From Western PA, we normally take the turnpike, 70,81,66,17,95,295 and either 64 or 460. My question is, if we would attempt 495 around 8:30 a.m. and then choose Route 1 instead of 95, how's the drive and what type of road/highway 2 lane or 4 lane?
I would strongly advise against using that route (Beltway-495 to Route 1 to Fredericksburg).
If you have an E-ZPass and don't mind high tolls, you can get down 495 to Springfield and 95 quickly using the express lanes. If you continue to head east on the Beltway to Route 1 (Richmond Highway) you'll hit local traffic. You might get lucky, or you might not.
Richmond Highway is local traffic, and has many, many lights. Not something you'd want to try weekday or weekend mornings.
Again if you don't mind high tolls, you could take 95 South express lanes at Springfield. Tolls vary by traffic on the non-tolled lanes, so if those are congested, tolls on the express lanes will be very high. There are various points at which you could jump off 95 to Route 1, but Route 1 would be agony all the way to Fredericksburg. Despite being 4 lanes with a turn lane, Route 1 is really a local road and a shopping district.
When the express lanes end at Garrisonville, you're back into regular 95 traffic.
Fredericksburg itself is much better on 95 than it used to be. Local traffic for Route 17 and Route 3 has been split off into their own lanes, and that helps a lot, though there may be some slowdown where that starts.
Once you're past Fredericksburg, Route 1 is mostly rural 4 lane. Not as fast as 95, but a decent second choice before Ashland, then very slow with lots of lights. If you have to go through Ashland, stay on Route 1 which goes into 295 just west of where 95 enters.
I would not attempt to do what you want to do on a Friday or a weekend. If it makes you feel any better, the Christmas season can be even worse.
The only time you want to try this is hitting 95 south after 8:00 PM, or not returning on 95 north in Northern Virginia until 9:00-10:00 PM. I don't end know the 17 route at all, but if you know it, I'd stick with it.
