There's a fair number of mostly mountainous and rural examples in southern and Sierra parts of California where you'll see freeway entrances leading to a four-lane undivided. Or the division is basically a token move; I recall there's a segment of the 118 around Rocky Peak that allows you to drive on the lefthand shoulder, left of the single-orange line (as opposed to the flush median usually painted to provide the carpool lane some distance from substantially slower general access traffic found closer to central LA) if you're a carpool during peak hours with the only thing separating you from oncoming traffic doing the same thing is a flimsy chain-link fence I wouldn't trust to stop a bicycle from crossing over. Checking street view if they finally fixed it suggests that as of June 2012 it appears to be freshly renovated to use a flush median to seperate now 24-hour carpool access and replaced the chain link with a K-rail.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
On the other hand, there is a nearly 40 mile sections of CA152 between Casa De Fruita and I-5 which at either end have miles of limited access but which I think are offically non-freeway (tagged as trunk in OSM). So it could be that the length of the limited access section is taken into consideration by CalTrans when deciding to put up a “begin freeway” sign.<br></blockquote><div><br></div><div> Well, controlled access. I consider controlled access a little higher than limited access, the difference being whether or not surface intersections and property access is banned unless otherwise unfeasible. I would consider limited access or a mix of limited and controlled access as a trunk. About the only thing I really consider a motorway would be multilane, controlled access, </div></div></div></div>
