the bridge whos shared cost could reduce polution and connect both halfs of the globe with an easier way to get around. was thinking the costs could be shared like usa 10% canada 50% and russia 40%
i checked the depths and on the canada side its around 50m depth and on the russian side its 40km deep. 40 km long each side to the center islands

for comparison the bay bridge in San Francisco (deepest in the world 240 meters) 40km long cost 6.5 billion dollars. technology has come along way since and now we have floating bridges also it could be alot smaller only 2 or 3 lanes with a que. so the cost could probably be more like a 2 billion dollars possibly more or less i’ve never built one before.
“the deepest pier in the world is on the Bay Bridge at 242 feet (~74m). This was built in the 1930’s, so does the feat of engineering still remain at the deepest, or has it been superceded?” https://engineering.stackexchange.com/questions/19004/what-is-the-deepest-bridge-pier-in-the-world
might be worth it for lumber shortages alone heh. if either side built a bridge first it would shorten the trip and cost to something more managable for homebuilt ships (air/sea) also providing a way to do it using customs directly.
