Here is an awesome video about the Ringways project in the UK and why it didn't get built; https://www.youtube.com/watch?v=yUEHWhO_HdY There's also one about railways but that's less this thread and more, another thread.

Cichlidae, this is probably going to wind up with a long answer. (at least it doesn't involve some insane, dry humping homo) If the US would not have gone through with the Federal Highway Act in the 50's and kept and maintained it's passenger rail and inner city train/public transit. How different would our suburbs, highways, and cities look now?

How different would our suburbs, highways, and cities look now? In Milwaukee urban sprawl and the exodus from the city center was starting to rear it's ugly head well before freeways were starting to become a reality. Cars were making a massive impact as a means of transportation starting in the 20s when the cheap Model T was available. Parking and traffic jams were huge problems up until WW2 slowed car production and gas supplies were hard to come by. Public transit had its highest riderships during the war. The city of Milwaukee still had enough transportation engineering clout to fund quite a few projects of its own to link newly annexed lands with efficient, modern roadways some of which were limited access. The suburbs on the other hand, could never afford modern roadways without a sufficient tax base and couldn't grow a sufficient tax base without a modern transportation system. The state has always funded its own highway system that linked cities and towns. It would be likely that they would have increased those roadways into something similar to the modern interstate system if the need grew. Suburbs would still exist but would not be the urban siphon that they grew to be without interstate highways. I don't think interstate trucking and vehicular travel would be as big without interstate highways. National rail networks would be more heavily used than now at least until air travel took over.

Freeways predate the Federal Highway Act by a couple decades, especially in heavily urbanized areas like the Northeast Corridor. Suburbs were already prevalent up here, though they were mostly clustered around streetcar lines. I believe, in the 50s, those streetcar lines were already being replaced with bus lines courtesy of GM. Also keep in mind that a large portion of the Interstates here were actually built before the Highway Act and designated as Interstate later. So it wasn't completely dependent on the Interstates, at least not in urbanized areas. I'd wager that more rural areas, like Arizona and southern California, would be much less dense than they turned out to be.

Yeah, we talked about that at work this morning. It pretty much was a freak accident. The only design that would've prevented it was an extra-high Jersey barrier, which is both very expensive and much less kind to normal-size cars that impact.

Trendy MySpace User posted:This happened a few hours ago: Aww, nice fresh pavement, too. What happens is that soil weighs a good deal more when saturated. It can also support more weight, due to the hydrostatic pressure. Seems pretty obvious when I put it that way, but there's a whole field devoted to the study. Eventually, when the stress reaches a critical point, the structure fails along a curved plane and a whole chunk of terrain just slides down like it's been scooped by a melon baller. The asphalt, with nothing left to support it, cracks along the same plane (where moment is concentrated) and falls down along with it.

Cichlidae posted:Aww, nice fresh pavement, too.  A similar accident in 1918 is one of the reasons why the Dutch became known in the rest of the world as exceptional geological and hydrodynamical engineers. The embankmant was saturated with water, and when the train rode over it, the embankment gave way and the train crashed. An investigative committee was appointed, led by the brilliant engineer Cornelis Lely. To prevent further accidents, he recommended to found an academy for geophysical science. This led to the opening of the Academy and Laboratory for Geomechanical Studies at the Technical University in Delft in 1934. This laboratory and academy made some exceptional contributions to the field of geophysics and geo-hydrodynamics, and of course, the Dutch engineers were the first to use them in practice.

What the hell were the engineers thinking of when they made this pretending-to-be-a-roundabout-but-putting-eight-million-traffic-lights-and-causing-terrible-traffic-and-death-and-hatred thing? It backs up onto the highway because people can't merge into that traffic, and requires people to cut each other off on the right hand side if they don't want to get shoved back onto the highway.

Engineers had some crazy dreams back when volumes were projected to be a third of what they are now. They figured the infrastructure would all be completely replaced when its lifespan was up, anyway, instead of patched and ignored for decades.

It's even worse than that because the entire first photo is to the right of the hedgerow in the center of the road. What the photo is really showing is just that they ripped out the buckled lanes of the road and put in fill and gravel.

It backs up onto the highway because people can't merge into that traffic, and requires people to cut each other off on the right hand side if they don't want to get shoved back onto the highway. Building the Masspike extension was a very controversial and problematic endeavor. You have to remember that they were basically building on top of already existing railway corridor right of way (some of which still exists!) and there were already limitations based on existing roadways and properties. There was also a hotel they had to build underneath, too. Even then, without the terror of the south side Washington street, the traffic would be even worse.

Cichlidae, I was wondering what your input would be on the current LBJ-635 project that is about to kick off construction in the Dallas area. There's a stretch of 635 that's pretty tough to drive through no matter what time of day it is. Lots of car volumes with older exits and a frontage road that randomly stops. The proposal that they are going through looks like it will do the following: Rebuild the main freeway. Add managed toll/HOV lanes. Reconstruct / build frontage roads. Fix the HOV connections between I-635 and I-35 (TOTALLY AWESOME). Some of it seems like a bit overkill though. Rebuild the whole freeway? Traffic is going to be hell through that area until it's done (and they are projecting a 2016 finish, ugh). http://maps.google.com/?ie=UTF8&ll=32.92578,-96.820428&spn=0.005421,0.01193&t=h&z=16 The interchange between I-635 and the Dallas North Tollway needs to be fixed. Speeds on both roads are usually around 65, and taking that tight right hander for the cloverleaf means people will crawl through it and not have enough time to accelerate. Not to mention people will be trying to merge into your lane at 65 because they want to take the following cloverleaf, ugh. http://maps.google.com/?ie=UTF8&t=h&ll=32.908667,-96.897225&spn=0.010845,0.023861&z=15 Junction between I-635 and I-35E. The main problem I have with this interchange is that if you're on the HOV westbound on I-635, you have to bail out of the HOV lane before this area so that you can get over far enough to stay on I-635, as the lanes to head to I-35E southbound break off the left side. Link to the overview PDF that's been provided to the public: http://newlbj.com/documents/I635ManagedLanes-ProjectOverview.pdf And the TxDOT page with the project info: http://www.txdot.gov/project_information/projects/dallas/i635.htm Should I be rooting for this? TxDOT has been doing a few projects with mixed results (putting in a Michigan left and a SPUI), and improving the flow in the I635 would be good. Just seems like they want to pretty much junk the whole corridor and start again.

Just seems like they want to pretty much junk the whole corridor and start again. Given the volumes they're designing for, that's the best option. The fact that they're building a decked freeway with six (!) managed lanes tells you that they're working with some pretty extreme constraints. Frankly, $3.2 billion is pretty cheap for a project like this. I wish I could see the designs for the new interchanges, but I'm sure they'll be built to modern standards. Since it's Texas, that probably means stacks, and I'm definitely on board with that.

I'm kind of curious if requesting a traffic survey would be proper in this scenario. For background, last fall, Austin Community College opened a new campus here in Round Rock, and the campus was almost instantly filled to capacity (somewhere around 5K students). It is, at the moment, the only building on it's stretch of county road 112, and will be for some time from what I hear. The speed limit has been 30, but everyone has been going 40 because CR-112 is really wide, and there's hardly ever anyone on it. Late last month, Round Rock PD started setting up daily speed traps. There now is hardly ever a time in the morning or early afternoon that I don't see someone pulled over getting a ticket (yes tickets, not warnings) for speeding. Would you say that 30MPH is the right speed limit for this stretch of road?. The street view shows the width, but not the quality. It's almost perfectly flat with shoulders the size of the lanes and I just don't get it.
