Lone Tree Blvd is the Hwy 4 bypass that goes thru Antioch, CA. and Brentwood. The last few blocks of Lone Tree near Sutter Hospital (Antioch) have varying speed limits that are used to catch you speeding. The consistent speed limit is listed at 45mph for 95% of this street, toward the end you have 6 blocks listed at 35mph and the last 4 at 30mph.

They caught me and I had not realized what had happened as I was going with the flow of traffic. I have paid attention to this and have realized that they are more active in the morning and towards the end of the month.
