Tall and Strange Bus Stops Erected at Roosevelt El Stop?

The Roosevelt Road streetscape improvement work is still in full swing.  We're excited to see what the finished product will look like, but until then it hasn't been super smooth.  Yesterday we posted about some spelling issues with some of the pavers and benches.

Today a reader sends us a photo of some massive structures that have been installed on the south and north sides of the Roosevelt CTA stop:

While we're not 100% sure what these are, our guess is that these structures are two fold:

1. It looks like it's forming a shelter, so we think it might be a bus shelter of some variety.
2. We also are pretty sure these will be "neighborhood signage" which is something we read about during this project.  As you can see in the rendering below, there are some huge yellow structure that resemble what is currently being built:

Can anyone confirm what these are?  Or have seen renderings of what the finished product will look like?
