US Highway 60 – James River Fwy near Republic Road
I’ve seen Springfield officers set up several times on the James River Freeway, in particular on weekday afternoons. Usually they park in the median under the Republic Road overpass east of Kansas, right up next to the bridge pillar. On a sunny day, it’s very hard to see them lurking in the shadows down there.
From there they’ll watch westbound traffic on the freeway, and since it’s a clear line of sight for quite a ways they have plenty of time to lock the radar gun on you as you approach. It seems like anything less than 10 over the limit is safe, but beyond that you’re on your own.
