I don't see the point of having HOT lanes on belt routes such as I-485 and I-540.
I-495 isn’t a belt route? I-64 in Hampton Roads isn’t a belt route? Moot point.
No edge cities to speak of on I-485 and I-540.
Tysons Corner is Fairfax County's central business district and a regional commercial center, and is the 12th largest CBD in the nation based on square feet of office space.
The I-495 HOT lane system connects the pre-existing managed lane systems on I-95, I-395, I-66 and VA-267, and traffic studies showed that there would be high demand in a HOT-3 system.
VA I-495 is a heavily used local commuter route in its own right with cities like Vienna, Falls Church, Fairfax and Alexandria.
The HOT lanes on I-64 connect major centers as well, such as Navy Base Norfolk and Virginia Beach, and the pre-existing managed lane systems on I-564 and I-264.
The HRBT takes on more of the role of a radial route and a cross-harbor freeway, than that of a belt route.
