New tunnel under the Brisbane River - 7km (4 miles long) including approaches.
State government publicity claims 4 speed cameras in the tunnel/s.
Fact is there appears to be only 1 radar (k-band) speed camera at the end of the northbound side (2 lane tunnel).
Perhaps the other side uses different technology: point-to-point?
Radio stations have blithely repeated the 4 "camera" story.
Anyone else taken the trip with a detector?
