Mountain Biking

If you are crossing the Nickel (Boulevard) Bridge as a pedestrian on the sidewalk, anything other than a tip-toe is not acceptable. As I approached the bridge this past Saturday morning, the sign that greeted me state "NO JOGGING OR BIKE RIDING IN WORK AREA"...meaning the sidewalk. The actual work area is under the bridge; granted some workers have to be on the sidewalk and there is some small work equipment but that's about it. Realistically, what biker...or, especially runner/jogger, is going to stop and slowly walk that 1/2 mile distance across the Nickel Bridge? Maybe 2% of the population crossing would comply. What makes this signage even more of a problem is that it seems to empower other individuals who feel the need to try to police these rules themselves. This causes conflicts that could easily be avoided. Personally, I've had a number of situations where individuals, either in a vehicle crossing the bridge or other pedestirans either physically blocked my path or hurled orders and insults to try to get me off my bike.
The signage would be more appropriate if it read something like "PROCEED WITH CAUTION: WORK AREA AHEAD". I suspect that this probably won't happen so my advice is to all who cross the Nickel Bridge, do so with caution - both in the respect for the work area and that fact that the citizen bridge police will probably be present.
