During my warm-up and cool-down walks, I stopped to check on the progress of the extension of the Parkway path. They apparently have dug the path up to 9400 South, and they have put down gravel and sand on the path. When I finished my run and was walking to cool down, I saw a large roller compacting the road base.
The first part of the extension looks nice. There are Russian Olive trees on both sides of the path, which should give shade in the early morning and late evening. The river is just a few yards from the path, which means that there will probably be ducks on the path begging for food.
