New exit numbers for a new Interstate The entire route's milemarkers would be renumbered starting at the Eisenhower Interchange (I-83), and the exits would be given the according numbers. Oddly enough, (and strictly by coincidence) the Swatara interchange, which was Exit 1 for about 30 years, became Exit 2 under the mileage-based interchange numbering but would return to Exit 1 with the I-383 exit numbering. I-383 exits
Signing for I-383 All of the standalone route markers and guide signs would obviously be modified with I-383 shields in place of I-283 and PA 283 shields. I-383 should have two control cities: Harrisburg and Lancaster. I'm sure PennDOT is tempted to use Salunga or Rheems as well; they'll just have to control themselves.
A few more thoughts I-383 goes right into PennDOT's "Fixing Things That Should Have Been Done Correctly the First Time" file. I have never heard anyone offer a decent explanation to justify the layout of the current 283/283 interchange. The fact that the facility was constucted in the late '60s makes the matter more puzzling; by then, the Department of Highways (the forerunner of PennDOT) had adopted more modern attitudes toward highway construction. Then again, the dreadful Eisenhower Interchange was conceived around the same time, so maybe the 283/283 interchange was "par for the course." In Spring 2005, the PTC began construction on a new Susquehanna River bridge and the Harrisburg East Interchange—the interchange that connects with I-283—will be reconstructed as part of the project. The project will probably last until 2008, and hopefully the approaches to 283 will be a little longer after the renovation. Since the Pennsylvania Turnpike Commission is doing work on "their side,"maybe it will be motivation enough for PennDOT to work on the 283 side.
