Travelers in the D.C. area will have to deal with this rain through Wednesday, the Capital Weather Gang says, but then we’ll have sun and warmth into the weekend.

The rain and thunder may slow some of the road work listed below, though many work zones remain active. Metro crews now work on maintenance pretty much around the clock, outside of rush hours. That leads to midday and late night delays on many lines. See Monday’s Tom Toles cartoon on Metro service.

The Nationals will be playing all week at Nationals Park, leading to a weekend series with the Orioles that’s likely to draw a lot of traffic from the north. D.C. United play at 7:30 p.m. Wednesday at RFK Stadium, then again on Saturday at 7:30. The Wednesday game is Bike to RFK Stadium Night.

At noon Monday, join me for our weekly online chat about getting around the D.C. region.

Southeast-Southwest Freeway

On the west side of the Anacostia River near the 11th Street Bridge project, the District Department of Transportation has permanently closed the Eighth Street exit ramp from the westbound Southeast-Southwest Freeway.

This is the ramp for freeway traffic coming from Pennsylvania Avenue and heading for the Marine Barracks and Eighth Street SE. The exit to Eighth Street from the inbound 11th Street Bridge will remain open.

D.C. bridges, ramps

The District Department of Transportation plans single lane closings on many bridges and ramps from 10 a.m. to 3:30 p.m. weekdays for painting and maintenance.

Monday: 35th Street NE over East Capitol Street

Tuesday: Portland Street over South Capitol Street, New York Avenue over North Capitol Street

Wednesday: South Capitol Street over Oxon Run, ramp over C Street near RFK Stadium.

Thursday: Ramps over pedestrian walk near RFK Stadium.

Friday: Park Road over Piney Branch Parkway in Rock Creek Park,

Fairfax County Parkway/Fair Oaks

Look for continued delays and detours at the intersection of the Fairfax County Parkway and Fair Lakes Parkway this week, the Virginia Department of Transportation said.

The work that began last week is scheduled to continue. From 9 p.m. to 5 a.m. weeknights, workers will be placing beams for the bridges that will carry traffic over Fair Lakes Parkway and Monument Drive.

Drivers heading to the Fairfax County Parkway from Monument Drive will be detoured to West Ox Road.

The rebuilding of the intersection is scheduled to be done in 2013. It will widen more than three miles of the Fairfax County Parkway and separate local and parkway traffic through this intersection area.

Fairfax Parkway in Springfield

The Virginia Department of Transportation will be paving the Fairfax County Parkway in Springfield during the day this week, including part of the afternoon rush hours.

From 9 a.m. to 5 p.m. weekdays, paving will be underway on both sides of the parkway between the Pohick Road and Rolling Road overpasses. Drivers will encounter alternating single-lane closings.

During the same hours, paving also will be underway on the adjacent Franconia-Springfield Parkway East from the Rolling Road overpass to the Accotink Creek bridge.

Dulles Access Highway

Drivers heading east from Dulles International Airport late at night this week will find the Dulles Access Highway closed. The eastbound traffic will be diverted onto the Dulles Toll Road and drivers will pay the $1.50 toll at the main toll plaza.

It’s very unusual for traffic to be diverted from the free airport access road to the toll-paying lanes. But the Dulles Metrorail project announced that the closing, which began this week, is necessary to complete the last part of the flyover bridge that will bring the track for the new Silver Line out of Tysons Corner and into the middle of the Dulles highway.

The closed portion of the Dulles Access Highway will extend from Centreville Road to just past the main toll plaza. The closing will be imposed from 9 p.m. to 5 a.m. Sunday through Thursday nights and from 9 p.m. to 7 a.m. Friday night.

Sherman Avenue NW

This week, the District Department of Transportation is going to temporarily shift the traffic pattern on Sherman Avenue NW between Fairmont and Girard streets. Traffic will be moved to the east side of the avenue to make room for reconstruction the west side that’s part of the Sherman Avenue Streetscape project.

Drivers will have one northbound and one southbound through that area during the construction.

Bike to Work Day

More than 10,000 commuters are likely to participate in Friday’s annual Bike to Work Day. The regional event gives them a chance to experience a cycling trip to work without the anxiety of doing it solo.

Participants will gather into convoys at 58 designated pit stops and make their voyages in the company of experienced guides. Register online and get details about the gathering places at

Metro weekend maintenance

I’ll have the single-tracking schedule for you later, but there is one line split scheduled for this coming weekend, from 10 p.m. Friday through the rail system’s midnight closing on Sunday.

Orange Line: Buses replace trains between East Falls Church and West Falls Church. Crews work on switch installation for the Silver Line extension and tie replacement.
