Congratulations))
Can someone help with the construction of a 6-lane tunnel that would pass under the road. is it possible and how?


I'm not sure if this topic is appropriate for such a question, if I put it in the wrong place, then I ask the moderators to move it to the appropriate branch, because I did not find a suitable topic. 
sorry again))

I believe here is fine for it, but in the long run (if it is possible at all), I'll bet this turns into a NAM question. If so, we can easily move it over to their forum.

    I created a 6 lane highway with NAM 49 can i build a tunnel under another road or is it not possible at all?
    I was looking for a suitable entrance to the tunnel for 6 polices, but it is not in the roads submenu.

    I'm guessing still no, but I'm not at all a NAM expert. I installed it for the SAM streets and I've not learned all the fancy other stuff. *:blush: 

    We'll just have to hold tight until the experts arrive to let us know. *;)

    I want to build a ring with 6 lanes and connect 6 highway lines to it, how to do it with NAM 49 elements? 
    I searched a lot on the Internet, but I can't find a video instruction, there is only a description, but it's not very clear for me as a newbie, maybe someone knows a link to a video where it's all shown?

    Currently, the RHW from NAM does not support functional tunnels. 

    See here for a similar topic from 10 years ago: 

     

    Also, while the NAM DLL is still in testing and can support the addition of tunnel networks like Street Tunnels, there currently exists no artwork for RHW tunnels and those would need to be created in order to work.  See more here:

    However, you can use a Maxis Ground Highway as a tunnel.  You can draw the tunnel as a Maxis Ground Highway and then connect it to the rest of your RHW.  It will functionally work as a highway inside a tunnel, but it might look slightly different.  If you use the Maxis Highway Override feature of the NAM, it will look very closely like the RHW.

    I feel this is closely related to the 6-lane tunnel question so I've merged it into this topic. (I believe a separate topic is unneeded this time.)

    And both will need a NAM solution if and when there is one so I also moved the topic to the NAM forum.

    Good luck. *:)

    and will I be able to build a bridge for 6 stripes???
    For some reason, I can't throw two parts of the 6-lane highway across the river. on the opposite side, they don't look like they did at the beginning, it's kind of strange, maybe I'm doing something wrong???

    You should read the official NAM documentation.  Most of your questions will be answered there.  For bridges, see here:

    https://www.sc4nam.com/docs/feature-guides/realhighway-mod/#bridges

    In most cases, you need to build the bridge using the Maxis Ground or Elevated Highway, and then in the option to select the bridge type you can see the NAM RHW bridges as options, including 6S options.  From the linked doc:

    Quote

    The NAM does include bridges for various RealHighway networks. However, it is worth noting that there are some special caveats, due to a hardcoded restriction in the game’s terrain engine, which prevents bridges from being built without at least a one-tile separation between them:

    • Bridges involving the wider S-type networks (RHW-8S and RHW-10S) must be built with the Maxis Ground Highway tool instead of the RealHighway tool.
    • Bridges involving the wider C-type networks (RHW-6C and RHW-8C) are not possible.
    • There are bridges available for adjacent RHW-4 and RHW-6S situations, also built with the Maxis Ground Highway tool.
    • Bridges for RealHighway networks with separate carriageways (i.e. the MIS Ramps, RHW-4, RHW-6S, RHW-8S, RHW-10S, and DDRHW-4) will have their traffic flow determined by the way in which the base network is dragged. Take note of the preview models to ensure you have built the bridge in the correct direction.

    As for building overpasses and tutorials on that, there are youtube videos as well as some other threads here that show how to do it.

    Вам слід прочитати офіційну документацію NAM. Там буде дана відповідь на більшість ваших запитань. Для мостів дивіться тут:

    https://www.sc4nam.com/docs/feature-guides/realhighway-mod/#bridges

    У більшості випадків вам потрібно побудувати міст за допомогою Maxis Ground або Elevated Highway, а потім у варіанті вибору типу мосту ви можете побачити мости NAM RHW як варіанти, включаючи варіанти 6S. З пов'язаного док:

    Що стосується будівництва естакад та навчальних посібників з цього, тут є відео на YouTube, а також деякі інші теми, які показують, як це зробити.

    thanks for the explanation))

    I also wanted to ask if I can use the Wide Radius Curves elements to build large 6-lane rings to be able to connect a 6-lane highway to them?

