Of course. After all, they built bridges in worse conditions. There is already a project that has passed the Expertise, there are projects of approaches to the bridge (he himself participated in the design), which also passed the Expertise. Although in general it is not indicative, but it can be solved. Yes, the geology is not very good, but we will drive deep piles, and even at an angle. Yes, seismic, but we will provide for seismic protection and seismic isolation. Yes, big ice loads, well, let's strengthen the supports. Yes, let's start the trains and cars at once. And yes, we will raise the navigation aisle higher to allow the passage of large vessels. Such tasks have already been solved more than once.
The bridge will be built. (I am silent about the price of the issue.) In general, this is big politics, which is very offensive, because we have a lot of large construction projects being politicized. Objects are built not because people need it, but then to overcome something and prove something to someone.
Well, I'll tell you a secret: it's already being built :) ____ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ ___ and this is not even a point of view, but a real fact :)
