There are two big projects in the works that are scheduled to continue into this weekend as part of the Transform 66 Outside the Beltway Project.

This weekend will see the bridge beam installation continue at the I-66/I-495 Interchange with lane and ramp closures planned. The overnight demolition of the old Gallows Road Bridge over I-66, which has been ongoing all week, is expected to continue into Saturday night.

Maryland

As we head into the holiday travel season, it’s worth mentioning the new project in Frederick. The Maryland Department of Transportation State Highway Administration (MDOT SHA) will continually be working on the northbound US 15 (Catoctin Mountain Highway) bridge over MD 77 (West Main Street) and Hunting Creek in Thurmont in a bridge rehabilitation project, which will reduce travel to one lane for the next six to eight months.

They are currently in phase two of this work replacing the original 1957 structure.

There is also the lane expansion project on southbound I-270 between MD-121 Clarksburg Road and MD-109 Old Hundred Road closing multiple lanes during off-peak and overnights daily, Sunday through Thursday, until the end of the year.

In Montgomery and Prince George’s Counties there will continue to be various road construction related to the Metro Purple Line Project. The new project has begun on Georgia Avenue and Bonifant Street for waterline replacement. During off-peak times over the next three weeks, there will be lanes restricted, weather permitting.

There is ongoing utility relocation on MD 201 Kenilworth Avenue between Campus Drive and MD 410 Riverdale Road during off-peak times restricting lanes controlled by flaggers, which will continue during the weekend as needed.

DC

In a heads up this weekend for travelers of the Memorial Bridge, US-50 and access into Arlington National Cemetery, there is the annual Wreaths Across America event opening to families with a bigger event planned for the public next weekend.

The District Department of Transportation (DDOT) will have the I-295/DC-295 Corridor Project continual closing lanes and ramps through the weekend. Be sure to check the link for specific times and closures on I-295/DC-295 from Laboratory Road to Nannie Helen Burroughs Avenue.
