Zimmerman Trail is now open.  Let the debate begin.  I've heard from some people that they can't understand why there would be a roundabout on a highway.  I've heard other people complain that in fact, they didn't widen the road at all.  The complaint is that they just made more room for a bike path.  I'm not complaining at all.  I actually have less traffic on my road because it is open.  Better traffic flow means less congestion and more options.
