If you stuck it on a normal flatbed trailer (assuming they make normal flatbed trailers that long), it might end up being too tall for clearance restrictions. Well these flatbeds might not be exactly normal, but they seem common enough and capable of carrying a 40m / 130 ft bridge beam through city streets and under bridges with a fair degree of control. But clearly the other method works well enough that it isn't constantly in the news, so it must be relatively safe: https://www.youtube.com/watch?v=TCOfY5v64fQ https://www.youtube.com/watch?v=DD01WOjmmIQ Kaal fucked around with this message at 18:10 on Sep 25, 2014 |

Anyone interested in the I-84 project should be glad to hear that we've already gone through a couple dozen alternatives. Hopefully the DOT approves our draft Needs and Deficiencies report soon so I can give you guys some more details (and pictures!) Edit: For anyone who can read German, spiegel.de had a good article today on how one town removed all traffic control devices - including signals. http://www.spiegel.de/auto/fahrkultur/verkehr-ohne-schilder-und-regeln-shared-space-in-bohmte-a-993212.html Cichlidae fucked around with this message at 21:23 on Sep 29, 2014 |

Well, looks like the East West Link in Melbourne (toll road) might happen. It's been a big issue for a year or two now with many protests but yesterday the government signed contracts to get it built, while we're 60 days from a state election. It will be an election issue because the opposition (who will probably win it) have said they'll tear up the contracts and not build the road ahead of a Metro (train) tunnel. http://www.abc.net.au/news/2014-09-30/east-west-link-cost-to-taxpayers/5778086  Anyway, video render of the two tunnel portals, what a mess of flyovers: https://www.youtube.com/watch?v=PQHBjlnSvdM I'd hate to live in those soon to be isolated buildings too. Google maps of Western portal location: https://www.google.com.au/maps/@-37.7876795,144.9411798,556m/data=!3m1!1e3?hl=en google maps of eastern portal location: https://www.google.com.au/maps/@-37.7961501,144.9944523,524m/data=!3m1!1e3?hl=en It is controversial because most of the councils it runs through don't want it and challenged the government in the supreme court, which an appeal failed and the contract was signed that day. This first stage is $6.8 billion dollars for the 4.4km tunnel & entrances. drunkill fucked around with this message at 16:20 on Sep 30, 2014 |

I guarantee the contracts have penalty clauses making it just as expensive for the government not to build it as to build it. This is really common when elected officials are doing the old reach-around for their donor buddies and don't actually care anything about the project, its goals or intentions, or any poo poo like that. It's all about donations and securing a post government gig.

Oh of course. It will return to the supreme court after the election regardless of the election outcome. Anyway, a few renders: The existing structure (Citylink) is the rightmost carriageway and the sound tunnel. All the ramps are to be built to connect with citylink and also connect with the future stage 2 of the project.  Existing sound tunnel (one of the default windows 7 desktop images actually) on the right, second soundwall to be built around the two new flyovers.  Eastern portal, new flyover for eastbound traffic to turn right bus and bike lane included, currently is is a weird loop on the left of the bridge.

I'm starting to want to be the pain in the rear end that holds a project up for months. Two separate counties are closing their sections of two parallel routes to the same place (ie one county closing a chunk of route A, the other a chunk of route B) and for the month or so they overlap it's going to massively gently caress everything up for anyone who has to travel that way. There is a third route that takes way longer, but they could just hold back the later project for a while until the other one is finished. Fuckers.

Here's the (almost) finished product of that RRFB crossing concept I posted earlier. The bus stops will have concrete pads installed once construction is complete.

About a year ago, they put up a pedestrian crossing visible slightly to the south of here, (South Miami) on a bike trail that crosses a busy four lane undivided roadway, only without the mast arms. Instead, each side of the street got a motion and button-activated gently caress-off bright multi-lamp Pedestrians In Roadway flashing signal, with neon-yellow reflectors all over it, and double stripes of that newish ultra-reflective tape on the road surface. Obligatory separate state law signage, etc, etc: It was REALLY GODAMNED HARD TO MISS. Apparently not hard enough, though. Within three months, both signals had been hit and destroyed by vehicles, and haven't been replaced.  Miami is part of the third world.

Shamelessly stolen from AI: I live nowhere near here, thank god. (Make sure you rotate 180 degrees to see the full horror) How could this be fixed, short of nuking it and starting over? I assume locals avoid it if at all possible, but it still seems like multiple accidents waiting to happen.

(Make sure you rotate 180 degrees to see the full horror) Oh god it's like standing between two mirrors, just fractal intersections repeating in every direction. I'd disconnect either Harding or water street from the intersection and make the other a 2-way street without parking. Or get rid of that nasty gas station and the parking lot south of it and maybe try to build a big roundabout? The area really feels like it was supposed to be a mostly pedestrian square but it's been horribly retrofitted over time to serve cars.

 I always thought these arrows were cute. It's for a 5 way intersection. It couldn't be straight and right, because straight is the wrong way down a one way street. So, it's mostly straight but tending right, and hard right.

It looks like they've done the smart thing and simply removed any signage, forcing drivers to work it out themselves. It's probably unnerving but is honestly safer than creating some kind of rule for drivers to rely upon. Personally I'd just ban cars from that entire intersection, that seems a lot cheaper than buying up all that real estate just to make it car-safe. Oops, it looks like there's a couple of small Keep Right signs. Most of the signage then. Kaal fucked around with this message at 01:39 on Oct 3, 2014 |

I have another "why did they do this" question. North Carolina recently expanded a large portion of NC 211 into a 4 lane highway. Instead of a normal pavement then grass, they installed curb and gutter down almost the entire length of the road. On one side is a 6" barrier curb and in the median is a mountable curb. So if you have a flat, you pretty much can only go into the median. Is there a reason this was done? This is the google maps for reference

There are literally no poor people living in Pinehurst, hence the overbuilt infrastructure. The place is trying to turn into an upscale retirement community ala Naples or The Villages, building up around Pinehurst Resort/Country Club (directly around 211). That's why the mast arms are ornate and the roundabout further down has brick pavers for medians. This road in The Villages is of identical construction style. See the connection? Old rich people don't like puddles on their roads. Varance fucked around with this message at 03:26 on Oct 5, 2014 |

Yeah, I know that's why they don't want to do a bridge system to fix that lovely roundabout that fuckers can't drive on. I was just wondering what the purpose was, but considering it's Pinehurst who made the decision, probably just to keep the rabble off the side of the road, which is stupid as gently caress.

The curb on the right doesn't look like it'd be that difficult to pop since it's rounded, if that's the concern. But yeah, it's done to act as a rain gutter. Maybe it's on a flood plain. Here in Oregon those sorts of roads are really common, particularly in new suburbs, since we get lots of rain. The main difference is that we'll usually install them as part of a bike lane.

Well it looks like they at least built a pair of multi-use paths, which are what Americans build when they think, "Oh let's be considerate for those weird non-car people". It's almost the right idea, except that they need to be put together and made two to three times wider.

Well, it appears there's been an oversight in the design process. As part of the landscaping, palm trees have been planted directly in front of the RRFBs in the median.

We tell them, "stop landscaping the splitter islands, they're not being maintained and they end up a dusty mess." They do it anyway.

Hah, that's clever. I have one area like that in my commute, where I choose which way to go based on the current state of the intersection's traffic light... There's also an area in Amsterdam where there are two ped/bike ferry stations to cross the river, separated by a canal. Near the last bridge that crosses the canal there is a sign saying which ferry will come first, so that you can make sure you are on the correct side of the canal to catch the earliest one. Quite convenient!
