Bayou Greenways 2020 Progress

Don't get me wrong, I love Bayou Greenways and I know things take time / get delayed etc. but what is the hold up on some of these projects?

Here is the map of current projects and planned projects

I know I didn't expect all of these to be done by 2020, but it seems like they all won't be done even by like 2025.

I live in Alief and the Brays extension would be so valuable in allowing me to commute. There are no safe crossing for Beltway 8 and 59 in Southwest Houston.

I feel like we are so close as a city to making bike commuting work. But these gaps are rough. Wish it was more of a priority for city / county (I know BG2020 is a private group).
