This is a well-traveled artery connecting I-279 to McCandless and Franklin Park.
After hours in the Nations Rent (?) parking lot, there is often a Ross Twp unit lying in wait. There is also another zone I haven’t seen, possibly the Sir Pizza lot 1/8 mile down the road toward 279. They won’t tag you for going moderately above the posted limit, but they are definitely on the lookout for erratic driving, line crossing, or running the light at Rochester and Sewickley-Oakmont/Reis Run Rd.
