These can be found on NB Championship Pkwy at US 380 in Frisco, Texas
There are two of them, and they have 25 reflectors each.
The reason for their presence, and the presence of the barricade to which they are attached, is that Championship Pkwy has to shift over before reaching US 380 in order to align with Teel Pkwy, which is still a two-lane road. It is worth noting that the street layout/ naming in this area creates a gap in Teel Pkwy.
