Highways with big changes at state lines

[jmacswimmer]

The only time I've driven on the East Coast is when I rented a car (actually a SmartCar Car2Go) and drove from Washington DC to Harpers Ferry.  I drove on divided highways and interstates most of the way until I did nearly the final stretch on US 340 from Maryland to Virginia.  Then it went from a divided highway to a narrow bridge with trucks coming at me.  The bridge is so narrow that the Appalachian Trail Conservancy recommended hikers not use it when the usual bridge across the Potomac River was destroyed in a derailment.  There does seem to be some walking space between the Jersey barrier and the bridge rails.  https://goo.gl/maps/PpZ1g8HiHs5fSUVB9

Speaking of MD/VA Potomac crossings...US 15 is another one.  On the MD side it is almost super-2 with full shoulders & limited intersections (and evidence of ROW existing for future widening near US 340).  Then after crossing the Point of Rocks Bridge into VA, you're immediately greeted by a sharp curve signed for 20 mph, followed by a shoulder-less country road with constant driveways & intersections on the way to Leesburg.

There is surprisingly little traffic on US 95 north of I-40 until NV 163. 

You must have far better luck than I do with that part of US 95. It seems to have become at least a minor-moderate trucking corridor, actually continuing all the way down US 95 through Needles to I-10 at Blythe, and/or CA 62. The trucks have to slow for the lumpy and curvy terrain, while hotshots in their cars and pickups try to do 70-80mph around them ... and sometimes pay dearly.

I don't think I've ever left that part of US 95 not feeling stressed out and grumpy.

I've found I-40 to I-10 to be far worse than I-40 than NV 163 on US 95.  The dips, shit line of sight and 65 MPH speed limit on US 95 between I-40 and CA 62 can get pretty wild.  That segment also gets a bunch of Laughlin gambling traffic.  Usually I tried to avoid the area via Amboy Road when I was making my work commutes between Laughlin/Bullhead and Palm Springs.

In terms of pavement condition, the portion of US-219 south of I-86 in New York State is a washboard compared to the road immediately over the state line in Pennsylvania.

You'll be glad to know this is finally being addressed with a pair of resurfacing projects.
