I have a question about the speed limit on Lebanon Road. Why does it change from 45 mph (between Preston and DNT) to 40 mph (between DNT and Legacy) and 45 mph (between Legacy and 423)? I'm sure there must be a reason for the variance in speed limits. Thanks!

We conduct speed zone studies on every arterial roadway in the City at least once every three years in order to see if the posted speed limits need to be adjusted. Each roadway is broken into logical segments and studied individually. These studies will sometimes result in different speeds on different segments of the same roadway if those semgents have different characteristics.

In the case of Lebanon Road, these results are indicative of the combination of hills and curves on Lebanon between DNT and Legacy which naturally slow traffic down compared to the other segments.
