Ramp metering is now in use on I-465 between I-65 and I-70. It controls the frequency of vehicles entering the roadway to match traffic capacity through traffic signals at on-ramps. Ramp metering started early Tuesday, May 14, but vehicles were not pulling up far enough to activate the signal. Mobile signage has been added to help drivers know where they need to stop. Active testing will continue and crews will continue to closely monitor ramp metering locations. Drivers should continue to follow signals at each ramp.
Signals cycle between red and green to indicate to motorists when to merge. On a red light, the driver should stop at the white stop bar. When the light turns green, only one vehicle per lane should continue onto I-465. The next vehicle on the ramp should pull up to the white line and wait for the green signal to enter I-465.
When the meter is not in use, the signals will flash yellow, and merging will resume as normal. If the ramp gets full while the meter is in use, the signal will adapt to traffic conditions and increase the rate at which it allows vehicles to proceed onto I-465.
