Fully Signalized Intersection - $400-$435k per intersection 2. Installation of underground equipment for future signalized intersection at Croell Ave = $80-$100k Council was split as to whether to fully signalize Croell Ave now or wait until future traffic growth warrants signalization. It was brought up that the left turn movement onto EB US 6 would still be present with a non-signalized option at Croell Ave and US 6 and whether public feedback would continue to be received on the safety of this intersection without signalization. There was also discussion from council as to whether an enhanced pedestrian crossing should be implemented at Stephens St in the form of a High-Intensity Activated Crosswalk system (HAWK Signal).
