On October 16th 1995 the Bridge to the Isle of Skye opened.

Prior to the opening of the bridge the main route to Skye was by the ferry between the 2 villages Kyle of Lochalsh and Kyleakin. The ferry service was operated by Caledonian MacBrayne the short route of about 500m took 5min, at peak times there was often queues to use the ferry.

The bridge construction started in 1992 built by the Scottish company Miller, but designed by a German engineering company DYWIDAG Systems International in collaboration with civil engineering firm Arup.

The main bridge is a concrete arch, supported by two piers. This connect Skye to the small island called Eilean Bàn, the rest of the bridge is level across to the mainland. The total distance across is 1.5 miles. The main arch is about 35m high with around 30m clearance for boats on high tide.

Eilean Bàn (White Island) is the small island upon which the main arch of the bridge rests.

The island has a 21m high lighthouse just below the bridge arch. The lighthouse keepers (before automation in the 1960s) stayed in the cottages on the Island. These cottages where then purchased by Gavin Maxwell who is best remembered for is work with otters. Maxwell did many interesting things including writing wildlife books, his most famous is called "The Ring of Bright Water”.

These days the island is a wildlife reserve being managed by the Bright Water Trust. One of the cottages is now the Maxwell museum. This is a reconstruction of Maxwell’s 40ft living room, containing original artefacts, recreated by Virginia Mckenna of the Born Free foundation.

Most people wanted the bridge, but the way in which it was funded was conversional. Rather than the UK government paying for it, the government allowed it to be privately funded. Then granted a licence for the private company to charge tolls. It was said to be the most expensive road bridge in Europe.

This clearly upset many people. Locals on Skye setup a campaign group called SKAT (Skye and Kyle Against Tolls). After years of campaigning, legal challenges and then the setup of the new Scottish parliament in 1999 the leading political parties made it a priority to have the tolls abolished.

On the 21st of December 2004 the bridge was purchased by the Scottish Government and made free to cross.

demigods are a bunch of preteens with adhd who climb a wall of lava for fun over the summer. their sense of danger is very, very skewed

my point is, there should be more instance of demigods doing stupid shit while out in the mortal world (on non-quest instances)

nothing makes me wish i had some variety of acme ray gun blaster more than when someone almost hits me on a pedestrian sidewalk on a motorized scooter/ebike easily doing 15+ mph on their phone/headphones/doesnt move or even be aware of actual people walking on the sidewalk around them. where pedestrians are going to be. where pedestrians are supposed to be.

Old Internet Fridays #13: traffic-simulation.de

traffic-simulation.de

What’s this?

What’s this website?

A traffic simulation app, built off the MovSim vehicle simulator. The simulation runs a loop of traffic and an on-ramp. Users can adjust the behavior of the cars to see the effect on traffic.

Okay, how did you find it?

I was recommended the podcast The Big Dig recently, about the madly ambitious Boston highway tunnel project that completed the interstate highway system. Highly recommend, by the way -- great storytelling, lots of firsthand interviews and primary sources, and a real focus on the activism surrounding the project.

So as a result, I was looking for some infrastructure-type stuff today. At first I tried www.highwaytunnels.com -- did you know you can claim that as a domain name? Nothing there in any case. Then after a few dense scientific studies and even denser regulatory pages, I hit on simply putting "traffic simulation" into DuckDuckGo and here we are.

How’s it doing on Internet Archive?

Doing awesome at 539 saves. I checked out the 2003 version of the page, incredibly charming:

What delighted you the most?

Fiddling around with the little behavior bars, evidently! What chuffed me the most was seeing the two extremes of "politeness" in the lane-change options. Very rude drivers fuck up traffic flow immediately with aggressive lane-changing:

But overly polite drivers REALLY start to mess things up over time on the on-ramp:

Insightful stuff, and let's be honest? just plain fun. Highly encourage clicking that link to check this out.

I've been overbooking the odd little science-adjacent sites lately. Promise I'll get you some weird art next week ;)

The return of sub-lethal summer temps means biking to drop off some salmon (frozen, on sale at my store) turned into a quick breakfast burrito and mint tea at the park before riding back.

I'm still learning how to efficiently use the gears on my bike, so the super high heats were putting me off doing too much outside with it. I still don't feel super conditioned to the type of exercise that biking is, so I'm still leaving it for days with (for me) tolerable weather. Like, I just don't want to be too gassed to bike back if I go out, because pushing a bike is far more annoying than just walking home or being able to hop on a trolley (busses and trains accommodate bikes, here; trolleys don't really accommodate much aside from [mostly] able bodied people).

There's a couple of more active/main roads and the route I took today was flatter, slightly more indirect, but it was my first time trying out that road on the bike.

Still a little more chaotic than I'd like, but I didn't feel unable to do it. So that's a huge step towards biking around more regularly.

One thing that's majorly aggravating, though, is that road is a trolley street. The bike lane is between the parked cars and the trolley tracks. This is the city of double parkers. So I had one spot where I had to choose to pause, go into the street, or try to slide between a double parked minivan and the parked cars. I chose the last option because there was traffic going both directions and I didn't feel like waiting. Lucky for me the asshole was doubled on an empty spot (minor defense: it was maybe technically *just* too short for his van), so it worked out. Still annoying.

All that said, I really do like biking, and I can't wait for fall and to maybe get some time riding with play friend.

On June 26th 1970 The Kingston Bridge, carrying the M8 motorway over the River Clyde in Glasgow opened.

It might not have the global fame of San Francisco’s Golden Gate Bridge, the impressive backdrop of Sydney’s Harbour Bridge or the history of London’s Tower Bridgee, but Glasgow’s bustling Kingston Bridge, which celebrates its 54th birthday today, is every bit as iconic It was officially opened on June 26th, 1970, by the Queen Mother.

The 52,000-ton structure took three years to build and cost about £11million – the equivalent of more than £180million today. When construction began in May 1967, it was the most expensive road project yet undertaken in Glasgow.

The bridge opening marked a massive reduction of traffic travelling through Glasgow, city centre numbers dropped by a massive 75%!

The Kingston Bridge is 270m long, over 40m wide and crosses the River Clyde at a maximum height of almost 20m.

Today, the bridge carries over 150,000 vehicles a day and is one of the busiest road bridges in Europe. Currently there are moves to have the bridge listed as a structure of historic and architectural interest.

Night bus through Old Street

[twiggybeing]

The 401 highway in Canada has the most traffic out of any road or highway in all of north America.

Because of this traffic, the average speed can drop to a stand still.

If Canada had high speed rail that took a similar route, it would be abled to transport people from different cities to Toronto's city center over 4 times faster.

The amount of cars this would take off the road would significantly reduce traffic, which would also make driving safer and faster.

The amount of time it takes to drive from Toronto to Vancouver with little to no traffic would be 41 hours of driving. If there was a cross country high speed railway that time could be cut down to less than 10 hours using the fastest German trains.

The upkeep costs for rail compared to that of highways are also much lower, and with bringing less cars into a city, it would need less subsidized parking lots which don't pay real estate tax, nor do they make room for businesses or housing.

While I don't fully agree with the all of the whole FuckCars movement's positions I have to admit that they have really made me question and reconsider my political views. For example, I used to think the voting age should be 18 because minors are less capable of forming opinions based on nuanced thought, but after learning that "It's not fair that I have to look both ways before crossing the street, the government should just make cars illegal!" is a position that will not get you laughed out of the room in certain circles, I realized that yeah actually you could probably lower it to 3 and it would make zero difference to the quality of political discourse
