> having more places to walk, bike, and explore that aren’t just cookie-cutter boilerplate-esque suburbs and freeways would be really nice.

We're at a critical juncture here in the Twin Cities. The state DOT needs to re-build the interstate that cuts right through the entire metro area (I-94) for the first time since it was first built 50 years ago. There is a serious proposal to remove the interstate entirely and replace it with a street. This would be amazing, the area around I-94 is, as you'd expect, quite unpleasant to be in. It's noisy, dirty, and dangerous. The interstate is infamous for being one of those roads that was planned to run through and destroy working class and Black neighborhoods in the 50s and 60s[1], and removing it would go some way to regaining what had been room for people to live. I think it's a bit of a longshot, but dang, I would love to see the cities recover that space for the people who actually live here, not just those who are driving through it. It's a once-in-a-lifetime opportunity and I'm really hoping we don't blow it by just rebuilding the stupid thing.

I-81 through Syracuse NY is being torn down. There is already a bypass, I-481 that loops around the city to the East to connect with I-90.

Very similar story - the highway divides Syracuse University from the poor Black neighborhoods. It's a scar through the middle of town.

I'm very excited to see how the city heals around it.

[coldpie]

Congrats, that's huge!

[yawgmoth]

I-375, along the northeast of downtown Detroit, MI, is being replaced with a boulevard.

[jnwatson]

Houston is about to remove the Pierce Elevated, a section of I-45 that separates Downtown from midtown. This is a very big deal.

[hobs]

I live in the twin cities and I had no idea that was even on anyone's mind, I love the idea.

[coldpie]

Please, please (please) contact everyone you can think of to support the idea. MnDOT has contact info on the Rethinking I-94 page[1], tell your city council rep, your county commissioner, your mayor, your state legislators, the governor. Tell your friends and neighbors. It's so easy to just fall back and do the same thing we've always done; making a change is really hard and we need to show that there is support for it.

[1] https://talk.dot.state.mn.us/rethinking-i94 The official term for the proposal to remove the freeway is "at-grade alternatives".

[hobs]

I will do this thing you say.

[earthling8118]

I find it interesting to see the words "twin cities" referred to here as if we all know what that is. I can see that this is referring to Minneapolis as per the link, but without that we would be left to guess.

Here's a list of many twin cities https://en.m.wikipedia.org/wiki/Twin_cities

[fennecbutt]

Tbf I thought it was common knowledge. My home town's sister city is Mishima; I've been there.

[brabel]

This article[1] shows multiple cities that have done that, many in the USA. It seems that in every single case, it was always a very good thing for the city.

I'm afraid that this would wind up like Vancouver, which lacks freeways through the city and has pretty bad traffic as a result. Better maybe to tunnel it under if possible? That works well for Seattle, although we still have I5 to contend with that divides the downtown from Capitol Hill (there is talk of lidding the entire freeway through downtown).

[avianlyric]

How does a freeway through a city improve traffic in a city vs building a freeway around a city (no need to bother with the expense of tunnelling under).

Cars on a freeway are either headed to your city as a destination, in which case the speed at which you deliver them into the city doesn’t make much difference, they’re always going to cause traffic when they leave the freeway. Or the cars are headed through the city, in which I would assume most of them would be just as happy to go around the city as go through it.

So if you get to pick between through and around, why would any sane city choose to put the freeway through your city? You’re just bringing noise and pollution into your city, putting a huge great impassable scar through your city, and forcing the people who live to drive everywhere because the freeway slice up the city into segments that you move between in a car.

[eropple]

The highway under Boston has turned out to be one of the better solutions that the area could've had, I think. It doesn't mean that the highway that goes around (I-95) is unused, or even underused, but I-93/the former Central Artery going underground has allowed some really important revitalization of parts of the city while also giving pretty direct and (outside of the worst part of rush hour) quick access to most of Boston and Cambridge by car.

As forward-looking as much of the area is, we weren't getting away with "less car", and I don't think most places will today either.

[kelnos]

I was thinking about this too. I've never lived in Boston, but have visited often enough over the past 20-25 years. While the Big Dig was an awful, wasteful, corrupt project, the results -- IMO -- make it all worth it. Moving all those highways underground made quite a few areas much more livable than before.

[fragmede]

less car means ebike and scooters which are a viable option these days

[seanmcdirmid]

You can't build a freeway around Seattle unless you plan to make it float. Well, there is 405, but that is way around (and is its own chokepoint on the east side). Vancouver has much of the same problem with hills and water making it act as a choke point. I'm not sure how the Twin Cities compares.

