My God man, don't you realize how much busier the California ports are. You are suggesting the city manager of LA go to Mayberry to learn about traffic control. For example Abbott said Houston should be used instead of California. Well, modern merchant ships can't go through the Panama Canal. And the ports have a ginormous capacity difference:
Houston is the nation's 6th largest container port. But in 2020 it handled at equivalent of 2.9 million 20-foot containers of cargo, which is how volumes are measured. That's a fraction of the 9.2 million handled by Los Angeles alone, plus another 8.1 million at Long Beach.
As to the racism aspect, make up your mind what we want to care about. Look up "Black Bottom" Detroit, torn down for a 1 mile interstate. Mainly poor but with some middle class. In that area were over 300 Black owned businesses. In the mid 60s, what do you think happened to those businesses? Do you think they moved to Vail and began anew?
Google the issue. You will read about areas in Baltimore, Columbus OH, Detroit called "tight knit Black communities" being torn down for interstates. Black owned businesses closed. Now this was the era of redlining, people were not given loans to buy into those areas. As a result the FMV of those homes and businesses was unfairly depressed. Those individuals did not get fair compensation. So they had troubles starting anew, often having to move into even worse areas because they weren't allowed and couldn't afford better.
Sometimes highways were placed specifically to create barriers. In Detroit, the 8 Mile Road served that purpose for a while but was inefficient. So a wall was built to keep Blacks out:
From highways carved through thriving ‘ghettoes’ to walls segregating black and white neighbourhoods, US city development has a long and divisive history
www.theguardian.com
So it is obvious from that article that roads were used that way because the bloody thing had a wall added to it to make sure.
In reading about Baltimore, Columbus, Detroit, the areas destroyed were working poor neighborhoods. So we destroyed working poor neighborhoods, churches, busiensses, schools, and now gripe that those same people won't work? Can we make up our minds of what we want?
There are a lot of maps in the WP article below. Time after time after time roads and railroads cordon off Black areas from White. In the era of redlining, mixed neighborhoods were ineligible for loans from banks or FHA. If a barrier existed that allowed one side to show that they were not racially diverse, they could get the loans. That happened.
Below is St Louis, Mc can let us know if this is accurate?
The image won't show up. Mc, is Delmar Blvd a dividing line in St Louis?
But back to the point on the overpasses, the book that tells the story is from a guy who worked for Moses. Sure, it may be made up. But why can't anyone accept it may be factual?
