I'll start with an historic photo -- prior to 2003, US 26 met US 30 in Astoria:



OR 22 meets OR 130 in a spot called Dolph Jct:



A couple pix I used earlier in the game -- US 20 and OR 34 in Corvallis, followed by OR 126 and OR 36 in Mapleton:

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.

This is so one year ago.... (https://www.aaroads.com/forum/index.php?msg=2915005)

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.

Ah, that would make sense why it triggered my memory then.

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.
