Preliminary engineering and environmental studies were completed in 2014 on the section of I-83 between the junction with I-81 and the Union Deposit Interchange, which is just to the north of the Eisenhower Interchange. Work on the corridor has been split into two separate construction contracts. Contract 1 construction is expected to be completed by the end of 2018 or early 2019. Contract 2 will include the widening of the I-83 roadway and construction of four new mainline bridges, retaining walls, and sound barriers. Union Deposit Road will be resurfaced and new sidewalks will be installed. Contract 2 was bid on June 21, 2018 and construction was completed in 2022.
The I-83 Master Plan Study focused on transportation planning for the section of I-83 from the New Cumberland Exit to the junction of I-81, a distance of 11 miles. The study identified specific projects, such as the improvements to certain interchanges, that can be programmed and scheduled into PENNDOT’s highway planning process. The overall goal of the I-83 Master Plan is to preserve the quality of life and to promote economic viability in the Harrisburg area by providing an effective transportation plan for the I-83 corridor.
In the summer of 2015, PennDOT completed construction of the I-83 / PA 581 Interchange Bottleneck Safety Project. This early action project addressed safety and congestion issues at the I-83/PA 581 interchange, commonly known as the York Split, where I-83 northbound traffic had previously been reduced to a single lane, creating lengthy queues and delays for commuters. Project improvements included the addition of a second northbound lane through the interchange and an extension of the auxiliary lane across the John Harris Bridge to the 2nd Street interchange in Harrisburg. Other improvements modified, relocated or eliminated ramp movements within the project corridor improving traffic flow by eliminating conflicts associated with traffic weaves and extending acceleration and deceleration lengths. Since completion of the project, commute times have been drastically reduced for northbound traffic.
As part of the nationwide economic stimulus program, PennDOT has resurfaced a two-mile section of I-83 from the I-81 Interchange to the Union Deposit Interchange. The work consisted of milling and resurfacing the northbound and southbound lanes of I-83 to improve the ride quality, and reconfiguration of the southbound off ramp at the US 22 interchange.
