not to encourage it. Not sure if there is any signs indicating it is not allowed.

yes you can if you're in the far left turn lane

I'm not sure how 'new' this style is - we have 5 or 6 of them here in Jax. They seem to work really well.

I think they are putting in another SPUI at Mustang Rd and I-40 in 2014 when the last section of I-40 is rebuilt. I read that the bridge would be a total rebuild, hopefully so.

Not to be. The shoulder to shoulder width of I-40 is too great, yielding an unfavorable time between traffic signal phases and too great a bridge cost.

I thought that "rebuild" basically amounted just a new bridge deck for the Mustang Rd/I-40 intersection... Do you still have a valid link we could check?

The Mustang Road interchange is programmed for "Bridge & Approaches", which is a replacement.

Thanks Buffalo Bill.

The document you shared lists that replacement at $7,210,000. I noticed that the SPUI for Main St. in Norman is going to cost something like $28 million. Does this mean that the new Mustang Rd. bridge will not be a SPUI? That's a very large cost discrepancy.

I think the Morgan was 30 million so, nope, it'll just be rebuilt as is.

In the Norman Transcript article, they quoted someone as saying it was cheaper to do a SPUI. Apparently not going by the numbers mentioned above, unless he was referring to maintenance over the life of a SPUI versus a traditional 4 point interchange.

You have to remember that most everything that is new to Oklahoma has been in most of the country for at least 5 years already.

The first one was built in Florida in 1974 according to wiki.. so we're really late to the party on this one.

Too bad we're also going to be the last major city to ever put an overpass through a downtown area lol

At I-40 and Mustang Road, I believe they plan on creating one wider five-lane bridge as opposed to the pairs of two lane bridges that currently exist. This will create a left turn lane in the center than can provide storage for that movement.

Hopefully when they do that they tie the signals in with Reno's light so their will be movement south.