    If you mean roundabouts, yes, it's possible, but it's significantly easier if you do it with OWR-2 (the typical one-way road) than with OWR-3 (a variant of one-way road with 3 lanes that's included with the NAM. Probably your best option is to experiment first in an empty city, and then build your definitive project when you feel more confident about how to do it.

    Якщо ви маєте на увазі кільцеві розв'язки, так, це можливо, але значно простіше, якщо ви зробите це з OWR-2 (типова одностороння дорога), ніж з OWR-3 (варіант односторонньої дороги з 3 смугами, який входить до NAM. Ймовірно, ваш найкращий варіант - спочатку поекспериментувати в порожньому місті, а потім побудувати свій остаточний проект, коли ви відчуєте себе більш впевненими в тому, як це зробити.

    thanks for the advice))

    I'm trying in vain, but so far nothing works.

    it's a pity that they are not provided in the finished form.

    One option you can use is the Real Expressway OWR-based ramp interfaces, especially those featuring OWR-3 in their mix. You can build much larger roundabouts by carefully connecting those, and probably with more credible geometry than the really sharp turns of the Avenue-based roundabouts.

    Are you asking about highway interchanges?  I found these pictures here a while back and saved them for reference:

    Cloverleaf1.jpeg.dd9ad9d9bd71aba1ae335d495c914983.jpeg

    Cloverleaf2.jpeg.31c3a035ef2108065ac0d2de80ad49f5.jpeg

    I'd suggest searching around in the forums here for examples on how to build.  Those pictures above helped me out a lot when I started building Highway interchanges because at the end of the day it's a bit like putting together a puzzle. With time you'll get used to it.

    Одним з варіантів, який ви можете скористатися, є інтерфейси рампи Real Expressway на основі OWR, особливо ті, що містять OWR-3 у своєму міксі. Ви можете побудувати набагато більші кільцеві розв'язки, обережно з'єднавши їх, і, ймовірно, з більш достовірною геометрією, ніж дійсно різкі повороти кільцевих розв'язок на авеню.

    thanks for the tip))

    how about seeing what it looks like and what it consists of, maybe you have a link?

    Ви питаєте про розв'язки на шосе? Я знайшов ці фотографії тут деякий час тому і зберіг їх для довідки:

    Я б запропонував шукати на форумах тут приклади того, як будувати. Ці фотографії вище дуже допомогли мені, коли я почав будувати розв'язки шосе, тому що в кінці дня це трохи схоже на складання головоломки. З часом ти звикаєш до цього.

    the number of puzzles is simply amazing))

    they are cool but too big in area, I would like something similar to Turbo rings but larger in diameter and with the ability to connect from 4 sides of the highway so that they can be placed where major highways intersect?

    @DreamMachineMan Prepared here a few examples of roundabout designs doable with the RealExpressway (REW) pieces!     :8)

     

    To begin, these are the REW FLEX ramp pieces, the A1 and B1 pieces also support OWR-1 overrides, all the others are for OWR-2 or OWR-3. Meanwhile, the Road / OWR-1 splitter FLEX pieces are currently limited to Road support, these work similar to the drag patterns for RHW-2 branching off as two MIS ramps in opposite directions.

    pkMEOgS.jpeg

     

     

    You can use the OWR-3 ramps to build larger and smoother interchanges that support the surface road networks featuring 3 through lanes per direction. Here I'm showing an example featuring RD-6, twin OWR-3s, TLA-7 and AVE-6. You can replace the 3x3 90° curves with short diagonals or with 2x2 90° curves if you want a more compact footprint. Make sure to provide enough space to transition OWR-3 to the other NWM variants, those use drag patterns. You can also swap the E1 OWR-3 ramps for B2 OWR-3 ramps if you want 2-lane channelized outer turns.

    zyK3yLK.jpeg

     

    Or, if you also use the ramps for OWR-2 as the mainline (A1, B1, D1, E1), you can also hook up AVE-4, TLA-5, RD-4 or twin OWR-2s. This one shows the smaller footprint, but do mind the tight override situation for the OWR-1 crossing in the middle.

    EiQ0UQA.jpeg

     

    If you want something bigger, you can also use the D2 and E2 ramps, which allow for large roundabouts using smooth curves and some diagonal connection support:

    lP7PHVM.jpeg

     

     

    It's also possible to use these pieces to build fully-fledged roundabout interchanges with RealHighway of nearly all the supported multilane widths. Depending on the ramp connections you want, change the REW FLEX ramps as needed.

