The Oklahoma Department of Transportation (ODOT) will do its final round of testing 21 electronic signs in Oklahoma City, on Wednesday.
The electronic signs were installed over the course of the past few years, and the agency plans to set up more near the borders of Texas, Arkansas and Kansas.
Special sensors measure speed of the cars passing through and send the data to a computer system which posts the information to the signs. Along with real-time travel information, Amber Alerts, Silver Alerts and weather-related road closures will be posted as well.
So far signs are on I-35, I-40, I-44 and on Broadway Extension.
ODOT plans to display this information every weekday from 6 a.m. to 9 a.m. and 3 p.m. to 6 p.m. The agency says the boards will be in full use beginning Monday, November 10.
