The Intersection misses bridges?

[mattlee1111]

I got 2 problems 

1.I create a interchange,then the 2 lanes become 3 lanes in the intersection.But the bridge disappear in the intersection??

2.in order to solve first problem,I add the bridge in the widening zone,But the bridge deck didn't attach the lane??

Just tried this, works ok for me? I'm on 2017

Thanks for help.I already upgraded infraworks 2017.but the problems still existed...

The 2nd question--->

When I widen a lane in the transition,then Add bridge in the transition,

The bridge won't follow the route in curve zone of the transition

for extreme example

Hello,

Once you select the bridge, select a girder group and set the “Girders in plan” parameter to curved in the Girder Group stack panel.

I think that will resolve the transition issue you are showing. Please let me know if this gets you what you are looking for!

Thanks,

@elliott.rosenfeld shouldn't it be better if the girders will automatically follow the bridge? Is it something that we should request through an idea?

I got the same results when creating a bridge with a curve.

P.S. I cannot find the girders in plan. Are you using the Rolling Sandbox?

Thank you

You can put on Idea station!!

Thank you! Done 😃 Let's hope

I set the “Girders in plan” parameter to curved in the Girder Group,but it still didn't work??

Hey there,

That's too bad, i wasn't expecting that result. Let me check with the bridge team to see if there are any bridge curve limitations built-in. Also, if you are able to share you model with me I would be happy to take a look as well. You can direct message me to share your model.

Thanks,

Elliott

Thanks~

I will send message to you for sharing my model.

I'm new to using Infraworks but I think I might know what your problem is for your 1st pic.  I had the same issue and what I noticed was that you On Ramp is not a bridge.  Try making the On Ramp a bridge for a small section.  I think that because the On Ramp has grading the coding is trying to add the grading to the intersection and that is why your bridge intersection is missing.

I try to change the ramp from a embankment to a bridge ,but it still miss the bridge in the intersection

I think the problem is -->use widening to add a lane ,it will miss the bridge in the widening zone~

Thanks for your advices~

We are aware of issues in modeling bridges at intersections. We will be investigating different possible solutions.

This still seems to be an issue -- using 2018 version. Also to the right of that, is there a way to include the barrier in an intersection? Maybe I knew this once and forgot that skill to learn a new one...?
