I-66 lanes to close overnights

Construction of the Dulles Metrorail extension is scheduled to close the westbound lanes of Interstate 66 at the Dulles Connector Road overnight Saturday and Monday.

The shutdowns will clear room for construction crews to continue building the large concrete structures that will straddle the road between piers. These structures, called "straddle bents," will support the new rail line near its merge point with the Orange Line.

The original schedule called for a closing Friday night, but that was postponed. Instead, drivers out late Saturday on I-66 heading for destinations west of Arlington should watch for the closing to begin at midnight.

Through traffic will be detoured onto the westbound Dulles Connector Road, then to Route 123 south toward Tysons Corner, to a right turn onto the ramp to the Capital Beltway's outer loop, toward Richmond. Drivers can then rejoin I-66 from the Beltway.

To avoid the closure, drivers bound for destinations inside the Beltway could get off I-66 before the I-66/Dulles Connector Road split and take local westbound roads. For example, traffic bound for the Broad Street (Route 7) and Idylwood areas could exit before the detour and use Route 29/Washington Street to connect with Broad Street.

The closings will be lifted by 5 o'clock the next morning.

Wonder how many people didn't read the traffic blogs and were suddenly redirected on Sat. night! I went through there Friday on my way to Arlington during evening rush hour and there was this amazing back up going east towards DC as opposed to west like you would think rush hour traffic would be heading for the most part. West was just whizzing by! Interesting construction to watch though!
