Speaking of Ohio, is there some explanation on why Indianapolis has just one ring highway with few cross-city links whereas Cincinnati, Columbus and Cleveland have many more?

I doubt it. Building anything across the sound is going to be expensive and complicated. The sound is deep and the ground is unstable making building anything difficult. If they did connect to the other side of the sound it definitely would open up development opportunities. Washington doesn't have very good transportation infrastructure so I can't see it happening in this lifetime.

US 6/20/42 Cleveland

The impressive Detroit-Superior Bridge. It opened in 1918 and at the time was one of the largest concrete reinforced bridges in the world. It spans the Cuyahoga River near Downtown Cleveland.

It's a double-decker bridge, the lower level was originally for streetcars until the 1950s. It's now closed for public access.

parallel flow intersection

An intersection proposed at the US 41 / SR-54 intersection in Land 'O Lakes, Florida.

What a complicated mess, why wouldn't they build an overpass interchange instead...

it looks really simple to navigate, aside from having two lights instead of one

It looks like a disaster. They have an intersection similar to this near where I live and it's always backed up (not to mention a total death trap).

I used to live in Florida, the drivers there are pretty bad, among the worst in the US. I could see many accidents happening there.

Also there is a railroad track going through it...

It's going to be interesting to see if they install arms or if they'll just hang flashing lights from a long gantry.

Any intersection that large should be grade-separated. I guess there will be a lot of dissatisfaction and pressure to rebuild it.

Literally every person in every city on the planet says that very statement. (Insert city name here) has the worst drivers ever!

It's like how 90 % of drivers think they are better than 90% of other drivers

Or like George Carlin would say, the ones driving slower than you are idiots, and anyone faster, a maniac

Vashon Island is a major NIMBY hotspot. People deliberately more there to avoid Seattle congestion.

Regardless I think after Bertha, there won't be any tunnels being built in this state for a while.

I lived in Connecticut before I moved here in 2014. The drivers were amazing compared to here. So in my case, this is half true for me.

I've driven significantly across many US states, I have something to compare to.

The U.S. generally doesn't have that much experience with road tunnels. There are very few road tunnels compared to Europe. Norway - a country with a smaller population than Washington state - has over 1,000 tunnels, including more than 80 over 2.5 miles in length.

There are only about 15 road tunnels over 1 mile in length, according to this list and many are immersed tunnels under rivers or estuaries, less than 5 are mountain tunnels. Compare this to countries like Italy, Germany, Switzerland, Austria, Norway, etc.

I can only imagine how a 15 mile freeway tunnel would sound mind-boggling in the U.S. (one is planned to start construction this year in Norway).

Eh, not entirely. I moved from Tennessee to New Jersey and there is no comparison. The drivers in New Jersey are far worse. Not necessarily worse at driving, just absurdly aggressive. This sentiment is also reflected in the fact my car insurance tripled just by moving from TN to NJ despite having the exact same amount of coverage.

U.S. does have a lot of experience with tunnels, mainly rail tunnels, which some of them were later abandoned due to the populatity of automobile transportation. Other tunnels, were built to connect metropolitan areas and to cope with the sheer volume of traffic - therefore they are not massive and long. Vast uninhabited areas in the U.S. allowed the use of dynamite and explosives - imposible in Norway/Italy/Austria because the areas have been inhabited for hundereds of years (or could be affected by the blast i.e landslides, fractures in the rock composition).

example - The Sideling Hill Road Cut on Interstate 68 and US 40 is a 340-foot (100 m) deep notch excavated from the ridge of Sideling Hill, about 7 miles (11 km) west of Hancock in Washington County, Maryland. It is notable as an impressive man-made mountain pass, visible from miles away, and is considered to be one of the best rock exposures in Maryland and the entire northeastern United States.

So, a tunnel or a huge cut out

Number of tunnels per pop. is not a good example
