Rapid City, South Dakota Speed Traps
St. Joseph Street near School of Mines and Technology
Frequently there is a radar set up in the parking lot of O’Harra Stadium on St. Joseph Street, and the police cars are not detectable because the Mineral Industries building blocks the view of the parking lot due to a curved road. The speed limit is 35, and as soon as anyone speeds past the building, they are open to police radar.
Sturgis Road near Hidden Valley Road
Beware of South Dakota Highway Patrol and Pennington County Sheriff’s Dept. speedtraps on the stretch of Highway 79 North (better known as Sturgis Rd. or Black Hawk Rd.) between Rapid City and Black Hawk. Usually they work this area heavily on Friday & Saturday nights. Most often they set up near the Hidden Valley Rd. intersection, but they often turn up anywhere between the bowling ally and Black Hawk. The speed limits on this road are ridiculously slow.
State Highway 44 near Twilight Street
There is an unused (new) bridge going over hwy 44 east of Rapid City. There is one patrol car on this unused bridge taking speed measurements. Approximately .25 mile east from that, there are 3 to 4 patrol cars pulling over people that the patrol on the unused bridge measure as speeding over the posted limit.
The posted speed limit is 45 mph at that point, which is not an unrealistic limit due to merging roads (traffic) in the area. I don’t know if this qualifies in your definition of a "speed trap" and i did not get a ticket (as I rarely go over the posted limit)but, I feel as though my liberty had been stripped away.
8th Street near Main Street
On friday and saturday nights(friday night special) all the locals are out cruising 8th street. from omaha st. to the exxon station at the top of 8th(after 16 turns to 8th)the police are out in full force. locals out here like to race down the streets, so the police hide out in driveways,alleys,businesses,etc. it’s 35mph from exxon to kansas city st. then it changes to 30mph, then 25mph right before st. joseph. i’ve been pulled over when i was downshifting to the speed of 25(i was going 30). not really a trap, but close enough.
Haines Ave, across from Lowes at the closed Laundrymat.
Sits in the lot behind the building watching cars heading towards I-90. The speed limit is 40 on the 2 lane, then drops to 35 when the road goes to a 4 lane.
