The work zone that has been blocking eastbound traffic on the left side of the Dulles Toll Road near the Capital Beltway interchange is scheduled to be removed next week, well ahead of the original time estimate.

That should ease the extra congestion that eastbound drivers have encountered since spring as they approach the Beltway interchange north of Tysons Corner.

It’s one of two improvements slated for this coming week as the high-occupancy toll lanes project advances. The other is the opening of the new flyover ramp from eastbound Interstate 66 onto the right side of the Beltway’s inner loop. But unlike the flyover ramp, which is brand new, the change at the toll road represents a return to what commuters had before the work zone was created.

Still, this should improve travel conditions in one of the most-complained about work zones in the D.C. region. The left-side work zone has squeezed traffic in an area that didn’t need any help to be congested.

During the summer, project managers took some steps they hoped would ease the difficulty somewhat, but they’re working in a very restricted area, and the results were limited.

Under the original timetable, it seemed likely the work zone would remain in place till spring. But project managers now expect to restore the lane on Tuesday morning.

This is what’s scheduled to happen first: From 9:30 p.m. Monday to 5 a.m. Tuesday, the eastbound Dulles Toll Road at the Beltway will be closed to prepare for the reopening.

Overnight detours will be set up. Eastbound traffic will be directed to take the Beltway’s outer look (I-495 south) to Exit 46B for northbound Chain Bridge Road. There, they will follow signs back to the eastbound toll road.

If the overnight work goes according to schedule, then by 5 a.m. Tuesday, all lanes on the eastbound will be reopened, and as they were before the construction began.

If bad weather cancels the overnight work, it will be rescheduled for Tuesday night, and the reopening would occur Wednesday morning.
