Only if you’re in a car. On a bike, it’s super easy. If you’re going over the lions gate, then your whole commute is on dedicated bike infrastructure, from the spirit trail in North Vancouver, onto the bridge itself (though I wish the shared bike/pedestrian path on the bridge was wider), and then it drops you off straight onto safe bike infrastructure in downtown (you just need to turn right onto Chilco)

The other bridge is also fine, though not as nice. Two blocks before you reach the bridge, the bike lane ends, and the “bike route” is just to take the side street for two blocks, before coming back up and getting onto the bridge. When you enter Vancouver, you’re greeted with okay-ish multi-use pathways for a short while, followed by quiet neighbourhood streets.
