Washington Post: Virginia explores extending the 495 Express Lanes to the American Legion Bridge

Quote
A plan to expand the 495 Express Lanes to the American Legion Bridge will add three miles to Virginia’s system of high-occupancy toll lanes — and provide a critical link to the region’s growing toll network.

Quote
The proposed highway widening would complete the last leg of a tolling system on Northern Virginia’s portion of the Capital Beltway and connect to Maryland’s proposed toll lanes for its side of the Beltway, Interstate 270 and the Baltimore-Washington Parkway.

Quote
“Now with Maryland talking about [toll lanes on] their side of the river and doing something in that stretch, there is more incentive for us to move forward with this project,” said Susan Shaw, director of Megaprojects for the Virginia Department of Transportation.

If the cited plan in the article is to add 2 HOT lanes each way between VA-267 and the river, then they can finalize the rest of the upgrade plan to the VA-267/I-495 interchange. 

There are two left exit ramps from I-495 that need to be upgraded to right hand exits, and there are 6 mainline bridges of I-495 over VA-267 and ramps that are the original 1964/1977 bridges and they need to be replaced.

Is the work you mention ("the rest of the upgrade plan") part of a formal design or something you are proposing?   Was it considered in the original contract?

I was speaking generally, as I don't know what the official plan was, just noting that the interchange was only partly upgraded, the 2 HOT lanes were added each way thru the interchange area and then end a mile north of there; it seems apparent that it was unknown at the time whether the future HOT lanes extension would be one lane each way or two lanes each way; something that would depend on Maryland's future plans.  So it seemed like a full interchange upgrade with total rebuild like what happened at I-66 and I-95/I-395 would await the future HOT lanes extension project.

If the I-495/VA-267 interchange does in fact receive a full interchange upgrade, it will be very interesting to see what designs both VDOT and the potential private partner come up with.
Speaking of rebuilds, the VA-193 and the GW Parkway overpasses will likely have to get rebuilt as well. While GW Parkway interchange should probably stay relatively the same, I think upgrading the VA-193 interchange to either a DDI or SPUI could be extremely beneficial.
