Since I would hope they are of standard size you might think a few covers on the shelf would be appropriate. There is one on Ocana at Constitution with a large steel plate, been there for over a year.
In my humble opinion the roads dept is doing a real crappy job pretty much all the way around at least for the local streets. Contractors on some of the big jobs seem to do whatever without regard for the public. Drive out Ocana today. Boths sides ripped up with cross trenches for sewer, I guess, resulting in craters to negotiate. Traffic going both ways on both sides, no signs no plan to manage traffic. Huge piles of earth randomly on both lanes of traffic. Some sideroads closed off some open.
Avoid Ocana at all costs right now 3/3/2114 !!
