Yes, I forgot about this blog page until I got an email notification of your post, Dom.
Beyond the mention in my previous post of a bumpy patch on Treat, it's worth noting that Third Street between Tucson and Campbell was something I characterized then as "mildly annoying." After attempting to use that stretch of road over the past year to regularly commute by bike, I'd like to revise my rating to "a complete pain in the posterior," both figuratively and realistically.
The series of deep cracks in the road surface there occurs every 30 feet or so and run full street width. Unlike potholes, you can't maneuver around them. The cracks are of the exact dimension that you can almost feel your rims bottoming out against the road surface. Riding over these deep cracks day after day has proven so annoying - and I don't want to subject my rims and tires to that abuse - that I no longer use that portion of Third Street . . . preferring, instead, any adjacent side street. Heck, even the unpaved alleys in the Sam Hughes neighborhood heading towards campus are smoother than that bumpy stretch of Third!
And . . . even through Treat Avenue is a designated an "official" bike route, crossing at the large east/west bound thoroughfares (not just Speedway) is always a dicey proposition. Much like bus routes in Tucson, all the emphasis on bike travel seems to be expended towards enhancing the east/west corridors. So, it's not surprising that the various large street crossings on Treat are largely ignored. But it really is curious to witness Third Street near the east U of A entrance being allowed to deteriorate into such a washboard-like bumpy mess (and all the more surprising when you consider the high residential property values in that neck of the woods.)
