History
Construction began on I-283 in 1968.
Previously, the Harrisburg East interchange of the Pennsylvania Turnpike connected directly to Eisenhower Boulevard. The section from the turnpike to PA 441 opened in 1970 and included a short portion of what is now PA 283, connecting Eisenhower Boulevard to the exit 1 cloverleaf. The next year, the Eisenhower Interchange opened to traffic along with the remaining section of Interstate.
As part of a project to reconstruct of PA 283, the interchange between I-283 and PA 283 is being improved.
The ramp from westbound PA 283 and northbound I-283 is being widened to two lanes, and the loop ramp from westbound PA 283 to southbound I-283 toward the Pennsylvania Turnpike toll plaza will be removed and replaced with a left turn and a traffic signal. This will eliminate the problem of
traffic weaving
In civil engineering (more specifically highway engineering), grade separation is a method of aligning a junction of two or more surface transport axes at different heights (grades) so that they will not disrupt the traffic flow on other tra ...
between the aforementioned loop ramp and the heavily-traveled loop ramp from southbound I-283 to eastbound PA 283. The project is projected to be completed in late 2020.
