Oof. As a daily rider, I’m hard pressed to think of something more challenging than riding on the grade of that kind of tunnel. It would be fun biking downhill to the bottom of the riverbed, but the uphill on the back would be like a Tour de France mountain stage! That is one of the engineering challenges - making the grade manageable. The steepest grade in the New York Subway system is 5.5% - anything over 5% is considered very severe and is generally avoided these days. Most cyclists can handle that fine, nowhere near true mountain biking climbs.

Some of these ideas sound like 5-10 year projects. 🤣
