Just for Show Changing Lanes

[John Holland]

The "Road Zipper" on the Golden Gate Bridge doing the morning lane adjustments (reverting from the morning rush to the normal lane assignments).

Nice clean shot, but I'm confused about what it does.

 

[John Holland]

Rob, it moves the gray blocks the width of one lane. The bridge has three lanes of traffic in each direction and the gray blocks are in the middle of the bridge separating the two directions of traffic. In the morning, the machine moves the gray blocks over one lane - thereby increasing the number of lanes on one side of the road (in the morning more lanes for the city inbound traffic).

The image below shows the "normal" traffic with three lanes in each direction

Well, you learn something every day. Thanks for that, John.

 

[Rense Haveman]

Great shot of a .... apparatus.... I love the colours especially.

 

[John Allen]

Like Rob said, learn something new every day. And like Rense said, I love the colours.

 

[Ivar Dahl-Larsen]

Well that concludes it all then. Great work John H.

 

[Brian Moore]

Cool shot, John. Actually both shots are very cool.

 

[Julian de'Courcy]

Amazing John and very informative. My first idea , it was a bullet like train running on a magnetic track which took foot passengers across. I understand the Ripper part now which is very apt.

 

[Keith Hollister]

Cool shot and even cooler machine. I had no idea there was an automated "jersey wall" installer.

What a fascinating machine. And wonderful colours.
