The first couple of days will be a bit on the cool side this week, the Capital Weather Gang says, but then the temperatures will rise into the 60s. The best chances of rain come on Monday and Thursday.

There will be some Metrorail crowding downtown each night through Thursday for Capitals and Wizards games at Verizon Center. And Metro is doing some track work that will cause delays. The road work schedule is limited, but you will find all the big projects are active at off-peak hours.

Metro weekday maintenance

The transit authority plans off-peak work on three lines this week.

Blue Line: From 10 a.m. to 2 p.m. weekdays, trains will share a track between Foggy Bottom and Arlington Cemetery. Add about 10 minutes to normal travel times.

After 10 p.m. Monday through Thursday, trains will share a track between Eastern Market and Stadium-Armory. Add five to 10 minutes to normal travel times.

Orange Line: From 10 a.m. to 2 p.m. weekdays, trains may be delayed briefly while going through Rosslyn, because trains on the Blue Line will be sharing a track. Add about 10 minutes to normal travel times, Metro says.

After 10 p.m. Monday through Thursday, trains will share tracks between East Falls Church and West Falls Church, and between Eastern Market and Stadium-Armory. Add five to 10 minutes to normal travel times.

Green Line: From 10 a.m. to 2 p.m. weekdays, trains will share a track between College Park and Greenbelt. Add about 10 minutes to normal travel times.

Constitution Avenue NW

Watch for closings of the eastbound curb lane on Constitution Avenue NW between 17th and 15th streets from 5:30 a.m. to 7 p.m. weekday. Crews working on the National Park Service road rehabilitation project will be installing a fence. Parking will be restricted in the curb lane.

Beltway/Northwest Branch bridge

The Maryland State Highway Administration continues the bridge renovation on the Capital Beltway between University Boulevard and New Hampshire Avenue. (This is the one with the speed camera.)

All lanes are open during peak periods, but watch for single lane and double lane closings between 8 p.m. and 5 a.m. Sunday through Thursday nights. Drivers may find three lanes closed from midnight to 5 a.m. weeknights.

Beltway/Landover Road

The Landover Road (Route 202) bridge over the Beltway also is under repair by the Maryland State Highway Administration. Watch for single lane closings from 9 a.m. to 3 p.m. weekdays.

Arlington Memorial Bridge

The center lanes in both directions on the Memorial Bridge will be closed from 9:30 a.m. to 2:30 p.m. Monday. For this period between rush hours, drivers will need to use the two right lanes.

Workers will be installing metal plates in the center lanes as part of a rehabilitation project.

Beltway/Telegraph Road

The Wilson Bridge project continues to work on the Capital Beltway lanes and the Telegraph Road interchange west of the bridge. From 9:30 a.m. to 3 p.m. Monday, the outer loop exit ramp to northbound Telegraph Road will be closed. Drivers should follow the detour from the Eisenhower Avenue ramp to northbound Stovall Avenue to westbound Pershing Avenue.

Metrobus changes

Metro is changing the start times for some of its morning bus trips starting Monday. The transit authority says the adjustments respond to requests from school officials, and also reflect the realities of traffic congestion. These buses are used by many students attending Deal Junior High School and Wilson High School in Northwest Washington.

As of today, Metrobus routes D31, D32, D33, D34 and W45 will leave their starting points 10 minutes earlier for morning trips.

Metro fare increase hearings

The last three of the Metro board’s six hearings on the proposed fare increases will be held this week. Each will begin at 7 p.m., but will be preceded by an hour-long open forum at which people can talk about any topic related to Metro operations. Here are the dates and locations of the upcoming sessions.

Monday: Washington Lee High School Cafeteria, 1301 N. Stafford St., Arlington

Tuesday: St. Columba’s Episcopal Church, 4201 Albemarle St. NW, the District

Wednesday: First United Methodist Church, 6201 Belcrest Rd., Hyattsville

Rock Creek Park

From 9:30 a.m. to 2:30 p.m. Tuesday and Wednesday, maintenance crews are scheduled to work on trees and the roadway along Beach Drive in Rock Creek Park. During those hours, Beach Drive will be closed between Sherrill Drive and Wise Road.

Dulles Metrorail project

Construction of the bridge for the Dulles Metrorail line in the median of Leesburg Pike (Route 7) in Tysons Corner is about to begin its final phase. The big yellow and blue truss that puts the pieces in place will cross over the eastbound lanes of Route 7.

Workers are about to temporarily shift the eastbound lanes about 30 feet to the right, so they won’t be working above traffic. This is scheduled to begin overnight Thursday.

To set up the lane shift, the right through lane from Jarrett Valley Drive to the exit ramp from the eastbound Dulles Access Highway will be closed from 9 p.m. to midnight. From midnight to 5 a.m., the left through lane will be closed in same area.

Drivers may encounter total closings of eastbound Route 7 for up to 15 minutes during the traffic switch.

Beginning overnight Thursday, the ramp from the eastbound Dulles Access Highway to westbound Route 7 will be closed.

The lane shift and the ramp closing will remain for about two weeks. Then the eastbound lanes of Route 7 will shift back to the current configuration, and the ramp will reopen. The truss will then move westward.

During the two weeks of the ramp closing, drivers who want to reach westbound Route 7 from the eastbound Dulles Access highway should take the exit to eastbound Route 7 instead, then make a U-turn at Spring Hill Road onto westbound Route 7.

Baltimore-Washington Parkway

On Wednesday, the National Park Service plans to close the northbound left lane of the Baltimore-Washington Parkway near the Capital Beltway interchange from 9:30 a.m. to 2:30 p.m. while crews block off the left shoulder with jersey barriers.

Workers then will begin repairing a sinkhole on the left shoulder, a project that will take about two weeks.
