First Diverging Diamond Interchange in Central PA

[jpi]

Exit 4 of I-83 at PA 851 in the growing "exburb" of Shrewsbury. Could we see another central PA road meet by 2019??

Well I guess we should also keep track to see if I-83 gets widened to six lanes in York before scheduling that.     (older link)  I do not know much about Shrewsbury itself, but I have noticed that going south on I-83 services seem to be somewhat limited between there and the Baltimore suburbs.

Good point about the widening, will keep an eye on this, Shrewsbury is one of the larger boroughs in southern York County and has grown by leaps and bounds in the last 20 years so there is more services off that exit then any other exit between Leaders Heights (exit 14) and Hunt Valley (exit 20) in Maryland.

There are a fair bit of services at Exit 4 (which I've sometimes partaken in).  Some of it is that the area is just as much bedroom community to Baltimore as it is a suburb of York.  There's a bit of money in northern Baltimore County so that has also inhibited growth between the Hunt Valley area (Exit 20 in MD) and the state line.

As for this interchange becoming a DDI, color me unsurprised.  851 is pretty narrow underneath and to fix that would require a complete replacement of the I-83 overpass over 851.  And there's a lot of turning traffic at the interchange, especially to/from the west on 851 (where the vast bulk of commercialization has been).  This is PennDOT's attempt to squeeze as much capacity as they can out of the interchange without a full (and expensive) rebuild.

Which, according to the article, is being completely replaced with a wider span that can potentially accommodate 6 lanes.

Well PennDOT says it will officially be a DDI.
