PennDOT District 11 is announcing lighted chevron installation work is underway in various locations in Allegheny County.
Crews from the Power Contracting Company will replace the existing chevron signs with new lighted chevron signs, requiring shoulder restrictions in the following locations daily from 9 a.m. to 3 p.m. through Sunday, April 25:
- I-79 in each direction between the Route 51/Coraopolis/McKeesport (Exit 64) and Route 60/Crafton/Moon Run interchanges (Exit 60) in Robinson and Kennedy townships;
- Route 28 in each direction between the Tarentum/New Kensington (Exit 14) and Natrona Heights interchanges (Exit 15) in Harrison and Fawn townships and Tarentum Borough.
Additionally, starting Monday, April 5 single-lane and shoulder restrictions will occur on the ramps from the Veterans Bridge to northbound Route 28 and from southbound Route 28 to the Veterans Bridge weekdays from 9 a.m. to 3 p.m. through Monday, May 31. The Route 28 lanes beneath these ramps will undergo single-lane restrictions as needed to allow overhead work to occur.
Lighted chevrons are a Sequential Dynamic Lighting Curve Warning System utilizing LED or electric powered signs and wireless controllers with ultra-low power radar. The system flashes a series of chevron-shaped signs to warn and guide drivers through the upcoming sharp curve. These locations were selected to combat the amount of run-off-the-road crashes in the area.
