When you forget to play the game... 😅

This was fun to watch, wouldn't mind having a few more like it.

Have you ever broken down the Texas Stack interchanges? SUPER TALL flyover bridges and tons of lanes with a speed consistent with highway speeds on the exit lanes.

My favorite is the intersection between I-10, 620 loop, and highway 290 in Houston. 29°46'50.1"N 95°27'13.8"W
Massive

For the record. The first bridge in Canada was built with no countermeasures to prevent ice buildup on the wires. So we had ice bombs falling on ppl’s cars the first year it was done

Had to stop and count the wheels on the double-trailer that RCE commented on.  You see 11 rims, which means a minimum of 22 wheels... however trailers like that often have double-wheels on the back ones to deal with all the weight they're hauling but never the very front set because that would interfere with steering.  That means it could be as many as 42 wheels on that vehicle.

yeah, in the USA and Canada, those "hatchings" are called "singing medians" and were common in the 1950s and 1960s, becuase they'd make a noisy vibration if you were to drive over them.  the idea is that they'd be placed in the central reservation of an avenue or boulevard of a busy road to prevent people from driving across into the other lanes of traffic, though it could still allow people access to and from driveways of houses or businesses.  Obviously they're no longer up to standard, though you can still see them here and there on older roads that don't really need reconstruction (like Essex County Road 20 in La Salle, Ontario, or Robertson Road, the old routing of Highway 15, in Bell's Corners, near Ottawa, Ontario)...  As for that giant truck with all the wheels.. that's an articulated dump truck.. great for hauling gravel, stone, broken-up concrete... my father used to drive those.  He looked empty, but they can haul up to 100,000 kg (about 100 tons)!

The painted lines on the hatchings are called "gore markings" because they're at angles to the lanes.  I agree with you that the ones at Portage Lake Bridge are reversed, but likely pre-date 1971, when the version of the Manual for Uniform Traffic Control Devices (the road markings and signs standard the USA, Canada and a few others use) was published, specifying gore paint colours (yellow/black) and that two-way traffic lanes should be separated by a yellow line, not white anymore, and that hatchings should ideally have a colour on them in high-traffic areas.  Ideally, the gore markings would try to lead your eyes AWAY from an obstacle like a bridge pillar, or a widening/narrowing of a road from a single-carriageway to dual-carriageway, or an off-ramp so you don't thread the needle and end up stuck between them.  The longitudinal grooves at the US 41 hamburger-ish roundabout seem to be there for vibration/noise to alert the drive to stop IMMEDIATELY!, as well as to help with the flow of rainwater, since it is on a hill and the upper peninsula of michigan gets a good amount of rain at times.

Had the hamburger-ish roundabout been designed today, there would be the stop signs WITH flashing yellow lights, possibly with a yellow sign with black text that says "GIVE WAY TO CROSS TRAFFIC" or "WAIT UNTIL CLEAR", with the idea that the blinking light would be extra-visible at night or if there's fog.  There is a saving grace here: both streets that connect to this are a one-way pair, vastly reducing the numbre of movement possibilities!  I doubt there's really a need for a traffic light (and if one was installed, there would need to be two, to serve that one-way street below and prevent back-ups)...  with the hill, Veterans Memorial Park at the top of said hill, and the lake adding geographic constraints, this appears to be close to the best of a tricky situation in regards to traffic management.

As for the first bridge, that's the Trans-Canada Highway (BC Highway 1) in North Vancouver, British Columbia.  That's an express-collector (or collector-distributor) setup with four carriageways.  That's nowhere CLOSE to the maximum number of lanes for that type of freeway-in-a-freeway, though... check out the original that did it, Interstate 94 (Dan Ryan Expressway, built in the early 1960s) In Chicago, or Interstate 96 (late 1960s) Detroit, or Highway 401 at any point between Milton, Ontario and Oshawa, Ontario in the Greater Toronto Area... Highway 401 has EIGHTEEN LANES in a 4x5x5x4 configuration throughout most of it!  And yet it's always gridlocked anyway, go figure...

