Traffic restrictions scheduled at I-17 and Indian School Road this weekend as project to install wrong-way vehicle detection system kicks off

The first traffic restrictions required for the installation of a first-in-the nation pilot wrong-way vehicle detection and warning system are scheduled this weekend at the Interstate 17 interchange at Indian School Road in Phoenix.

The Arizona Department of Transportation’s $3.7 million thermal-camera based project is designed to immediately alert ADOT and the Department of Public Safety if a wrong-way vehicle is detected along a 15-mile stretch of I-17.

Indian School Road will be closed in both directions at I-17 from 9 p.m. Friday until noon Saturday (Aug. 19) for the mounting of thermal cameras, installation of fiber-optic cable and rewiring of control cabinets in the area. Both I-17 off-ramps at Indian School Road will be closed. Drivers should plan for delays and consider alternate routes, including Camelback or Thomas roads. Indian School Road traffic approaching I-17 will be required to make right turns onto the freeway’s frontage road or on-ramps.

Future restrictions will be scheduled at other I-17 interchanges between I-10 northwest of downtown and Loop 101 in north Phoenix as the project advances this fall. No restrictions will be scheduled over the Labor Day holiday weekend. Following installation and testing, the system will be fully operational by early next year.
