New traffic patterns set for I-83 at York split

Construction crews plan to set overhead sign trusses over Interstate 83 and shift traffic at the Route 581 interchange in Lemoyne next week.

The sign trusses will be set during the overnight hours of Tuesday, May 20 if weather permits, according to a PennDOT news release.

Drivers may encounter 15-minute traffic stoppages on I-83 northbound and southbound while the structures are put in place.

The following night, northbound I-83 will be restricted to a single lane and traffic will be shifted to the newly widened portion of I-83 North.

The new ramp from I-83 North to Lowther Street in Lemoyne at Exit 41-B will be opened to traffic and the existing ramp will be closed.

PennDOT spokesman Mike Crochunis said drivers headed from I-83 northbound to Lowther Street should be aware that the new exit is before the Route 581 East merge, and is approximately one-quarter mile before the old ramp.

Also, Route 581 eastbound traffic to Lowther Street will no longer be allowed to use the existing Exit 41-B from I-83 North once the existing ramp is closed.

Eastbound Route 581 traffic to Lowther Street will be required to use Exit 6-B to I-83 South then take the existing Exit 41-B to Lowther Street.

More changes are planned overnight Thursday, when I-83 South will be restricted to a single lane and traffic will be shifted to the area currently carrying the temporary northbound I-83 lanes.

With the new traffic pattern, southbound drivers will no longer have access to Lowther Street at Exit 41-B, but will have to exit at Exit 42 for Lemoyne and use Lowther Street to access the Highland Park area.

Exit 42 is approximately one mile before the existing Exit 41-B.

The following week, during the overnight hours of Tuesday, May 27, drivers on Route 581 should expect 15-minute traffic stoppages eastbound and westbound as overhead sign trusses are set in place.

Overnight Wednesday, May 28, crews will move the concrete barriers 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 be required 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.

The existing stop sign at the bottom of the Route 581 East ramp to I-83 South will be replaced with a yield sign.

In advance of the traffic changes, PennDOT has developed several short videos depicting the existing ramp movements that will be eliminated and the upcoming traffic changes. These videos are available at

The web page also describes several more ramp configurations and traffic movements that will be made in the coming months.

The work is part of a $22.1 million project to will make improvements to the I-83/Route 581 interchange and adjacent ramps.

The project is scheduled for completion in the summer of 2015.