[dghlsakjg]

There’s the trans Canada highway that skirts around Vancouver. It’s the fastest route by far whether you are going into the city or through it.

The I5 meanwhile turns into the 99 on the Canadian side of the border, and goes right through the city. It’s a nightmare since it is officially a highway, but in reality just a surface street in the city.

[fragmede]

101 in sf is the same way. it's a highway not a freeway, but it's just a city street that goes across the city.

[sfpotter]

Creating I-5 was really contentious at the time. It destroyed neighborhoods. My family has lived in the area for several generations and my parents can attest to this.

Lidding it would be great, but removing it would be better. There are loads of people who live in the suburbs north and south of Seattle and expect to be able to drive 20-30 miles each way day-in-day-out to commute. If the city continues to grow, this simply isn't tenable in the long run, because you can't grow highway capacity forever; they would no longer be able to do this, which would be good. Just rip the band-aid off.

[seanmcdirmid]

The only thing worse than having I5 is not having I5. There really isn't enough north-south corridors to replace it (15th, 99, east/west lake...really that's it), given that I5 is close to the water and a huge hill as it comes in across from UW. It is already non-viable to expect a 20-30 minute commute into the city.

We saw what happened when the Palestine supporters blocked off I5 a few weeks ago...on a weekend without a rush hour, people were stuck in traffic for hours.

[sfpotter]

There are no major highways through Manhattan. The city is better for it.

Drive around the lake if you need to get past the city.

[seanmcdirmid]

I used to commute from westchester county into midtown, and there were definitely parkways in, although I never needed to go all the way down to Manhattan itself. I would usually try to take the train though (often not possible given how westchester county is poorly connected to train stations).

[Tagbert]

Because 405 is already a a crowded route that becomes bogged down during rush hour(s). Your choices are pretty much sound, city, lake, city, or mountains if you are looking for a route through Seattle.

[aidenn0]

How do you get from the GW bridge to the Cross-Bronx Expressway if there are no major highways through Manhattan?

[mathgeek]

278 also runs through Manhattan. I assume the previous poster really means something that excludes Randalls Island and the Heights.

[resonantjacket5]

It's actually a bit interesting to see WSDOT's plan for i-5.

For capacity they aren't expanding I-5 directly, but expanding i-405 and sr167 instead for people trying to go past Seattle.

For i-5 within Seattle area, there are some 2030s plans to convert the hov lanes to toll lanes and reconfiguring the reversible express lane system. * I-5 Managed Lanes: SR 16 to Pierce/ King County Line * I-5 Managed Lanes: Pierce/ King County Line to I-405 * I-5 Managed Lanes: I-405 to US 2

https://www.psrc.org/media/4840

[seanmcdirmid]

I don't see that working out. I405 is often worse than I5, it is just as bottlenecked as I5 is, and there isn't much room to expand it especially when it runs right up next to the water.

I feel sorry for anyone who has to actually do that commute. It was horrible when I was living in Bothell and attending UW 30 years ago.

[resonantjacket5]

They are constructing it right now the expansion between bellevue to renton.

https://wsdot.wa.gov/construction-planning/search-projects/i...

The bellevue to lynnwood section was already 'expanded' a decade ago though as one can tell, it still has traffic. They're opting to increase the tolls now.

[mc32]

I think Boeing threatened to pull out of Seattle if WSDOT did not improve freeways, some years ago -getting stuff in and out of Everett is really important to them. If I-5 was torn down and only left with surface streets, what's left of Boeing would pull out and go to Kansas or some place.

[uoaei]

Can you articulate a cogent reason why people need to cross the city on such a thoroughfare just to live their lives?

[seanmcdirmid]

You are located in the north of the city and need to get somewhere south of the city, or vice versa.

You only have a few roads to do that east or west of Lake Washington. In most cases, people aren't going to downtown Seattle, downtown Seattle is just in the way.

[uoaei]

Why are those services not available in the north of the city? This is as much a planning issue as traffic is.

[mitthrowaway2]

Because nobody knows how to build a train, it's a mystery.

[kelnos]

Traffic will suck in a city that isn't designed to discourage people from driving. It doesn't matter if there is an elevated highway running through it or not; traffic is going to suck.

Invest in transit and make it easier for people to get around without cars; that's the only way to solve traffic. Building more roads (and widening existing roads) just induces more demand.

[dghlsakjg]

You completely leave out that the trans-Canada highway has a six lane bridge, and a train bridge less than 5 miles east of the downtown peninsula, and there was a conscious decision to not route the freeway through the peninsula.

