US-13 in Maryland (between Salisbury and Pocomoke) is higher quality than US-113, IMO, given it has limited access throughout without private driveway connections, then of course the full freeway bypass around Salisbury.
The only problem that makes US-13 less viable, however, is Delaware.
US-113 in Maryland is still a high quality roadway though.
If a true freeway was ever sought after on the Eastern Shore, I’d say use a majority of Delaware’s US-113, a majority of Maryland’s US-13, then build a connector between the two north of Salisbury.
US-13 in Virginia is a joke - and they have still continued to add new signals.
13 in VA on the north side of the CBBT is absolutely miserable. One local yokel triggers the light to turn red at various signals through there. It's absurd and infuriating.
Pretty much. After slogging through 2-4 signals in a town that are definitely not timed together, the speed limit bumps up to 55 mph, you might get to cruise for a few minutes at 65-70 mph, then you hit the next town, and repeat. 60-ish miles later, you enter Maryland, get to US-113, and finally where you can set the cruise at 70 mph and go on about your day without any more interruptions, at least not nearly as frequently.
Then you hit Delaware, and it's Virginia's situation on repeat, except with significantly more traffic.
VDOT seemingly treats US-13 as a local roadway, and not as a high quality arterial highway with a goal of limiting signals through RIRO, J-Cuts, and even strategically placed interchanges at high volume intersections. A few town bypasses as well. Even without a full freeway treatment, US-13 needs some sort of upgrading in Virginia.
