Weekend Road & Rail: Weather rules the roadwork; Metro single tracking on 5 of 6 lines

This weekend’s roadwork will be dictated by the weather. With snow and possible freezing conditions in the forecast, there is destined to be last minute changes with snow clearing and treatment becoming the focus.

Plans to the Transform 66 Outside the Beltway have already begun changing, so we’ve included those along with a few other tentative plans.

Be sure to stay tuned to WTOP and traffic on the 8s for any up to the minute changes and specifics.

Here’s what you need to know if you’re hitting the roads in the D.C. area this weekend.



Due to this weekend’s inclement weather forecast, the bridge beam installation work in Centreville as part of the Transform 66 Outside the Beltway Project began a day earlier, with a closure expected to remain the same.

This work began Thursday night, but is still on the docket for this weekend, weather permitting. All lanes of I-66 West are scheduled to be closed nightly west of Stringfellow Road between 10 p.m. and 7 a.m. over the weekend, and 10 p.m. through 4 a.m. Sunday through Tuesday. This work is to allow installation of bridge beams for a new ramp from the future I-66 Express Lanes.

Westbound I-66 traffic will be detoured using the new collector-distributor lane, Route 28, and Westfields Boulevard. The ramp to Braddock Road/Walney Road from I-66 West will remain accessible while this detour is in place.

There are always ongoing projects to Maryland roadways, most of which can be found here. Since the weather could hamper anything going into this weekend, we will look a few changes in store for this week and things that transpired this week.

There will be a new traffic shift going into place this week on MD 85 Buckeystown Pike between Crestwood Bouldevard / Shockley Drive and Sprectrum Drive as part of this ongoing rehabilitation project to replace to poorly rated bridges on I-270 (built in 1954).

The traffic shift will be necessary for crews to install underground drainage pipes and continue the widening work on northbound MD 85.

This will require the following temporary roadway closures overnight through Thursday as follows:
