I don't do concrete roadway design, but there are a lot of factors that could cause issues that LA doesn't have. I'm fading could because I really don't know what went into the design in either location.

The concrete mix design is one thing that is pretty much impossible to comment on without seeing the original design, but could be a big factor in how the concrete holds up.

But most likely either the weather or the soil supporting the roadway is likely the largest factor in the longevity of the road. (Obviously the real answer is a combination of many factors)

LA doesn't get the same wet and freezing cycles that Seattle does (though they get way more direct sun and heat) and that can be really cause issues for roads. You'd have to ask a geotech because I don't know what the soil is like down there, but the Puget Sound region has a lot clay and silt deposits from the glaciers.

But things like that are why you can't just copy and paste a road design project anywhere in the country, or even the same county really.

I'm a truck driver and I drive to Portland nightly.

I use the left lane in a lot of places between castle rock/centralia because overloaded log trucks have made such enormous grooves in the asphalt that it can violently shake the truck to the point it's unsafe. The worst places where this is is just after the cowlitz river bridge on I5 south and just before exit 60 until milepost 65 on i5 north.

Lake Washington Institute of Technology is fantastic! Nursing, Engineering and Gaming degrees, among many others.

They just received $1,000,000 from Patty Murray to put solar panels up. Once done, we'll be the most sustainable college in the system!

Interesting, I really have no experience with concrete slab roadway design, so my ideas aren't "good" but any means, but I'm willing to guess!

My guess is it's from a repair where they ground into the slap, fixed something (rebar?) And then filled it back up.

A secondary guess would be something to do with drainage. Perhaps those spots get a little sitting water in the center so they create a little more space for it to sit as it drains, where it is less dangerous for drivers.

The entire cc system in WA is fantastic. Best value for your 2 year education imo. Depends on where you end up living though. Do you want to live in Seattle? Central or North Seattle are great. Out in the burbs? Shoreline or Edmonds are good. Wayyyyy up in Skagit or Bham? Skagit Valley or Whatcom. Good luck!

While they've recovered you can also see the spots where they've started taking from in the 2020 versions. The upper left of the Cascades pictures shows a good contrast of that. East of the Cascades also turns to dirt more quickly than 84.

You can really see how the area around Mt. St. Helens has recovered. Also interesting to note on the "Cascades" photos, most everything you see between St. Helens and Adams is the Gifford Pinchot National Forest.

Leavenworth blew up during COVID year-round but it was very trafficked during christmas lighting season for the last 10+ years. Vail actually REDUCED traffic by jacking up steven's pass prices and doing away with things like powder packs and locals days/nights.
