East and west-bound 435 traffic will come towards Quivira Road, which just under the bridge in the median an O.P. officer will wait. Depending on the time of day they will park using the shadow of the bridge, running Lidar.
Sometimes they will use additional units at the on ramps to catch drivers who have been clocked by the officer under the bridge, sometimes they will run radar from the on ramps individually.
Enforcement has been sporadic but usually increases at the end of the month. Enforcement has increased due to construction at the 435/69 alternate interchange east of the bridge.
