Weekend Road and Rail: Bridge work, Beltway and I-66 projects; Metro maintenance on all lines

Weekend Road and Rail featuredAfter a long holiday hiatus, work is expected to ramp up again on I-66, the District bridges, the Beltway and on the Purple Line in Maryland. Weather has been an issue all week, be sure to stay tuned for the latest.

As a reminder, all work is weather dependent, be sure to stay tuned to WTOP and traffic on the 8s for any up to the minute changes. And, as always, be sure to call the Traffic Center with all updates at 866-304-WTOP.

Here is what’s planned.



As the New Year kicks off, we are definitely off to a bang weather-wise! And of course, the Transform 66 Outside the Beltway Project is set to continue between the Beltway and Gainesville to include the 12 interchanges along that 22-mile stretch. For a look into what to expect for the New Year, be sure to check out the VDOT project page for an overview.

In Prince George’s County, the I-95/I-495 Beltway bridges over Suitland Road and the Suitland Parkway, are in the process of the replaced in two locations. The two projects are both considered approximately 90% completed. This means there’s still work underway with off-peak lane and shoulder closures possible through this year.

The Maryland Department of Transportation State Highway Administration (MDOT SHA) work includes new steel girder bridges with 25-foot by 6-inch-wide inside shoulders, allowing for possible future Beltway widening. Each new one-span bridge will be raised to provide additional under clearance with new lighting and stormwater management facilities. To stay up to date on this work and scheduling check out the MDOT SHA Project Portal.

Montgomery and Prince George’s Counties will see the return of the Metro Purple Line Project. This week, underground utility relocations began on Wayne Avenue near the Sligo Creek Parkway. There will be work on weekends continuing through April, which could mean lane and sidewalk closures through the area.

And, beginning on or about Jan. 13, crews will begin underground utility relocations on the north side of the CSX tracks between 16th Street and Fenwick Lane. This work will also be taking place daily through the end of January. For all specifics relating to this project, be sure to check the Purple Line construction website.

In St. Mary’s County, crews continue to resurface MD 235 Three Notch Road between Jacksons Road and Great Mills Road with single lane closures daily, Sunday to Thursday, through the fall.
