This is Cornell's planned ultra modern Tech Campus in NYC on Roosevelt Island. And that big ugly thing bisecting the island in two is the Queensboro bridge.
I think this could be very nice. A bit of old along the new usually works quite well. They just need to make sure that they include the bridge into the design and construction in a way that it doesn't stick out like something that doesn't belong.

It doesn't look like the bridge takes up too much ground real estate, so it could probably work well. The areas under bridges are too often left out of planning and ignored as something not worthy of attention. Especially with a university campus I think it could be put to good use.

I totally get the sarcasm here. However, in the U.S. west, there are miles upon miles of nothing. When there is a possibility of someone pulling on to the highway these signs simply warn the half alert driver to be aware. This is in S.E. Oregon, a very unpopulated area. Warrented, for sure. But, agreed, a different meaning than in most of the world.

Excellent before and afters. Unfortunately the tunnel berthing instrument, called "Betha" has been having problems and will delay the project by atleast one year.

However, despite some who argue it is the wrong approach, too much money and infrastructure has already been spent. This project will proceed to the end, despite the problems. Unfortunately, this is commonplace in the Seattle area, and while the cost overuns will be there, the conclusion will be reached come hell or high water.

the entire project is such a waste, spending billions to bury a stub highway with the I-5 not even a kilometre to the north.

I-5 is so congested and can't be expanded.

SR-99 will likely collapse in a large earthquake. The intrusive view of the elevated highway from Seattle's waterfront was the main motive to replace it with a tunnel.

One problem that will likely arise is access to and from Downtown Seattle. While just over half of all traffic on SR-99 at downtown was through traffic, some 50,000 vehicles did have an origin or destination in downtown Seattle. That traffic will now be diverted to the already saturated Interstate 5, and downtown streets.

and transit. The money would have been much better spent expanding the LRT network. $2.8 billion (likely much more now given the huge delays and setbacks) could provide much more transit capacity into the downtown than this highway ever could.

I agree that Bertha was a huge waste. Another factor to consider is that the traffic has plummeted on the Alaskan Way Viaduct. If that money were used to improve public transportation and to restore the street grid in the north, it seems more than possible to move that traffic elsewhere. It's already been going elsewhere during the construction...

Traffic has declined due to construction, but not as much as that "Streetsblog" article suggests. They misread traffic data. The 2007 and 2010 AADT was 73-74,000 not 100-110,000.

I've seen figures in the 110k range before too, but according to traffic data by WSDOT it has not been that high. The 110k volumes may have been a double-count in the past (couplet + regular AADT)

Although traffic volumes on SR-99 are not sky-high, it does a good job of relieving Interstate 5 from local traffic. Interstate 5 carries up to 250,000 vehicles per day and cannot take much more traffic, nor do you want that kind of traffic on downtown streets.

wouldn't it be cheaper to order a 2nd tunnel boring machine and start digging from the northern portal while they fix Bertha?

You don't just "order" another one of the world's largest TBM. They cost over $ 80 million and take a lot of time to design and assemble.

More big delays for Big Bertha

More big delays for Big Bertha. Is this beginning to look like another Boston big dig disaster?
