The ramp from U.S. 30 to southbound Intertstate 55 will be closed 9 tonight until 5 a.m. Wednesday to install detector loops in the pavement and fiber optic, according to a village of Plainfield news release.
The work is being done by the Illinois Department of Transportation and is similar to the work that was completed last week on the ramp from U.S. 30 to northbound I-55.
Detector loops are located below the pavement and can sense when a vehicle is waiting, alerting the traffic signal to change. They can also be used to monitor traffic.
