Isn’t that the point ?
(assuming it’s clear to enter the roundabout)

Maybe if you are able to bring your car up on 2 wheels....

If properly implemented, roundabouts are great.

In cases where multiple roads meet and volumes are relatively equal in all directions in both traffic volume and speed, they efficiently distribute traffic where it needs to go without the hazard of crossing traffic.

If the traffic is very directional along one axis of travel or the speed of traffic is very different between directions, they don't work as well. I'm thinking of the proposed Manitoba Highway 1/16 roundabout as an example of a potential bad design.

They are hostile to pedestrians because the concept of keeping moving is at direct odds with what pedestrians expect in North America - wait for traffic to stop before crossing. In theory, drivers should yield. Whether they do here is kind of a question of how lucky one feels. They also usually require more crossings to get to a destination as opposed to a square intersection.

A good solution is what was done at Portage and Main. No, it is not a roundabout, but the solution is ingenious.

Traffic lights?

Edit: Misunderstood what you were referring to: pedestrians.

It's expensive though.

Underground walkways. You cannot cross the street on street level.

A-15 : The Gédéon-Ouimet bridge (1.25km long) over the Rivières des Milles-Îles linking Laval to Boisbriand will be rebuilt. The new bridge will be twice as wide, composed of two independent structures each comprising four lanes in each direction, one of which is reserved for public transport, and shoulders of three meters on each side. about 60m wide.

I stayed at the Comfort Inn in Red Deer AB in August and really got confused by the roundabouts. There were two of them that I had to go on to get to the hotel. But what really confused me were the right turn ramps! The roundabouts I've been on anywhere else were designed so you go on them and turn right off of them, not turn right and not even go on the roundabout?!?

Some have those. They are amazing.

What a joke that is, good lord just build an interchange.

There are a few of those in Ottawa

Roundabouts for people who don't like roundabouts.

I drove around this roundabout once.....The Magic Roundabout in Swindon, UK.

Bridge girders going in at the KHC work site:

I heard too. Why sheep bridge (the name) lol?

Metro-One · #**9234** Posted **Oct 22, 2021, 9:02 AM**

Hmm, I wonder why it is so expensive to build highways in BC…

There are a lot of Bighorn Sheep in the area. If you didn't get slowed down by the transport trucks in the curves, you'd have to slow down for the sheep.
