@CRneu 4 ай бұрын

Yup. Then add in safety requirements so nobody dies putting up a bridge, and you kind of start to understand why projects like these take so much time+money in developed countries. You could build this in half the time but it wouldn't be nearly as reliable nor as safe to build. It would cost lives during construction and then lives when it eventually fails before it was supposed to. Talk garbage all you want about how american projects go over budget and take forever, but we don't have routine failures like countries that don't build things properly/safely. The success is measured in preventable deaths.

I have been involved in creating that paperwork. That book is a set of drawings used to construct the road and bridges. We drew them by hand using pencil and paper. And then printing sets of copies of blueprints on 36 in by 24 in paper. Later in my career, we went to computer aided drafting systems (Cad). We started printing on 11 in by 17 in paper. By the end of my career we just sent the drawings as electronic files to a printer that distributed them as PDF format electronic files to the contractors for bidding and eventually for the winning bidder, to construct the project. I suspect that by now, the use of tablets and laptops is replacing those books of paperwork in the field.

When you get outside of most major cities in California, you come upon very well-maintained low traffic roads. It's where a lot of our gas tax goes since repairs within a city are much more expensive and time consuming. There are some really beautiful places in California when you get out of the major metro areas like North of LA along Pacific Coast Highway, or South of Reno hugging the Nevada/California border. For a road trip, I don't recommend using North 5 to get to Northern CA. It's basically a straight shot through the central valley for hours when you are North of LA.

I mean, maybe if you put enough traffic calming/ downsizing on the old routes? Looks like a great chance to get traffic out of neighborhoods. Generally how far people travel isn't a question of distance, it's a question of time per trip, so a new Highway means more trips made and in a few years the old roads could be back to current travic levels. But this is a great opportunity to block (or at least inconvenience) through traffic downtown to improve noise levels and increase safety.

@@thatcapuchin6597 yeah it would be tough, but here’s where other people might disagree with me: i don’t think those roads should even be highways. they should be vibrant, walkable commercial and residential corridors. maybe they could terminate 178 at the interchange with golden state ave as a means to connect to 99-S and then 58-W via the new flyover. it would be super roundabout and the car-brained people of bakersfield would oppose it, but we would then have a wayyy better and less disjointed downtown and a safer rosedale highway. of course rosedale and 23rd/24th street could be kept for local travel, but all cross-town/regional travel would be routed through 58/99/178. it’s a total pipe dream and might not even work logistically but i’m just spitballing. i also think they should cap 178 and return the old urban grid of east bakersfield, but that’s a whole other can of worms.

Rob, you do a wonderful job of concisely explaining complex engineering!!! Many box-beam girder bridges today are being built (35W replacement bridge in Minneapolis) using precast segments and use the same principles as the cast in place type you have shown (post-tensioning). The superelevations you noted on this project wouldn't allow for the precast type of construction. FYI, the foundations shown for the bridge piers are called 'drilled shafts.' One minor correction: The top of the piers on this bridge are called 'pier caps' and not 'bent caps.' A bent cap is normally used to tie together a group of 'bent' pile columns. Interestingly, box beam design is what saved the I-10 bridge in L.A. from needing a complete rebuild after the fire was set underneath in November. Had it been steel girders it would have collapsed like the bridge in Philly last year. Instead, they were able to use shoring (falsework) to support it and get traffic back on it while repairs are made to the damaged components.

What America does instead is patchwork repair our infrastructure because it only costs 1/10th per patch to do vs building something new that wouldn't require patchwork.

I’d love to see a video on how MN DOT is spending $350 million redoing the “can of worms” interchange on I-35 and I-535 in Duluth Minnesota. Back when it was built they elevated it off the ground using steal beams or shallow piles. Overtime they’re starting to rot and rust away and the interstate goes directly above it. Another fun fact of why they’re redoing it is because of all the home homeless people that live under it. It would be awesome to see a video on it at some point!! Love your videos Rob! Love from Duluth Minnesota. Edit it would also be awesome to see a video on the construction of the new Blatnik bridge connecting Duluth Minnesota to Superior Wisconsin it’ll be a video do in the future though as it’s still in the planning phase

I've also been curious as to what goes into building a bridge deck, so this was quite informative.

@seanrodgers1839 4 ай бұрын

Fascinating, Rob. I've been seeing a lot of factory built concrete beams used for overpasses here. Also some uniquely interesting structures in some locations. I believe that they don't want more steel, because winter salt rusts it. A big thing here now is moving bridges for fast replacement

My hometown! HWY 58 extension west was cancelled west of the 99 in the 1970s but decades later the city realized we needed a crosstown freeway. Hindsight really is 20/20

Found this out as a teen by looking up at the bridges and seeing a wood grain pattern and perfect 4x8 foot lines. I figured they were hollow to some extent

This was a really good video! A bit more technical than your previous videos, which I enjoyed. It is fascinating seeing the purpose behind all the different design elements of the freeways that I drive on daily.

Nice work! As a bridge engineer, i think you did a great job explaining how bridges are made! Of course theres a lot of other nuances that go into it but overall i think you did a great job! I haven't seen the hollow concrete girders used in my state yet but we use precast I- beams for a lot of our bridges without the slab on the bottom. The most similar thing i can think of that we used was a steel tub girder bridge but each tub was visible. Can't wait to see more from you

FINALLY DID ONE ON BAKO! Knew it from the intro. This is the 58-W. For years, Bakersfield had 99 N and 99 S but only one way going east/west. 58 E is the only highway, 58 W was just a bunch of avenues you followed. Now we have the Westside Parkway, which is the Western highway of the 58, which is now finally connected via this project, known as Centennial Corridor.

My favorite part is recognizing the exact areas Rob goes to (I recognized that part of Medford- it’s near some shopping areas and a park, where there is the older overpass like that). Good to see they are expanding to get Bakersfield connected to I5 (slowly, but surely).

Glad to see you had a pit stop in Farmington. Hope you do an episode on that new highway from Farmington to Syracuse. The West Davis Corridor is a great road and a blessing to those of us in West Davis County.

This has helped me understand what my city akron ohio is doing with our 5 year redesign development of what we call the innnerbelt. Connecting local route 8 and interstates 77 and 76. Because I've seen the cement pylons being erected and the plywood overhead as i go underneath. Thank you

I love your videos! I’m a massive road geek and love learning more about roads and freeways. I wish they would just make CA-58 into I-40 all the way to the I-5… It just makes sense… There’s plenty of traffic on it for it to be a interstate…

I didn't know Caltrans was working on extending I-40 into Bakersfield, but now all that improvement and the new overpass at Kramer Junction makes sense. Learned a bunch of new things from this video, thanks Rob!

This video answers so many questions I’ve had about bridges for so long. I know your in Cali, but i wish a Texas version of you could do this same video to show how they do the Texas bridges. I know we use I-Beams made out of pre-stressed concrete, but they also add these pre made tiles to the bridge before they lay the deck. I’d love to see that up close and detailed one day.

I can't believe I missed a new Rob video ... for TWO MONTHS. This was the fix that my mental health was asking for. Thanks for being awesome, Rob. On a totally separate note, you remind me of Rob Wolchek who did the Hall of Shame on FOX2 in Detroit. He was super popular way back when ... maybe still is, I dunno because I don't follow the news but like you, he did cool segments that people loved. ❤

I went through that interchange today going from Ridgecrest/Death Valley back to SF! Was checking the map and so happy to see that they finished the connection for the 58! And I guess the section you were on is the last section that's still not open yet. Add: and glad to see that things are still getting built here in California... And yes, the traffic cops were out in force.😂😂😂
