There are "Detour" signs, famously, on the SR-56 Bike Path and 
irritatingly on Telegraph Canyon Road and (I think) Otay Lakes Road in 
Chula Vista. The one on Otay Lakes eastbound is especially irriating 
because the "Detour" is uphill, but as you go past that detour point you 
see no construction or other reason to make a detour on a bike. At 
least, that was the situation a couple of months back.

Under what conditions are juristictions or engineers allowed the 
judegement to post "No Trucks over 2 Tons?" I thought (but have no CVC 
or case law citation) such judgements (where allowed under CVC 21, our 
favorite "mo local homegrown surprise bike restrictions" law) were based 
on the impaasability of such vehicles or the potential harm they'd cause 
  other road users, or the threat to the road they'd pose (for example, 
the no petroleum tanker rule on the Coronado Bridge). If you've got a 
road so bad it's impassble to bicycles, or one so pedestrian-covered 
you're banning bikes becuase of the harm they could cause other road 
users, then why would you allow CARS, TRUCKS or MOTORCYCLES? It's sort 
of like banning wheelchairs so you don't have to put handholds in the 
bathroom stalls.
