Speaking of Oregon and the eclipse, it took 6 hours to go from Salem to Portland, thanks to Oregon DOT's lack of traffic management. No flaggers out on the onramps, barely any incident response crews to clear the many small collisions and accidents, and the VMS signs were turned off for the most part.

Total failure on their part. I'll be headed (and staying) to Dallas for the 2024 eclipse.
Not really shocking considering how incompetent ODOT and WSDOT are. I heard there was a bad choke point where they had a highway closed down to 1 lane because of construction. You'd think they'd find a way to open that road for the eclipse or manage the traffic. Nope! Ha!

I-87 Tappan Zee Bridge

The New York Times posted a great article about the opening of the new Tappan Zee Bridge.

Interstate 70, Denver, Colorado

Kiewit Meridiam Partners Selected to Build & Operate Central 70 Project

CDOT and HPTE select partner to deliver largest-ever infrastructure project; selection begins negotiation process to finalize contract

CDOT announced today that it has selected Kiewit Meridiam Partners (KMP) as the preferred proposer to design, build and finance the reconstruction of I-70 in Denver, as well as operate and maintain Central 70 for 30 years.

* KMP's bid is within CDOT's project budget.
* KMP's construction schedule shaves a full construction season off the CDOT project schedule.
* KMP's construction-phasing plan in the viaduct section requires only two major traffic switches.

KMP will undertake the largest infrastructure development project in CDOT's history, a $1.2 billion project that will reconstruct a 10-mile stretch of I-70 east of downtown; add one new Express Lane in each direction between I-25 and Chambers Road; remove the aging 53-year-old viaduct; lower the interstate between Brighton and Colorado boulevards; and place a four-acre park over a portion of the lowered interstate between Clayton and Columbine streets.
Full press release: https://www.codot.gov/news/2017-news...contractor-kmp

It is the largest single project in Colorado to date.

Even larger than the construction of I 70 inside Glenwood Canyon?

The Glenwood Canyon clocked in at $ 490 million. But that was 1992.

I can't wait until the 2024 eclipse. It will pass almost directly over Buffalo.

It's also amazing how fast the Tappen Zee Bridge was built (actually it wasn't that fast). Now the governor is throwing Upstate a "bone" by installing AET gantries on I-190 at the Tonawanda/Niagara Barriers, making the Grand Island Bridges cashless.

A lot of buzz words and fluff but when you get down to it, 1 express lane in each direction is the only increase in capacity and it's the most expensive infrastructure project in CDOT history?

That corresponds roughly to 850 M$ of today, so still not enough.

I do not want to detract from the ongoing human tragedy in Houston and parts of Texas, but relevant to this thread at least, what are the realistic implications of the flood on Houston's giant freeway system? I have seen photos of large stretches of interstate underwater, including complex elevated interchanges, their ramps and supporting columns. What effect would prolonged exposure to deep water have on these structures?

Probably not much. Houston is prone to flooding, and flooding events are not particularly uncommon in the area, (though, granted, flooding of this scale certainly isn't typical). That said though, the engineers that designed much of the city's infrastructure probably had enough foresight to consider the possibility of flooding and design the structures accordingly.

This event is probably worse than Allison in 2001

It's probably so, given Harvey was a category 4 hurricane at its peak while Allison was only a tropical storm, one of two tropical storms to have its name retired without ever reaching hurricane strength, the other being Erika. At the other end of the spectrum sits Emily, the only category 5 hurricane since the current lists are used not to have its name retired.

The category seems to be less important than the fact that this thing stalled and moved veeery slowly. Made landfall near Corpus Christi Friday evening, just stopped raining in Houston yesterday evening; today they're talking about Beaumont and Port Arthur - parts of that area got two feet of rain overnight.

INCREDIBLE JOB DALLAS!
Looks like some of the interchanges I have designed in my doodle pad.
