Big grain silos are not recognised by construction offices

[gwahazar]

There are 3 grain silos with rail tracks, and 3 similar one without track, ableit the latter ones also can't be constructed in realistic mode when using road CO - no path found.

I found the issue: some road entry leading to silo points are not valid for construction offices.
So it is not a problem with tracks, both track and trackless silos can be built, but not all roads are working properly.

There are one-way entrances / exits, like a gas station for a one-way road. Therefore, for construction, it is necessary to connect both the entrance and exit to the roads.

Thanks for your reply, indeed I overlooked arrow shaped road entries.
BTW, therefore I have suggestion - all one-way buildings should have one-way blue sign on their menu icons (like fuel stations), to avoid confusions.
