New AAPS Installation in Downtown Boise at Ada County Courthouse

Campbell Company’s Advanced Accessible Pedestrian System (AAPS) is part of a new traffic signal and crosswalk installation at a busy street crossing at the Ada County Courthouse in Boise, Idaho.

The crosswalk was installed directly in front of the Ada County Courthouse where officials estimated that 80 people per hour were illegally crossing Front Street, a major 5-lane traffic corridor in the downtown area.

This is the forth AAPS installation Campbell Company has completed for the Ada County Highway District since last September in downtown Boise.