Any freeway through Vancouver would have to cut through all of east Vancouver and then the downtown core then Stanley park, and they would have to completely rebuild the lionsgate bridge since it is only three lanes total, and then tear out a huge portion of the residential neighborhood on the other side of the bridge.

Why in the world would Vancouver, which is on a much narrower strip of land want to do what Seattle did and divide their city in half so people can get to Whistler 15 minutes faster.

[_whiteCaps_]

I love that Vancouver doesn't have a freeway through the city - but they've also got a relatively good transit system. IIRC it's the equivalent of 26 lanes for cars.

[seanmcdirmid]

Vancouver has some horrible stroads to make up for its lack of freeways. I wouldn't call it very nice, more like dystopian.

[kredd]

I live in Vancouver, and absolutely love how we didn’t go with the freeway idea. And traffic will suck anyways, might as well let the locals enjoy the walks and life instead.

[seanmcdirmid]

If you search for Stroads, you inevitably bring up Vancouver. You've just swapped one evil for another. I can't imagine walking along a stroad being very nice.

https://vancouver.citynews.ca/2014/03/12/metro-vancouver-str...

[kelnos]

Stroads aren't inevitable when you get rid of elevated highways. They're just yet another result of poor urban planning.

[seanmcdirmid]

Yes, they aren't. But my position is that what Vancouver has (world famous stroads) is worse than if they buried a freeway through town instead.

If someone suggests deleting I5 through Seattle and replacing it with Vancouver-like Stroads, I'm going to vote against them as fast as possible.

[kredd]

Oh, I totally agree about the stroads, I wish we could somehow make them disappear, alas impossible. They’re doing an ok job densifying some parts of them, so it’s less dead at least.

[brabel]

Ah, Sydney, Australia, has the same issue :D specially Parramatta Rd which goes from the CBD to the Western Suburbs[1]... because there were many "influential" people living in that area, they never managed to get a permit to make a freeway there... I didn't know there was a name for that.

[mb7733]

Honestly, having lived in Vancouver as well as many cities that _do_ have highways running right through town, I didn't miss that in Vancouver at all. Traffic will suck both ways, and at least Vancouver avoids having ugly, loud highways along its waterfront and through most of its downtown.

Definitely, the best case for cars is to have fast highways that bypass the city, but there isn't a lot of room with that given Vancouver's geography, so it's a lesser-of-two-evils. Beyond cars, public transit and cycling provide a better solution in my opinion anyway.

Regardless... the biggest traffic pain point in downtown Vancouver is the 3-lane (total) Lions Gate bridge.

[seanmcdirmid]

One of the reason I passed on a townhome in Wallingford with a really good view was because of the tire noise on the ship canal bridge. I’m not sure the other bridge is any better though. A tunnel under it all would be ideal.

Whenever I visit Vancouver, I find the traffic horrible compared to Seattle. It’s like…no I don’t want to drive here (to be fair, I don’t want to drive downtown Seattle either, but there is so much more going on in downtown Vancouver that it’s hard to avoid).

[coldpie]

Gotcha covered here in the twin cities -- we already have north and south bypasses in I-494 and I-694. Now we have an opportunity to get I-94 out of the middle of the metro.

[stefan_]

All cities will forever have "bad traffic". Car transport capacity is plain abysmal.

[mitthrowaway2]

Tokyo's traffic is pretty reasonable, actually. It's quite surprising. I rarely encounter a traffic light where all the cars don't make it through, unless there's construction.

This is probably because train transport capacity is prodigious, and driving is expensive.

[shiroiuma]

That's exactly it. Almost no one actually drives anywhere: most of the cars are taxis, and most of the rest of the vehicles are commercial (e.g. cargo trucks). When most of the people outside are taking a train, walking, or riding a bicycle, there aren't too many cars on the roads and consequently there isn't much traffic. The busiest places I see are near logistics centers, with lots of truck traffic coming and going.

Also, driving isn't expensive in Tokyo at all, it's actually free except on the toll highways. What's expensive is parking: with few places to park, and it being expensive to rent a parking space in your apartment, it's not that affordable or practical to drive. People also aren't allowed to own cars unless they have a place to park them, so we don't have the problem of car owners fighting over scarce street parking like many other cities.

[trimethylpurine]

I was just driving around in Seattle and couldn't help but notice everywhere I went was just a few miles away but it took 20-30 minutes because there was no highway in between. I have to wonder if that reduces or increases emissions. I suspect it's the latter since you have more cars running longer and stop/starting more often.

[uoaei]

Bad traffic is a good catalyst for spurring local commercial development, assuming zoning and other bureaucratic measures don't hamper the situation entirely.
