PHOENIX — The Arizona Department of Transportation is using portable message signs to help drivers avoid delays approaching a work zone on Interstate 17 south of downtown Phoenix.
The signs display travel times for the I-17, which is narrowed because of bridge construction at Central Avenue, and a detour on Interstate 10 between the stack interchange and the split near Phoenix Sky Harbor Airport.
The system uses traffic data to calculate estimated travel times to certain locations, similar to the permanent message boards along Valley freeways.
ADOT said the signs have been helping drivers save five minutes during commutes through the zone when they take the I-10 detour route.
Signs are located along westbound I-10 approaching the I-17 split near the airport as well as along southbound I-17 and eastbound I-10 in areas approaching the stack interchange.
Construction on the $13.5 million bridge project at Central Avenue started in May and is scheduled to be completed in fall 2021.
