Care to start a pool on how long after the underpass overheight detectors are activated before a truck hits the underpass? Within a year?
That whole intersection of Main, Center, and Valley Drive is a disaster. It's a 4-way intersection bordering on 5-way (with the Montana Ave. truck route entering Center Ave. so close by); the intersecting streets are not aligned/perpendicular making the sightlines terrible; the underpass obscures eastbound traffic; and 3 out of 4 approaches have a stop sign but the 4th approach is free to go any direction without stopping and the signage at the other 3 stops doesn't make this clear at all. It's a wonder there aren't more accidents at this intersection.
There should be warning signs at the stop signs stating that eastbound traffic does not stop (i.e. ONCOMING TRAFFIC DOES NOT STOP, TRAFFIC FROM LEFT DOES NOT STOP, TRAFFIC FROM RIGHT DOES NOT STOP).
