The week ahead for traffic, transit

After a beautiful day Monday, travelers may encounter some showers in the D.C. area, according to the Capital Weather Gang. Bikers and walkers should note that the humidity is going to rise as the week develops. This is high season for road projects. Both sides of the Capital Beltway in Virginia are particularly busy. In Maryland, the Intercounty Connector project has some limited traffic impacts, but it's the smaller projects that are likely to cause delays.

Change at D.C. intersection
The busy intersection at Seventh and H streets NW in downtown Washington is getting a makeover. On Wednesday, pedestrians will get a light cycle of about half a minute in which they can cross in any direction, including diagonally. The lights for all vehicles will be red during that cycle. At no time will drivers be allowed to make a turn at that intersection. Traffic control officers will be on hand for a couple of weeks to enforce the new rules and the new crossing pattern.

Norbeck Road/Intercounty Connector
Traffic on Norbeck Road (MD Route 28) between Baileys Lane and Wintergate Drive has shifted to a temporary roadway. This makes room for construction of a permanent bridge over the Intercounty Connector. Watch for a temporary traffic signal.

ICC at I-95
From midnight to 5 a.m. each night through Thursday night, Interstate 95 might be shut for 15 minute intervals because of construction in the Intercounty Connector work zone.

South Dakota bridge
The District has opened a new $7 million bridge that carries South Dakota Avenue over the CSX tracks in Northeast Washington. The bridge, just northwest of the Bladensburg Road intersection, is used by 40,000 vehicles a day. It replaces three spans with a single span.

The project began in 2007 and was originally scheduled to take two years. But the District Department of Transportation said it discovered design flaws that required a halt in the project until modifications could be made.

Douglass Bridge repairs
The District Department of Transportation is doing some repairs on the Frederick Douglass Bridge, which takes South Capitol Street over the Anacostia River. Truck loads are restricted to 10 tons, and trucks will be limited to using the center lanes, as they are now. The new weight limit is scheduled to remain until Sept. 1.

Most of the repair work will be done at off-peak hours. There will be lane closings during those hours. This project is part of the bridge maintenance and repair that began in 2007.

Gallows Road/Beltway
Traffic has shifted to the new bridge over the Capital Beltway at Gallows Road. This work is part of the High Occupancy Toll lanes project, which is widening the western side of the Beltway in Virginia and all its bridges. For the next year to 18 months, drivers will have one southbound lane on the Gallows Road bridge rather than two, but there will be two lanes northbound toward Inova Fairfax Hospital. VDOT expects there will be 10- to 15-minute delays at the bridge during the afternoon rush.

Dulles Rail project
The entrance ramp from southbound Route 123 to the southbound Capital Beltway (outer loop) will close between 11 p.m. and 5 a.m. on Monday through Wednesday nights. Crews will be installing a large reinforced iron cage for pier construction in that area.

MD 201 Bridge over Beltway
Watch for lane closings in both 201 and the Beltway during this bridge repair project. The lane closings can occur during off-peak periods both day and night. The shoulders are closed on both sides of the Beltway.

Rockville Pike at Randolph/Montrose roads
There will be single lane closings at off-peak periods both day and night for the interchange construction project.

University Boulevard
There's a paving project underway between Arcola Avenue and Veirs Mill Road. Watch for lane closings at midday and overnight.

Metro night delays
Red Line:After 10 p.m. each night through Thursday, add 20 minutes to a trip between Grosvenor and Medical Center. Metro is replacing rail fasteners.

After 10 p.m. each night through Thursday, add half an hour to a trip between Rhode Island Avenue and Fort Totten. Metro is working on the surface underneath the tracks in that area.

Blue/Yellow lines: After 11 p.m. each night through Thursday, add at least half an hour between Braddock Road and Pentagon City. Metro is replacing rail fasteners.

Green Line: After 10 p.m. each night through Thursday, add at least 20 minutes between Branch Avenue and Suitland. Metro is replacing rail fasteners.