    I29MR11.jpeg

     

    02RgyYe.jpeg

     

     

    Or you can do roundabout interchanges with a crossroad avenue, either with a large size / smoother geometry, or a smaller size with tighter geometry:

    LgSAEur.jpeg

     

    The smaller version relies on the automatic A1 and B1 ramps formed with two OWR-2s crossing at diagonal T angles:

    hMBlO0D.jpeg

     

     

    And, finally, make sure you know your drag patterns for the OWR curves! These are for 45° turns:

    qBgoaLA.jpeg

     

    These are for 90° turns. Your relevant options will be A, B and C. The other three (D, E, F) work for Road:

    ZpJVlgW.jpeg

     

     

    Really hope this helps you and any other player who checks these out!!     :yes:

    @DreamMachineManЗдесь подготовлены несколько примеров круговых конструкций, которые могут быть выполнимы с помощью частей RealExpressway (REW)!:8)

     

    Для начала, это части рампы REW FLEX, части A1 и B1 также поддерживают переопределения OWR-1, все остальные для OWR-2 или OWR-3. Между тем, части сплиттера Road /OWR-1 FLEX в настоящее время ограничены опорой Road, они работают аналогично шаблонам сопротивления для RHW-2, ветвясь как две пандусы MIS в противоположных направлениях.

    pkMEOgS.jpeg

     

     

    Вы можете использовать пандусы OWR-3 для строительства больших и более плавных развязки, которые поддерживают наземные дорожные сети с 3 сквозными полосами в направлении. Здесь я показываю пример с RD-6, двумя OWR-3, TLA-7 и AVE-6. Вы можете заменить кривые 3x3 90° короткими диагоналями или кривыми 2x2 90°, если хотите более компактный след. Убедитесь, что вы предоставили достаточно места для перехода OWR-3 к другим вариантам NWM, которые используют шаблоны перетаскивания. Вы также можете заменить пандусы E1 OWR-3 на пандусы B2 OWR-3, если хотите 2-полосные канализированные внешние повороты.

    zyK3yLK.jpeg

     

    Или, если вы также используете пандусы для OWR-2 в качестве магистрали (A1, B1, D1, E1), вы также можете подключить AVE-4, TLA-5, RD-4 или двойные OWR-2. Этот показывает меньший след, но не обращайте внимания на жесткую ситуацию переопределения для пересечения OWR-1 посередине.

    EiQ0UQA.jpeg

     

    Если вы хотите что-то большее, вы также можете использовать пандусы D2 и E2, которые позволяют использовать большие кольцевые развязки с плавными кривыми и некоторой поддержкой диагонального соединения:

    lP7PHVM.jpeg

     

     

    Также можно использовать эти части для строительства полноценных развязки с RealHighway почти всех поддерживаемых многополосных ширин. В зависимости от нужных пандусных соединений, меняйте пандусы REW FLEX по мере необходимости.

    I29MR11.jpeg

     

    02RgyYe.jpeg

     

     

    Или вы можете сделать кольцевые развязки с перекрестком, либо с большим размером / более гладкой геометрией, либо меньшим размером с более плотной геометрией:

    LgSAEur.jpeg

     

    Меньшая версия опирается на автоматические пандусы A1 и B1, сформированные двумя OWR-2, пересекающиеся под диагональными T-образными углами:

    hMBlO0D.jpeg

     

     

    И, наконец, убедитесь, что вы знаете свои шаблоны перетаскивания для кривых OWR! Это для поворотов на 45°:

    qBgoaLA.jpeg

     

    Это для поворотов на 90°. Ваши соответствующие варианты будут A, B и C. Остальные три (D, E, F) работают на Road:

    ZpJVlgW.jpeg

     

     

    Очень надеюсь, что это поможет вам и любому другому игроку, который это проверяет!!:yes:

    Thank you very much for your help))

    I will try to implement it. maybe I will experiment with one-way streets.
     

    It's a pity that all these solutions were not implemented in the game to simply install at once. I hope that in time we will be able to get something similar

    By way of a "Thank You" gift, we'd like to send you our STEX Collector's DVD. It's some of the best buildings, lots, maps and mods collected for you over the years. Check out the STEX Collections for more info.

    Each donation helps keep Simtropolis online, open and free!
