The Washington Post » The toll on Interstate 66 inside the Capital Beltway reached $46.50 for a solo driver during the Tuesday morning rush, just below a record of $47.25 set last month. For much of the morning Tuesday, there were no major crashes in the D.C. region, but a heavy volume of commuters created delays on several highways in the Washington area. The toll reached its peak about 8:30 a.m.
