General Road and Highway Discussion

Walked down Columbia St. today, starting to see some finished products.  Segregated bike lanes are visible on one side.

Here's one confusing thing, I'm guessing this is going to be a bus stop.  I have no idea why there are tactile plates between the bike lane and the bus stop.

   

Also, the segregated lane seems to end here, which is strange, it's about 100 meters back from the traffic circle, but there seems to be a barrier curb preventing cyclists from getting to the sidewalk.  I will be curious to see this in a finished form.

   

One other interesting thing I got to see, is what looks like mechanically stabilized earth (reinforced soil) being used to build up around the valley that is being levelled.  I've never seen it under construction before so that was interesting.

You can see down low one layer of the stabilizing material placed down.

   

Here is a closeup of the stabilizing material.

   

As little as I understand of the process, I believe it only needs to resist tension, not be rigid it any other direction.
