Two-way stroads almost always have cross-sections of four or more lanes.  Speed limits are usually 35-50, but in reality most will drive about 10-mph faster, restrained mainly by fear of getting a ticket.  Yet despite fast cruise speeds, average "A to B" speeds are far less due to complex 4-phase traffic signals and general congestion exacerbated by those signals.  

The “Complete Street” and "Livable Street" movements aim to tame Stroads, but when an arterial serves 25,000 to 70,000 vehicles per day, most traffic engineers are leery of "traffic calming" proposals that might reduce A to B speeds even more than signals and congestion already do.  There are a few livability-minded engineers who are willing to champion traffic calming on high-volume arterials, but they are stuck in a conundrum... How do you actually do it? 

With such volumes, it seems there is no choice but to have at least 2-lanes each direction, along with center median lanes and double-left lanes at key intersections.  That is a LOT of hardscape, and a lot of dangerous conflicts with pedestrians and other vehicles.  It's a greased and squealing pig, with planners and engineers trying to find ways to calm the pig long enough to apply lipstick, hoping the result will attract mixed-use development.  "Good luck with that!"
