Northern Virginia soon will receive a $350,000 grant to study ways of using transit to alleviate traffic along the congested Route 7 corridor.

The Federal Transit Administration awarded the Northern Virginia Transportation Commission the money about two years ago to study a "range of visionary high-capacity transit solutions" along the road from the King Street Metro station to Tysons Corner in Fairfax County. But the earmarked money is only now being released.

Specifically, the study will focus on ways of linking transit along the corridor to the Silver Line now under construction.

Separately, a task force last year studied ways of alleviating traffic on the route where it extends into Loudoun County.
