Route 50/Loudoun County Parkway Interchange Design to Get Review

The design of the interchange planned at Route 50 and Loudoun County Parkway will undergo new analysis out of concern that previous models of the project made assumptions about the completion of nearby projects that could lag.

Supervisor Matt Letourneau (R-Dulles) raised the issue earlier this month and won support from his colleagues.

If nearby traffic signals are not installed prior to, or along with, the interchange, Letourneau said that could impact traffic.

“The concern that I have and that we both have is related to the eastbound traffic on route 50 that is making the northern movement on route 606,” he said, explaining the request that he and Supervisor Tony Buffington (R-Blue Ridge) were making. “But what Supervisor Buffington and I would like to look at are the assumptions staff makes with regard to traffic flow.”

Letourneau also raised concerns about the way the county demographer uses regional forecasts from the Washington Metropolitan Council of Governments.

Letourneau and Buffington are concerned about traffic projections on Route 50 interchange and requested additional information

“I think there’s a chance we might be undercounting, similar to what the schools have done, the by-right growth that’s occurring on the west side,” Letourneau said. “I don’t want to under-build here given the amount of commitment it’s going to take to get the project done.” He has requested additional analysis without some of the signals included in the previous model.
