A little insignificant concrete block building in Butler County once played a part in keeping our nations roads safe before the interstates where built.

Thousands of people have driven past the small insignificant block building on the side of US-422  which runs thru  Butler County Pa. near Moraine State Park  and the only thing that might attract your attention is the old vintage blue Embarc Phone Booth that sits by it but if you look a little more you will see remnants of a red and green traffic light on an old wooden telephone pole
while the site is obsolete and no longer used today at one point it played a significant role in protecting the motoring public from overweight and dangerous trucks in 40's to 60's  when US- 422 was one of the major routes for Tractor Trailer drivers heading east for New Jersey and the Eastern Seaboard before interstates I-79 and I -80 where completed  and this is when US-422 was mostly just a 2 lane road with dangerous curves and steep hills before it was widened to 4 lanes and straightened in many areas. .

If you where a truck driver and running overweight  or with out proper plates and tags or otherwise afoul of the law this little weigh station could get you shut down and facing significant fines and confiscation of your rig till the situation was corrected.
and more than a few trucks coming out of Ohio back in the day where stopped for violations .
Which is why the station was placed there because of the rolling hills once you got over towards Kittaning. Which has seen several horrifying accidents of runaway trucks on the steep hill leading out of town towards Indiana county
