It’s a holiday for federal employees, but many of us had to make the trek to the office on what the Capital Weather Gang is calling a gem of day. However, rain is going to roll in later in the week, slowing down commutes.

Here’s a look at some of the other issues that may affect your travels on Columbus Day and the rest of this week.


The transit authority is taking advantage of the holiday weekend to d o needed track work on the Green and Yellow lines, and crews assigned to the Dulles rail extension are working on the new line’s connection with the existing system.

This means three stations are closed today: Shaw, U Street and Columbia Heights. They are scheduled to reopen at 5 a.m. Tuesday. On the Orange Line, East Falls Church and West Falls Church are open, but there is no rail service between the two. Free shuttle buses are bridging the gap, but you should add 20 to 30 minutes to your travels.

Metro has suggested that some Green Line passengers can use the Red Line, which isn’t affected by track work, as an alternative.

Metrorail and Metrobus are both on Saturday schedules today. Other transit agencies are also operating on special schedules.

Dulles Toll Road Closure

The Dulles Toll Road (Route 267) and Dulles Access Highway will close over night for up to 15 minutes at a time as crews replace power lines. The closures will occur between Route 7 and Trap Road between midnight and 1 a.m. Officials with the Dulles Metro project said there will be no detour and police will be on site.

Capital Beltway in Virginia

The right lane of the outer loop is scheduled to close overnight Wednesday and Thursday for work associated with the Wilson Bridge project.

Crews plan to close the lane at 9 each night between the Eisenhower Avenue Connector and Telegraph Road, with the middle lane also closing at 11 p.m. Lanes are scheduled to reopen by 5 a.m.

Two right lanes of the outer loop are scheduled to close at 11 Friday night. Crews plans to reopen the middle lane by 6 a.m. Saturday but will close it again at 11 p.m. All lanes should be reopened by midday Sunday.

This work has been rescheduled for the week of Oct. 16: Three right lanes of the outer loop are scheduled to close from Dominion Drive to the Chain Bridge Road exit on from 9:30 p.m. to 5 a.m. Wednesday through Friday for work associated with the Dulles rail project.

Horner Road commuter lot

Virginia State Police plan to begin a targeted enforcement effort at the Horner Road commuter parking lot on Prince William Parkway. Authorities said they are focusing on vehicles parked outside of designated areas and creating traffic hazards.

Signs are scheduled to go up on Tuesday alerting people to the enforcement, and police will be placing fliers on vehicles that are illegally parked. Authorities said they will begin issuing tickets on Monday, Oct. 17, and towing vehicles in some cases.

Targets will include:

• Vehicles parked in areas posted or marked “No Parking.”

• Vehicles parked in landscaped areas not intended for parking.

• Vehicles parked in a travel lane and obstructing traffic. (Officials said these cars will be ticketed and towed).

District bridge inspections

The District Department of Transportation will begin conducting bridge inspections beginning Tuesday. Drivers should be alert for lane closures in the areas.

• Pedestrian bridge near Nash Street NE over Kenilworth Avenue. be alert for closures on Kenilworth. Inspection will take place between 10 a.m. and 3 p.m. Tuesday.

• Southwest Freeway over Fourth Street SW. Expect alternating lane closures between 10 a.m. and 3 p.m. Thursday and Friday.

Nannie Helen Burroughs Avenue

The District Department of Transportation plans to shift traffic to the south side of Nannie Helen Burroughs Avenue NE between Minnesota Avenue and Hayes Street on Wednesday.

Officials said one lane will remain open in each direction.

Dr. Gridlock is away

Robert Thomson is away, so there won’t be a chat with Dr. Gridlock today. He will return on Monday. Meanwhile, you can peruse past chats about traveling around the Beltway and beyond.

Fairfax County Planning Commission Tysons Corner Committee

The committee is scheduled to meet at 7 p.m. Wednesday in conference rooms 2 and 3 at the Government Center, 12000 Government Center Pkwy. Items on the agenda include:

• An update on development applications in Tysons Corner.

• A discussion on cost sharing (government vs. private).

• A review of potential sources of funding.

Martin Luther King Jr. Memoria l dedication

The dedication of the King monument is set for this Sunday, after Hurricane Irene forced a delay in August. Plans and expectations have been scaled back, but the event is still expected to draw thousands to West Potomac Park and the National Mall. Dr. Gridlock has a useful guide for getting to the site.

Metro has postponed major track work for this coming weekend, and the transit authority plans to begin rail service at 5 a.m., with extra capacity to accommodate the crowds.
