For now, they (technicians) are talking about failures in the foundations.

That thing looks really slender.

The bank on the right side of both pictures has clearly collapsed recently.

The more you know, the more you know you don't know.

Either a big chunk fell off or the bridge looks to have pulled apart after recent earthquakes mentioned in the report.

Who wants to go and cut the remaining strands?

 

[TugboatEng]

I think this is a case where you rent it out for military exercises.

We did this with a partially sunk barge with insufficient value to justify salvage. We towed it out to sea and the Coast Guard got to play with their guns.

 

[LittleInch]

The coast guard have guns??

Looks like a great place for a Dukes of Hazard episode.

Building a bridge right on a fault line was not a good idea.

 

[SWComposites]

There are probably lots of bridges in the greater LA area that span fault lines.

 

[hokie66]

Yes, another area not fit for human habitation.

the I-10 / I-215 interchange is directly on top of the San Jacinto Fault. My office used to be about a block away. my house was located approximately 2 miles from the San Andreas. I had enough fun with earthquakes and moved...

Of course the Coasties have guns, not everyone wants to be boarded for inspection.
Some are even dumb enough to try to run.

Not particularly well advertised, USCG has units trained in rather heavy duty law enforcement. In wartime they have been responsible for maintaining navigational aids in hostel territory.

Looks like the choice is demolition by explosives or ordnance. Nothing else would be remotely safe.

 

[LittleInch]

He didn't say what size guns....

I thought he meant a 155mm or something that would sink a boat, not small arms fire.

Not 155mm, but some of the Coast Guard ships have the BAE Systems' 57mm Mk110 guns, a bit larger than small arms.

 

[TugboatEng]

From the slug that landed on our boat I would guess it was some type of 20mm sabot round. It was smaller than 20mm but too long to be a 50 cal.

If you dig into the history, a 5-inch main gun wasn't unusual for the Coastguard on their larger ships. One of the purposes of the big guns on a cutter is to disable/sink any merchant ship that refuses to comply, or to sink derelict/ghost ships for safety.

A friends' daughter was an armorer in the CG. "My gun shoots over the horizon" she said

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Wonder how many crickets were on the bridge at the time
