same amount of lanes and just pushing you over or less lanes? that area is like jacksonville, its been under construction for 30 years.

there were some massive potholes in that area.
On I-81 through the Chambersburg, PA, area, the lane change is confusing to read. I can't even sum it up so I am posting the info that was in the local paper:
CHAMBERSBURG -- Motorists need to stay alert on Interstate 81 through the Chambersburg area this week as changes -- including an express lane -- begin.
According to the Pennsylvania Department of Transportation, from 3 to 6 p.m. Tuesday, traffic is to shift on Interstate 81 northbound and southbound, weather permitting.
Northbound I-81 traffic will split south of Exit 14 for Pa. 316/Wayne Avenue. The northbound right lane will shift into the passing lane and continue to use the existing northbound roadway. Exits 14, 16 and 17 will be accessible via the northbound right lane.
The northbound left lane will split south of Exit 14, cross over the median and use part of the existing southbound passing lane and the newly constructed auxiliary lane. The northbound left lane will act as an express lane, serving only through traffic and will not be able to access exits 14, 16 or 17. The left lane will cross back to the northbound roadway north of Exit 16.
A series of signs notifying motorists about the northbound I-81 express lane will start 11/2 miles before the crossover.
Southbound I-81 traffic will shift to the right, using the existing southbound shoulder, right lane and a portion of the passing lane. This pattern will start north of Exit 16 (U.S. 30/Lincoln Highway) and continue through Exit 14.
All I-81 southbound lanes will have access to exits 16 and 14. The contractor will place temporary concrete glare-screen barrier to the left of the southbound

lanes to separate southbound traffic from the northbound express lane.
Traffic is to remain in this pattern until next August.
Average daily traffic volumes on I-81 here is 45,500 to 49,700 vehicles.
The overall project should be completed by the end of May 2011.
