Project Located at Bellevue/West View On-ramp to Southbound Parkway North

PennDOT District 11, in cooperation with the Federal Highway Administration (FHWA), is announcing the Work Zone Ramp Signal Project on I-279 (Parkway North) in Ross Township, Allegheny County will begin Monday, May 14 weather permitting.

The temporary ramp signal project is located on the southbound I-279 on-ramp from Union Avenue at the Bellevue/West View (Exit 7) interchange.  Equipment has been installed and is currently collecting data.

Beginning at 6 a.m. on Monday, the ramp signal equipment will be activated.  For the first two weeks, the system will operate during fixed times, weekdays from 6 a.m. to 9 a.m. and from 4 p.m. to 7 p.m.  The system may be operational during other heavy traffic periods such as sporting or special events.  After two weeks, the system will switch to traffic responsive mode and activate during heavy volume periods. The equipment will be removed once the pilot program ends in early September.

The ramp signal will manage the rate at which vehicles enter the highway.  On the ramp to southbound I-279, motorists will see the following:

  • Signs with flashing yellow lights indicating that ramp signals are in effect.
  • Signage, including “Stop here on Red” and “One Vehicle Per Green”.
  • The ramp signal at approximately mid-point of the ramp.  The ramp signal only has a red and green signal.

Only one vehicle at a time is permitted to proceed through the green signal. Motorists must stop when the signal is red.  Motorists must obey the ramp signal as they would any other traffic signal.  Drivers will merge onto southbound I-279 as they normally would once they receive the green light.

If the ramp becomes congested, the signal will operate at a faster rate to relieve the queue. The system will not be active during off-peak travel times.

FHWA selected the Pittsburgh region for this pilot project to gather data that will help engineers better manage traffic in construction zones.  The purpose of the pilot program is to improve traffic flow and reduce congestion while making the work zone safer for all motorists.

The pilot program is part of the $87.94 million I-279 Parkway North Improvement Project includes concrete patching and overlay, preservation of 30 bridges and 49 overhead sign structures, repairs to 29 walls, ramp repairs, lighting improvements, HOV lane operation systems upgrades, sign upgrades, guide rail and drainage improvements, and an anti-icing system installation on bridges at the McKnight Road interchange.

Please use caution while driving through the area.  Work zone safety is everyone’s responsibility.