For the last interchange, That's where Florida's Turnpike (Florid Highway 91 but NEVER signed as such!) meets Interstate 95 and a couple other state routes... near Miami, Florida those two lanes that go high above everyone else are High Occupancy Toll (HOT, basically carpool) lanes, designed to ferry cars, vans and so on full of people over and around everyone else, if they're fine with paying a few extra dollars to avoid any traffic slow-downs.  They're becoming quite common on otherwise toll-free interstates as of late, and are getting popular.  The only real alternative to the dedicated bridges for the HOT lanes would be to widen Interstate 95 and shove them on the inside of THAT.  Florida Department of Transportation likely had the room, but saw the eye-watering costs of having to widen or replace all those bridges, and thought "screw it, it's cheaper to just do it this way" instead. The tall HOT flyover isn't even the tallest overpass i've seen.  Check otu the ones in Houston or Dallas in texas if you want some truly insane, huge and TALL five or six-level interchanges.  They really do build things bigger in the lone star state!

Why no, i'm not an engineer, just a guy that has spent WAY too much time in traffic, and WAY too much time in SimCity 4 Deluxe plotting out ways to fix said traffic :P

The etched in lines are often called rumble strips. they are to assist drivers in maintaining lane position in snowy conditions. great video idea

Can we take a second to appreciate how detailed and advanced that 3D Google Maps or Earth view is? He can zoom in so far, get a perfect image of roads and buildings, and rotate it around in a 3D plane super smoothly. I know we take this stuff for granted now, but it amazes me how high fidelity that 3D map is with how far he's zoomed in. Technology is amazing.

the etchings in the hatches are intentional they're cut into the road with a big saw to create sections of road that are rough enough to vibrate and alert drivers that they are outside their lane, even potentially waking drivers who've fallen asleep

12:54 The Yooper Loop is one of the most frustrating pieces of road and very difficult for non-locals to navigate. There are even shirts available saying “I Survived the Yooper Loop” 😂
Love this interchange review video! Keep them coming.

Some knowledge from a corner carver:

The hatching being goofy in Michigan might be angled for drainage and snow removal too. I grew up in CT, rumble strips on the side of the highway can collect water and catch plow blades leading to icy potholes that spin you out or suck you into the ditch. It's really just a texture to make noise and alert anyone falling asleep or not paying attention. For those same 2 reasons, reflectors are set into the road surface so plows don't catch them, whereas in CA there are often no zizzies and reflectors are mounted on top to make noise (saves time on road construction over long stretches as well). Rumble strips also catch a lot of the junk that can appear at the side of the road (broken parts, debris, etc) and have been used in intersections to allow a place for that stuff to collect so it doesn't get run over.

For the line on the wrong side.. those line are groove that make you car vibrite and huge sound in case you fall a sleep or on your cellphone to wake you up like... HEY WAKE UP YOU GOING OUT YOUR LINE.

The more you know :)

8:05 I don't think Matt knows how arrows work

That last interchange with the huge viaduct over everything is just an express pay lane for only north/south. So over the top and it still backs up!

Based purely on the reaction to the first highway, Matt really should never look at the 401 through Toronto.

As a Michigander I can tell you, nobody even pays attention to lines in the road. It's soo bad. People are so bad at roundabouts here it's insane. I take two to work and every day I say "What are you doing?!?!" at least once. haha I'd love to see how smoothly traffic in other countries operates.

2:15 - The reason there is 4 highways is because in Canada it is very common on our busiest highways to have both an express and collectors highway (so its 2 highways each way). The express has specific merge points every few exits and are intended for people who will be on the highway for a long period of time so they're less bothered by merging traffic, where as the collectors side is always connected to the exits and slowed down/impeded by by incoming and outgoing traffic.

The first city is Vancouver area.  There's a lot of rivers, so putting different highways together over the same bridge was more efficient.

"Look how many lanes there are!"
Car-centric North America be like: "Oh really."

Greetings from Vancouver, Canada! Happy to see RCE do a bridge review on a bridge I drive on all the time!
