Ramp Meters Coming To I 476
The Pennsylvania Department of Transportation will activate ramp meters between now and late march at 14 ramps going onto Interstate 476 in Montgomery and Delaware Counties.
PennDot’s Gene Blaum says they are red and green lights that tell motorists when to stop and go, similar to regular traffic signals, but with an important difference.
“The green light is good for only one vehicle at a time to proceed onto 476. The theory is that by staggering the rate at which the vehicles coming onto the highway enter the highway, there will be larger gaps in traffic for them to enter safely, plus the main line of the highway is going to be moving at a much smoother flow, because you do not have a large crush of vehicles all trying to merge their way onto 476 at one time.”
Blaum says getting onto the highway might take a little longer, but motorists going a few miles should make it up once they are on the highway because traffic will flow better. The Montgomery County ramp meters, at Chemical Road, Germantown Pike and Ridge Pike on-ramps in Plymouth Township, should be operating by mid to late March. Initially they will be turned on only during morning and evening rush hours.
