Unlike the bridge crossing Lake Sumter, where there is a dedicated walking and biking lane, the Chitty Chatty bridge features(?) a single walking / biking lane on the Rohan side of the bridge which abruptly ends at the top.

While a good idea (developer liability), won't this cause more problems than it attempts to alleviate?

As a walker / runner / cyclist, with many years sharing space with carts and cars, here is my take.

On a flat roadway / sidewalk

1. Walkers travel at 2 to 5 mph.
2. Runners travel at 6 to 10 mph
3. Cyclists travel at 8 to 18 mph
4. Carts travel at 20+ mph

So what happens at the top of the grade when the four groups merge together to travel across the bridge?

Answer, the walkers walk at 5 mph, the runners run at 8 mph, the cyclists cycle at 14 mph and all the carts line up behind them, even though the cart drivers are used to traveling 20 mph.

Hopefully, all the cart drivers will be abundantly patient and slow to 5 mph. The carts will not attempt to pass the walkers / runners / cyclists. Yeah right!

Can you say Morgan and Morgan?

Actually it is worse as the average walker is more like 2-3 mph.
