I-40 restricted near Topock for installation of weigh-in-motion technology

Work part of project to upgrade sensors at all I-40, I-10 ports of entry

PHOENIX – Interstate 40 will be narrowed to one lane in both directions at the Topock Port of Entry near the California state line starting Monday, Aug. 5, so crews can upgrade weigh-in-motion sensors as part of a statewide project, according to the Arizona Department of Transportation.

Drivers traveling between California and Topock can expect the restriction to be in place from 6 a.m. to 6 p.m. through Friday, Aug. 16, and should budget extra travel time.

This work is part of larger project that will replace weigh-in-motion sensors at the ports of entry along I-40 and I-10 on the eastern and western sides of the state with upgraded technology.

Weigh-in-motion technology allows officers from ADOT’s Enforcement and Compliance Division to check the weight and registration of trucks without requiring the trucks to stop. Sensors in the roadway check a truck’s weight, and cameras check identification numbers to be sure its paperwork is in compliance with state requirements.

In addition to the ports of entry, there are currently three weigh-in-motion stations elsewhere in Arizona: along I-17 near the McGuireville Rest Area, along I-10 near the Sacaton Rest Area and on I-19 near the Canoa Ranch Rest Area.
