The Pennsylvania Turnpike Commission has started to remove the red, yellow and green traffic lights used as feedback signals.
The signals are used to provide feedback to E-ZPass drivers indicating their transponders were properly read. The signals, however, are now prohibited for such use by federal guidelines, according to the commission.
Commission COO Craig Shuey said signal light technology currently in use is outdated and cumbersome. The turnpike is incorporating new federal signage standards as it updates toll equipment to modern hardware.
Work began with the Harrisburg West Interchange, and the commission said customers may temporarily see the decommissioned lights wrapped in yellow plastic at certain Harrisburg-area interchanges, and at E-ZPass Only interchanges north and east of Philadelphia.
The signals will go away at several interchanges each month until the upgrade is completed by the end of the year.
