Concerned Yorkers will get a chance to voice their opinions Wednesday on proposed improvements to the Interstate 83 exit in Shrewsbury Township.

The state Department of Transportation will be holding a public meeting for people to look at the two proposed improvement options for the Exit 4 interchange between I-83 and Route 851, according to a release. The meeting will be held from 6 and 8 p.m. Wednesday at the Shrewsbury Volunteer Fire Co., 21 W. Forrest Ave.

The meeting will be an "open house" format, and anyone can come at any time during those hours. Project personnel will be there to speak to the public and answer any questions or concerns. The information regarding the options will also be on display for the public to view.

The meeting's purpose is to show two improvement options that were studied for the interchange. The first option is a tight diamond interchange, similar to its existing configuration, but with two eastbound and two westbound lanes on Route 851, with left turn lanes onto north and southbound I-83.

The second is a diverging diamond interchange, a design that would be new to the area. It would have two eastbound and two westbound lanes on Route 851, utilizing signalized ramp intersections to cross traffic over the left side of the road, with a return to the right side within the interchange limits, according to PennDOT.

Here’s a PennDOT graphic of the diverging diamond interchange (DDI) option for Interstate 83’s Exit 4 in Shrewsbury. The department describes the DDI as “unique from a standard diamond interchange in that the side road traffic (PA 851), crosses over to the left side of the road at a signalized intersection prior to the bridge. This allows direct left turns from the off-ramps to merge and allows for a direct left turn on to the on-ramp. The side road (PA 851) traffic crosses back to the right side of the road at a signal beyond the bridge.”

The improvements for the exit may begin in 2018, according to the release.
