You can edit the profile to ignore ways based on osm id and list the id
on a secondary csv file.

Another approach could be to edit your OSM file. You could identify
the OSM nodes of the collapsed bridge (using openstreetmap.org) and
remove them from the file.

Create a class in your OSM extract for the collapsed bridges. Compile
two different OSRM profiles - one that avoids class 'bridge-collapsed'
and one that doesn't.

Hi Nikhil,
Thanks for the response! I was checking the car.lua and I will
keep looking into it, but I think this would work for a
generalized restriction. But I don't want to exclude all bridges,
I want to exclude some specific ones (detected as collapsed).
Best regards,
Andres

Hi Andres,
Instead of trying to actually remove the bridge data, why not
instruct (your own instance of) OSRM to avoid bridges when
reading the OSM data?
Take a look at
https://github.com/Project-OSRM/osrm-backend/blob/master/profiles/foot.lua
I don't know right now about bridges, but I was able to enable
pedestrian routing over trunk roads by tinkering around in
this file and then building and running OSRM.

Thank you for your response!
I'm still inclining to use OSRM directly. Do you know if
it would be possible to exclude bridges from the analysis
if I use one of the Docker images?
Also, in general, how would I proceed about removing a
bridge? Should I (temporarily) remove it from the road
data? Or could I query it out?
Thanks for the help!!
Best regards,
Andres

Hi Andres,
The public web service doesn't allow for exclusion of
roads/bridges. If you setup your own copy of OSRM you
obviously do have the freedom to exclude anything.
Alternatively you could look into Rural Accessibility
Map. An application on top of OSRM developed for the
Worldbank which is used to calculate the impact of
road improvements on the accessibility of a region.
You can use it to other way around as well: Calculate
the impact of a bridge collapse.

Hi! I'm a PhD student at IUSS Pavia doing research
on the impact of bridge collapse.
I want to use the OSRM public web server to
calculate a duration matrix using the Table
Service. How can I exclude a specific bridge (or
several) from the query?
We use OSM information, so we do have the OSM id
numbers for the bridges we would be excluding.
Thanks for any assistance you can provide.
