A big roadgeeking milestone will happen this year: Interstate 95, and the original layout of the interstate highway system, will become complete.
I-95 has been discontinuous between Pennsylvania and New Jersey since the system began. It’s New Jersey’s fault (video). But now we’re near the final stage of an interchange between I-95 and I-276 on the Pennsylvania side that will enable a continuous flow of I-95 from the Pennsylvania Turnpike across the Delaware River to the New Jersey Turnpike. The completion date is a vague “August” on websites.
The Atlantic covered this in a good story in January. Conversion of the northernmost part of I-95 in Pennsylvania to I-295 happened in March with old/new exit numbering.
