Mountain View, CA considers converting section of Castro Street into pedestrian plaza (War on Cars Watch)

But unlike cities where pedestrian-friendly streets are often part of revitalization projects, Mountain View’s proposal may be more out of necessity.

With the electrification of Caltrain, cars won’t be allowed to cross Castro Street. Traffic has to be rerouted — either by building an overpass or an underpass, which could cost upwards of $100 million dollars, a less expensive option is the pedestrian plaza.

Many business owners also like the idea of a pedestrian plaza, but are concerned about the impact rerouting traffic may have on foot traffic.
