Alpine Road never used to be a truck route. I have lived on Alpine for nearly 60 years and remember when people rode their horses from Webb Ranch to the Red Barn at Stanford. Menlo Park and Stanford negotiated to widen the intersections at Alpine and Sand Hill and after that there appeared a sign within the MP city limits by Rural Lane stating that Alpine is a Truck route. Prior to that sign, the instructions on Stanfords website for contractors told them to use Sand Hill. The "Truck Route" sign also appeared just before Stanford engaged in massive construction with double semis coming from Campus Drive West at the rate of one about every 17 seconds. It took a substantial number of constant complaints to the then president of Stanford to get this changed so that the trucks used Sand Hill during much of the construction. However, this has changed and more trucks are using Alpine. This makes no sense since the entirety of Sand Hill Road has signs forbidding large trucks.
It is extremely dangerous for trucks to be using Alpine since it is a 2 lane road with blind corners, no traffic lights, and no law enforcement. About 350 families live in Stanford Weekend Acres and are in peril from these trucks when they try to get into or out of their homes. The trucks also often veer into the bike lanes and frequently speed.
I checked Google to find out how truck routes get designated as such and found:
"Truck Route means the roads or streets in a city which have been formally designated by the city council as the roads or streets on which trucks must travel when proceeding through the city."
If this is true please refer me to the relevant City Council ruling. If it is not true what are the means to get trucks off Alpine Road?
