The drive to work and home again will look different next week for drivers who travel the Interstate 83 and Route 581 interchange in Lemoyne.
New traffic patterns and ramp configurations will be implemented as early as Thursday, May 15, according to a PennDOT news release.
During the nighttime hours Thursday, crews plan to reset the concrete barriers and shift northbound traffic to the newly widened portion of I-83 North.
Once that happens, the new ramp from I-83 North to Lowther Street at Exit 41-B will be opened to traffic, and the existing Exit 41-B ramp will be closed.
Drivers should know that the new exit is before the Route 581 East merge, and about a quarter-mile before the old ramp.
Eastbound traffic on Route 581 to Lowther Street will no longer be allowed to use the existing Exit 41-B from I-83 North once that ramp is closed, and will have to use Exit 6-B to I-83 South then take the existing Exit 41-B to Lowther Street.
More changes are planned during the nighttime hours of Friday, May 16, when crews will shift I-83 South traffic to the area currently carrying the temporary northbound I-83 lanes.
Once I-83 southbound traffic is shifted to the east, drivers will no longer have access to Lowther Street at Exit 41-B.
Southbound I-83 traffic to Lowther Street will have use Exit 42 for Lemoyne and Lowther Street to access the Highland Park area. Exit 42 is about a mile before the existing Exit 41-B.
Finally, on Saturday, May 17, crews plan to modify the traffic pattern on the ramp from Route 581 East to I-83 South and the exit to Lowther Street.
In the new traffic pattern, eastbound Route 581 traffic to Lowther Street will have to use Exit 6-C for Lemoyne. Exit 6-C will exit along with traffic to I-83 South.
The ramp will widen to two lanes shortly after the exit, with the right ramp lane exiting to Lowther Street. Southbound I-83 traffic will use the left ramp lane for Exit 6-B to merge onto I-83 South.
As part of this traffic switch, the existing stop sign at the bottom of the Route 581 East ramp to I-83 South will be replaced with a yield sign.
PennDOT has several videos depicting the new ramp movements and those that will be eliminated. The videos are available at www.i-83beltway.com/ess1/i83pa581local.html.
This work is part of the $22.1 million contract that will make several safety improvements to the I-83/Route 581 interchange and its adjacent ramps. The project is scheduled to wrap up in summer 2015.
