Non designated truck route?

I made the delivery just fine! I called the Bellwood Police department and while the shift manager said the person available for truck routes wasn't going to be in for a while they did say that if it's a non designated truck route it means local deliveries only essentially. They couldn't confirm or deny the 65 ft restriction designated by the state of Illinois but said "it should be fine". There is a truck stop on 25th actually and the police department has a extension to request overnight parking which they said needs to be used if entering a non designated truck route, not delivering, and staying for a "period" of time. You give them your license plate of tractor and trailer.

The warehouse I went to was kind enough to give a turn by turn and confirm taking 25th st. They did say sleeper cabs come through often and they often get in "trouble" because of how tight it is to navigate and take out structures. This would imply to me that the 65 ft restriction is probably active but is rarely enforced because there is sleepers everywhere.

 

Oh yeah I have a Garmin 710 I just use Google maps for look at satellite view and street view for the getting into places so I can become familiar before I get there. All the navigation is done with my Garmin though

 

No doubt! That's why I use street view and satellite view in conjunction to my routing. I can "walk through the route" the second I get off the exit. I can see all the street signs and bridges. If I'm ever not sure I can use my Rand McNally motor carrier Atlas that lists truck routes, low clearance, and weight limits. That being said I wasn't sure of that sign I showed in the original post. The Garmin said send it but like you said you've gotta be cautious of that.

If I didn't make this post I probably would've just proceeded with caution adhering to any sign I could find. It did make me feel better that there was a truck lane sign a block up from the one in question. That being said I learned some great tips from people here like contacting local police departments. I've also learned that while the Garmin is convenient you can confirm this by looking up state specific truck maps because they're usually even more detailed.
