Ramp and Shoulder Work Scheduled as Preparations Begin to Rebuild Exit 4 Interchange and the I-83 Bridges over Route 851; Shoulder paving, median construction, traffic shift will precede first phase of construction

03/18/2019

Harrisburg, PA – The Pennsylvania Department of Transportation (PennDOT) today set long-term work zone signing marking the start of a project to improve and reconstruct a new interchange at Interstate 83 Exit 4 for Route 851 and Shrewsbury Borough in southern York County.

The $29,867,900 Diverging Diamond Interchange (DDI) construction contract was awarded on February 13, 2019, to Kinsley Construction, Inc. of the City of York, York County, and includes replacing the northbound and southbound bridges that carry I-83 over Route 851 with two-span structures allowing enough clearance for Route 851 to be widened to four lanes and realigned into the DDI configuration. Work under this contract will also lengthen and reconstruct the on and off ramps within the interchange, replace the culvert that carries Deer Creek beneath the interchange, and install traffic signals, drainage, sidewalks, stormwater management facilities, highway lighting, guiderail, signs, and pavement markings.

In the Spring of 2016, PennDOT selected the DDI configuration option for the new I-83 Exit 4 interchange upgrade with Route 851 following a public information meeting held March 30, 2016, at the Shrewsbury Volunteer Fire Company.

Work this spring will focus on preparations to relocate underground utilities along Route 851, construct portions of the box culvert that carries Deer Creek and reconstruct the I-83 median to prepare for future stages of construction. Two lanes of traffic will be maintained in each direction along I-83 during construction except for short-term off-peak lane closures to adjust traffic patterns.  PennDOT expects the project to be completed in the Summer of 2021.

PennDOT advises travelers that they may encounter single lane restrictions on I-83 and Route 851 in either direction during overnight hours, 9:00 PM to 6:00 AM. More than 45,500 vehicles per day travel this section of I-83. This section of Route 851, locally known as East Forrest Avenue, averages more than 10,500 vehicles traveled daily. To avoid delays, travelers should allow for additional time in their plans or seek an alternate route.

Motorists are reminded to be alert for these operations, to obey work zone signs, and to slow down when approaching and traveling through work zones, not only for their safety, but for the safety of the road crews.
