Bollards that extend during a crosswalk's signalled duration?

Not sure if I've seen this implement anywhere else in the world, but it would work. Would be expensive as hell and create constant traffic during construction. Also no more right on reds

> expensive as hell

That's understatement. You'd need electronic and/or hydraulic infrastructure at every intersection. It would have to be powerful enough to raise and lower quickly and durable enough to operate thousands of times a day. Then you need the ongoing expense of continued maintenance or they end up like Metro's escalators.

cheaper to just build a bridge or tunnel across every intersection at that point lol

Can only imagine the maintenance issues with them not properly retracting

Sky bridges like Minneapolis seems like a better solution

Pedestrian bridges are car infrastructure not pedestrian infrastructure.

So... Nobody can turn on a green light and we'd need to have all right and left turns on green arrows? I hope you realize this makes no sense

Ok I'm a big advocate for safe streets but retractable bollards is bordering on the insane.
