I could swear we've done this topic before? 

Yes we did, and you remember it because you're the one who started the thread.

Highways Clinched on foot

TxDOT held its public meeting concerning I-345. It's official, the freeway will not be removed and will remain 6 general purpose lanes with up to 4 auxiliary lanes. But it will be moved below grade and have various access changes. 9 acres of land will be freed up by those changes, not counting the 7 acres of capping opportunities.

Bridges / Re: NTSB recommends risk asses...

Albany had 10 times the robbery rate (175.4 per 100k) as did Albion (33.5 per 100k).

This is only 5 times.

I think albany is improving, they should be reaching 10x now.

If the threshold set by AASHTO is incredibly low, then "30 times greater" might not actually be all that much higher.  Or, for all I know, there are scores of other bridges out there that are also "30 times greater" than that threshold.  That's why I was asking if it's even a meaningful comparison to make.

There has to be a threshold of some sort. You need to define where to spend money, and how much to spend. Once resources are limited, you need to prioritize. This is what actuary math is about.
As a semi-wild guess: if all 68 bridges in this list score the same as the collapsed one, and that is once in a 30 year thing among 68 at risk (wasn't there similar event in 1990s?)- individual bridge has 1 in 2000 years risk of failure.  If that is 30x too high, maybe the goal is 1 in 100k years for each individual one?
And if the cost of collapse. with casualties, cleanup and rebuild, is $10B...  with 1 in 2000 risk for next estimated 20 years- that is 1% total risk of loosing $10B, so spending $100M makes sense - but $1B remediation project isn't worth it.  That is, of course, a simplified one...

I also got my starting numbers wrong. Let's try this again:

236.5 = Albany, NY
35.6 = Albion, NY
49.4 = Wichita Falls, TX

There we go.  My point stands.

Actually, don't. I'd like to hear your unfiltered reaction to my revealing my homosexuality.

Sorry.  I had assumed you were joking about having a thing for Mac.  I didn't realize you were serious.

For what it's worth, while posting discriminatory comments pertaining to sexual orientation is explicitly prohibited on this forum, I don't actually know if that umbrella term was intended to include robosexuality.

I'm not attracted to Mac, but yes, I am gay.

I searched "walking" and did not find this specific thread, but similar ideas.

Anyway the only TM route I know I have fully walk-clinched is MD 45 BYP in Towson.  I have walked clinched some VA secondaries unsurprisingly by walking considering that I lived in a subdivision in a county as a child.

Numbers would look something like "1 estimated collision in 10 years, 1 in 100 may damage the bridge" - and suddenly those numbers are meaningful... 

I just have zero context for judging whether "30 times greater" is even a meaningful difference, whether it's a big difference or a small one.

Take crime statistics as an illustration.  In the state of New York in 2022, Albany had 10 times the robbery rate (175.4 per 100k) as did Albion (33.5 per 100k).  But I'd argue that's a meaningless comparison to make.  But because Albany is much more similar in population size to Wichita Falls (TX), then I'd say it's more meaningful to say Albany had 3.5 times the robbery rate as Wichita Falls.

If the threshold set by AASHTO is incredibly low, then "30 times greater" might not actually be all that much higher.  Or, for all I know, there are scores of other bridges out there that are also "30 times greater" than that threshold.  That's why I was asking if it's even a meaningful comparison to make.

The project page is showing that construction will begin this summer and last into 2028:

https://www.transportation.ohio.gov/projects/projects/107714

It took them over 20 Years to finally complete the widening!!! 

They'll also FINALLY be able to properly serve Midway Mall !

Hunh?    ( Oh well .. . )

Mike

I see what you did there. 

And for the record, the original Midway Boulevard/Griswold Road "crossover" interchange was one of the biggest clusterf**ks I had ever seen in Northeast Ohio.  Definitely one place to avoid during the holiday seasons of yore...
