It is also known as the Crimean Bridge. or the Kerch Strait Crimean Bridge.
The Russians have massive, massive air defenses set up there and they have been successful in taking down missiles and drones probing it on a weekly basis. When the bridge was hit before it was hit with a sea drone. They have barriers and steel netting in the water now.
The other big problem is the distance. Giving long range distance missiles to Ukraine- that can reach the bridge is a crossing of Putin's red line but that red line is being crossed incrementally. The British have given the Ukrainians harpoon missiles which can reach the bridge. And what the Americans have given is not clear. The Americans have missile launch systems that can take both medium and long range missiles and they/we state openly that the Ukrainians have received only medium range missiles that cannot reach the bridge so Vlad needs to chill out. Except little birdies keep saying that they have some long range ones too. Vlad needs to worry about that.
