Weekend Road and Rail: I-66 work extends to Beltway stops, Metro work reprieve

Weather permitting, there are planned stops for Interstate 66 and the Capital Beltway in the overnight hours, plus closures related to South Capitol Street and Interstate 295/D.C. 295 corridor work. There’s upcoming Interstate 70 improvement work in Maryland and Metro maintenance will cause single tracking on three lines.

Here’s what you need to know.

Roadwork

Maryland

In Howard County, the Maryland Department of Transportation State Highway Administration will begin a project next week to improve the driving surface along westbound Interstate 70.

Starting Monday, March 21, crews will work overnight on the roadway between the westbound U.S. 40/Baltimore National Pike merge ramp and Md. 97/Hoods Mill Road.

As part of this $4.6 million project, crews will remove the top layer of the roadway, repairing potholes and depressions to smooth out the surface. Crews will work 8 p.m. to 5 a.m. Sunday night through Friday mornings.

During work hours, motorists can expect single lane closures on westbound I-70 with work expected to last until July. This includes the following ramp closures:

  • Exit ramp to Md. 32
  • Southbound Md. 32 ramp to westbound I-70
  • Exit ramp to Md. 97

Motorists will be detoured to the next interchange and use eastbound I-70 to access Md. 32 or Md. 97 when westbound I-70 exit ramps are closed.

No major work changes are listed for this weekend. Other ongoing Maryland roadway projects can be found here. For the ongoing Purple Line work between Prince George’s and Montgomery counties, see the project’s website.



Virginia

A big part of the Transform 66 Outside the Beltway Project this week has been the bridge beam installation on I-66 near the Manassas area, reducing travel to a single lane overnights. This will continue through Sunday morning, weather permitting.

So far, the schedule has seen I-66 reduced to a single lane in each direction around 10 p.m. for about one mile. This closure is for continued bridge beam installation for a new access ramp to the future I-66 Express Lanes.

I-66 East will be closed with two-way traffic running on I-66 West with the ramp from Route 234 Business North and South to I-66 East will also be closed and detoured.
