After enjoying a beautiful Friday, travelers may want to get their outdoor activities done early Saturday, before rain arrives, the Capital Weather Gang says.

You might take in the Bethesda Literary Festival or the Smithsonian Craft Show. The Washington Capitals will be engaged in playoff hockey at Verizon Center on Sunday. The Nationals are at Nationals Park Friday night and Saturday and Sunday afternoons. D.C. United plays at RFK Stadium on Sunday evening.

All those events are near Metro stations, but check the weekend maintenance schedule as well as the traffic issues — such as the International Monetary Fund/World Bank meetings — that are listed below.

Metro weekend maintenance

Spring break is over. The weekend service disruptions resume on the Red and Blue lines, starting at 10 p.m. Friday and continuing through the train system’s midnight closing on Sunday.

Red Line: Buses replace trains between Rhode Island Avenue and Silver Spring. Crews will work on ties, insulators, rail fasteners, switch resurfacing and station rehabilitation at Fort Totten and Takoma. Brookland, Fort Totten’s Red Line platform and Takoma stations are closed.

During the daytime Saturday and Sunday, trains are scheduled to operate every 10 minutes between Shady Grove and Rhode Island Avenue, and between Glenmont and Silver Spring. At other times, trains will operate on their regular weekend schedules.

If you normally would use the east side of the Red Line to reach downtown D.C., consider going instead to a Green Line station, perhaps Greenbelt, College Park or Prince George’s Plaza. Or head over to the west side of the Red Line, and use Grosvenor, White Flint or Twinbrook.

The shuttle bus system works pretty well, but it will add about half an hour to normal travel times.

Blue Line: Buses replace trains between Pentagon and Rosslyn while crews work on rail ties. Arlington Cemetery station will be closed.

The line will operate in two segments: Between Rosslyn and Largo Town Center, and between Franconia-Springfield and Mount Vernon Square, using the Yellow Line bridge across the Potomac River.

Using the shuttle buses will add about 15 minutes to normal travel times. As an alternative for a trip between Virginia and D.C., consider taking either a Blue or Yellow Line train over the Yellow Line bridge to L’Enfant Plaza.

Orange Line: Trains will share a track between East Falls Church and West Falls Church while crews work on the new Silver Line extension. But Metro isn’t expecting significant delays, because this is a short section of track and the trains are operating on the reduced weekend schedule.

IMF/World Bank

This crowd probably isn’t taking Metro. The meetings jam up traffic on the streets west of the White House. Watch for these street closings and parking restrictions through 7 p.m. Sunday.

Street closings:

* 19th Street NW will be closed between G Street and Pennsylvania Avenue for that entire period.

The following streets will remain open with some temporary closures during that time:

* 18th Street NW between G Street and Pennsylvania Avenue

* 20th Street NW between G Street and Pennsylvania Avenue

* G Street NW between 18th and 20th streets

* The south side of H Street between 18th and 20th streets

Parking restrictions:

* 18th Street NW between G Street and Pennsylvania Avenue

* 19th Street NW between G Street and Pennsylvania Avenue

* 20th Street NW between G Street and Pennsylvania Avenue

* G Street NW between 18th and 20th streets

* The southern side of H Street between 18th and 20th streets

* Pennsylvania Avenue NW between 18th and 20th streets

Closing in Rock Creek Park

Rock Creek Park maintenance crews will be working on trees along Beach Drive on Friday. The drive will be closed between Broad Branch Road and Joyce Road NW from 9:30 a.m. to 2:30 p.m.

Beltway/Kenilworth Avenue bridge

On Friday night, the Maryland State Highway Administration plans to start closing lanes on the Capital Beltway near Kenilworth Avenue as part of a program to rehabilitate the bridge over the Beltway.

The closings will start with single lanes at 7 p.m., double lanes at 9 p.m. – then triple lanes at 10 p.m. After midnight, Beltway drivers may encounter complete closings for 15 minutes at a time. All lanes will reopen by 6 a.m.

SHA also will temporarily close the southbound Kenilworth Avenue ramp to the Beltway’s inner loop.

Maryland bridge inspections

The Maryland State Highway Administration has been inspecting highway bridges across the state, resulting in weekend lane closings.

From 5 a.m. to noon Saturday and Sunday, drivers may find two lanes closed on northbound Interstate 95 at Powder Mill Road.

I-70 bridges in Frederick

South Street between Franklin Street and Monocacy Boulevard near the city of Frederick is scheduled to close Friday night and reopen Sunday evening.

The work is part of Maryland’s $40 million project to widen Interstate 70 at South Street and replace the I-70 bridges. The project should be done during summer 2013.

I-95 in Baltimore

The Maryland Transportation Authority plans to close Exit 52 from northbound Interstate 95 to Russell Street. (The Orioles are out of town this weekend.) Traffic will be detoured to Exit 53, for Interstate I-395, to reach Russell Street. The exit will be closed from 8 p.m. to 5 a.m. Friday through Sunday nights while crews repair joints along the ramp.

Beltway/New Hampshire Avenue

While the rehab project continues on the Capital Beltway bridge over the Northwest Branch in Silver Spring, Maryland has begun another project at the nearby New Hampshire Avenue interchange.

It’s a bridge deck replacement for the ramp that takes traffic from northbound New Hampshire Avenue onto the Beltway’s outer loop.

To speed up the work, the ramp will be closed after the morning rush on Monday and will stay closed through mid-summer. The entire project is scheduled to be done in late fall.

While the ramp over the Beltway is closed, drivers who want to reach the outer loop will be detoured east on the Beltway to the College Park Rideshare Lot and then back onto the outer loop. This will add about 15 minutes to normal travel times.

As the project advances, Beltway drivers in that area should watch for single, double and triple lane closings and lane shifts from 10 p.m. to 5 a.m. Sundays through Thursdays.

DC 295 lane closings

The District Department of Transportation plans to close the right lane and shoulder on northbound DC 295 between Benning Road and Nannie Helen Burroughs Avenue from 9:30 a.m. and 3:30 p.m. Monday and Tuesday for a work zone.
