^ You continuously seem to believe that the -majority- of traffic congestion is caused by thru traffic, and that a bypass would eliminate the need for more lanes, whether be HO/T or GP, on I-95 and I-495, whether it be the proposed lanes, the needed ones VDOT refuses to study, or the ones already built, and that congestion would be significantly less.
You’re completely missing the fact that the -vast majority- of traffic is either local, or long-distance traffic originating in Northern Virginia / Southern Maryland coming in from I-95 from the south and north, I-270, I-66, the BW Pkwy, and other routes that lead in/out, and that an outer bypass wouldn’t divert much traffic, I’d estimate 20,000 - 30,000 AADT at most taken off the I-495 system, and that’s minuscule compared to the amount of traffic either side of the beltway has.
The completed & proposed improvements with the addition of HO/T lanes on the beltway, the need for more GP lanes and thru lanes south of I-495 would still be needed regardless of this bypass existing or not.
I agree, a bypass is needed for thru traffic. But a bypass would not eliminate the need for a megafreeway on I-95 from Fredericksburg northward, and beltway HO/T lanes. The traffic counts are well over 200,000 in the Northern Virginia area, and over 130,000 north of Fredericksburg and would remain such with or without a bypass.
