Thanks for posting my video, Mike!
I recorded this for TouringPlans, there's a blog about the bridge construction on our website today.
I was surprised too how little time it took, I was walking at a moderate pace and made it in 8 minutes. At an easy jog it would be closer to 5, it's really not much further than the RPR walking path, and maybe less than Portofino's!
Of course the hotel is ginormous, if staying at the south end tack on another 10 minutes of hiking...
