Since there will likely be a long string of posts on construction zones done wrong, I want to point out that they can be done right. This is one from yesterday. Though the crosswalk closure here was less than one day, it was signed properly, and the detour was very short, about 30 feet west to the next crosswalk.
Parkway trail flood signing
Part two of posts on the parkway trail; Parkway trail low points.
When the parkway trail has been flooded this year, all the way back into December but increasingly this spring, Sacramento Regional Parks has closed various segments, and even the entire parkway at times. This is understandable. The trail is, after all, in a riparian area, and what defines riparian areas is an abundance of water.
Regional Parks has posted some information about the trail on their website, particularly as more and more of the trail has been closed, and is up-to-date with a complete closure now. In December and early January the website information was frequently out-of-date. Their Twitter account has had somewhat better information about the parkway, but it focuses mostly on motor vehicle access and not on trail access and usability.
Parts of the trail are quite usable right now, but rather than addressing those parts, all of the trail is closed.
