Thank you for the MacArthur Maze collapse coverage. I am the former 911 dispatcher and I was working the police radio channels during this incident. However, I am slightly disappointed that most of the focus was on San Francisco. As this interchange sits in entirely in Oakland, Oakland should have been primary with S.F. secondary. As a life long Bay Area resident, it saddens me to see Oakland so frequently overlooked. Yes, Oakland has many issues but there is still beauty and depth in this city if you know where to look.

[@angelachouinard4581]

My brother did graduate work at Berkeley. I visited him and found a lot to enjoy in Oakland, some really great restaurants I still remember, for one thing. But yes, San Francisco blocks Oakland's sun.

[@spikeybunny6577]

I wonder if there is/were some kind of pre-arranged communication protocols/s for managing large road/bridge disasters by CalTrans or the county back then? &/or if they’ve been updated since this particular catastrophe? Not everything that works well on paper - actually works well in real world scenarios. I remember learning about the communication failures & holes between different first-responder departments & agencies during the 9/11 attacks. Hopefully they’ve been updated & tested as well.

[@oledennis6918]

Oakland overlooked? It always has been. I grew up in Oakland. Back in the 60's we rode our bikes anywhere without feeling threatened. Now I wouldn't go to Oakland without an armed guard. Now you can have it and the politicians you voted for. And for what we used to call San Francisco, all it is to me is frisco. The whole west coast is nothing but a cesspool.

The problem is that in the 1930s to the 1960s, the USA engorged itself on building capital infrastructure. If artificially kept the unemployment low and gave jobs to the unemployed after the depression and then to troops returning from war. The emphasis was in speed not quality. Now a lot of that infrastructure is decaying or collapsing. These bridges, roads and water systems were never designed to last 100 years or even 60. The problem for both state and federal US governments is that they have accumulated so much debt from decades of budget deficits, that the ability to fix or replace these assets is just not there. Nearly one dollar in five (17%) in US government budgets are used to just pay the interest bill on this debt, let alone the capital. To put it into perspective, it's about the same cost as the whole defence budget and is in the top three line items in the budget. This debt is 130% of US GDP, when most other developed nations are at 20% or less. The USA simply ran out of money in about 1975.

[@BillLaBrie]

Great, nuanced reply. Debt is a kind of time travel: we’ve pulled so much future money into the present over the last 90 years. Now that we’ve arrived in the “future,” we find it’s mostly gone.

The California freeway repair was not an engineering mistake. It was an engineering miracle to reopen the highway in 26 days. Australian implosion was a mistake. The Chicago arena collapse was a construction mistake, not an engineering one. The Michigan M-6 mistakes might be traced back to the engineers who prescribed the concrete formula as well as the contractors who implemented it.

[@localkiwi9988]

If something like that happened in New Zealand, the demolition wouldn't of even started in 26 days because of the red tape in this country.

The arena collapse in Metro Chicago... One of the first tasks I had in a manufacturing facility involved a prefabricated cabinet. What I didn't know and wasn't said in the assembly instructions was that the screws holding the various parts together should be installed and the nuts run down to just short of hand tight. That way when you arrive at the last few steps, you can shake the loose assembly and line up the last few holes. At that point you can begin to do the final tightening of the connections. That's what the engineers on this project were trying to do. The overloading of the storage area combined with not installing the temporary connection stabilizing plates combined to destroy the fragile structure.

The MacArthur Maze rebuild in California was bid at an amazing low price of $867,075 (basically the cost of the materials). There was a $200k a day bonus/fee for early/late work with a cap of 5 Million, a provision learned in the $14.8 million bonus payout for the Northridge earthquake. C.C. Myers, Inc. wrote and won the bid and delivered the rebuild in 25 days to collect the maximum bonus.

I worked for a developer in VA. Our head engineer was a former VDOT employee. She told me at every meeting they stalled and one guy would pipe up "Well, Caltrans did this" and they would say "OK". They have bee working on I66 out of Washington DC since I moved to VA i 2004. I can't imagine Caltrans taking decades on a project like that. They took only 8 years on "The Mixing Bowl" but they've gotten much slower over the years.

The M6 is like I81 in PA through VA. It’s awful. All you hear and feel is the car’s suspension. I drive that once avoiding tolls in NJ to Baltimore.

[@angelachouinard4581]

Driving north from VA I noticed real quality differences from state to state. But it's a federal highway and i always wondered what gives? At least no tolls, as you say.

[@JC-dt4jq]

M-6: Why do they continue to pave with cement? Asphalt applies quicker per mile, is quieter to ride on, and can be replaced much quicker than cement. The problem on M-6 was the implementation of small micro sections of cement for miles of roadway. Every joint corrodes with salt during winter. The joints suffered and then the "repair" was the old useless liquid tar which left its usually bumpy ride. Lack of RESPONSIBILITY as usual with road construction. Why does Michigan seem to get all of the "new technology methods" for us to be guinea pigs who have to pay more taxes?

The last one, it was not the concrete alone, it is too regular, there is a crack perfectly perpendicular at exact intervals, there must have been a problem with the rebar.

@olivier2553, I agree. They appear to be cold joints between batches of concrete or defective expansion joints.

[@aday1637]

The Baltimore-Washington Parkway was part of the I95 corridor, when constructed, and had similar problems. It was akin to driving on a washboard with heaved segments at every pour joint. Seems the sections were not connected or connected adaquately with rebar to prevent this heaving and tilting of each individual section. Eventually, after many years of toment, the parkway was covered with asphalt too.

[@walterulasinksi7031]

The extreme heat from a fuel fire can weaken the steel supporting members of any structure. It was the same type of fuel fire that caused the NYC World Trade Center towers to collapse. Once the bending point is reached in terms of heat, gravity takes over. It was not an engineering mistake. In the McArthur Maze. Merely that there was double the amount of fuel available, thereby creating a longer time for the melt period.
