Those signs were a topic at this past Tuesday's BAC downtown subcommittee meeting. Apparently the city put out a dozen and half of them were gone overnight. The theory is people think the graphic is funny and take the signs. These were actually unbolted from the supports which took some time to accomplish. The issue of signage in the construction zone has been ongoing. Jesse Gutierrez the project manager for the city of Tucson has used vandalism as the explanation for why the signage has been so haphazard and ineffective. Perhaps but the vandalism isn't really the majority of the problem. If you are constructing a lowered speed zone it seems pretty basic to bag or block the regular speed limit signs. They managed to do this on Grant Rd approaching Oracle. In general the traffic control measures have been ineffective and poorly implemented. Euclid is a living hell to try and traverse because the automobile speeds haven't been controlled. It seems pretty clear the the resources devoted to maintaining safe and adequate bicycle pedestrian access throughout the modern st car construction zone have been inadequate. You wouldn't paint the interior of a house without using drop cloths, why would you build a street car line and neglect controlling traffic and providing for bicycle pedestrian access? This should have been a larger line item in their now 192 million dollar budget. Currently the mantra of the project team seems to be it's stopped raining and this will all be over soon. The reality is it won't be over any time soon the problem is just going to move east and west towards the terminuses.
