If the Blue Route seems packed now, just imagine what it will be like in 2040, when the region's population has grown by 600,000 people, an 11.5 percent bump.
More cars. More Shore traffic on Friday nights in summer. More logjams when the Phillies are in town.
But relief may be on the way. Regional planners are floating a plan to convert the shoulders of I-476 during rush hour, easing traffic flow during the busiest times without spending money to widen the road.
During peak hours in the morning and afternoon, vehicles would be allowed to drive on the shoulder, creating a bonus lane for the estimated 90,000 drivers that use the road each day.
