Virginia’s highway panel on Thursday pared nearly $900 million in road and transit projects planned over the next six years, bringing the state’s transportation ambitions in line with its free-falling tax revenues.

The cuts scuttle major Northern Virginia interchange upgrades, road widenings and bridge work, most of which are in advanced planning stages. They include the $14 million bridge replacement over Little Rocky Run in Fairfax County, and an interchange revamp at the crossing of Glebe Road and Route 50 in Arlington County.
