The Capital Weather Gang predicts a wonderful week for travelers. The big road work projects are in full swing, but not all drivers are encountering serious delays. For example, the lane restrictions at the New York Avenue Bridge have not yet produced the severe delays we expected. But the northbound span of the 14th Street Bridge does get very congested south of the work zone.

And be careful using the ramp from the southbound span onto the northbound George Washington Parkway.

The Washington Nationals are out of town until Friday, then they’ll be home at Nationals Park near M and South Capitol streets through May 17.

Here are some of the traffic hotspots.

Constitution Avenue

Here’s the weekly schedule from the National Park Service for the reconstruction of Constitution Avenue.

Weekdays: From 5:30 a..m to 3:30 p.m., expect up to two westbound lanes and two eastbound lane to be closed on Constitution Avenue between 23rd and 20th streets NW. The location of the lane closings may change daily. Lane closures will be set up before the morning rush and removed at the end of the day. Curb lanes may remain closed overnight for safety.

Weeknights: From 7 p.m. to 5:30 a.m., expect up to three westbound lanes or three eastbound lanes, or both, to be closed on Constitution Avenue between 23rd and 20th streets. The locations may change daily. Curb lanes may remain closed for safety.

Weekend work: From 7 a.m. to 5 p.m. Saturday, expect up to two westbound and up to two eastbound lanes to be closed between 23rd and 20th streets. Curb lanes may remain closed for safety.

Rock Creek Parkway

Here’s what the National Park Service says is scheduled between P Street and Beach Drive this week.

The project involves installing new inlets and pipe runs along both sides of Rock Creek Parkway, pouring light pole foundations along the parkway, installing underground conduit for the new street lights, installing new timber guardrail along the southbound side of the parkway and placing new curbs and gutters along the northbound side of the parkway.

These are the weekday traffic restrictions.

Cathedral Avenue, south of Woodley Road: Southbound closed all the time. Northbound open all the time.

Beach Drive: Both lanes open all the time.

Rock Creek Parkway: The southbound side will have a temporary lane closure during non-rush hours. The northbound side will have a lane closed all the time to install new concrete curbs and gutters.

Shoreham Drive: From 7 to 9:15 a.m., only one lane will be open southbound. The northbound side is closed. From 9:15 a.m. to 7 o’clock the next morning, only one lane will be open northbound. The southbound side is closed.

Maryland lane closings

These are some of this week’s lane closings for Maryland State Highway Administration projects.

Rockville Pike between First Street and Templeton Place: lane closings with flaggers from 9 p.m. to 5 a.m. each night through Thursday night.

University Boulevard between Arcola Avenue and Route 29: lane closings from 9 a.m. to 3 p.m. weekdays.

Georgia Avenue between New Hampshire Avenue and Queen Elizabeth Drive: lane closings with flaggers from 8 p.m. to 5 a.m. each night through Thursday night.

Norbeck Road and Glenallan Avenue: lane closings from 9 a.m. to 3 p.m. weekdays and 7 p.m. to 9 p.m. weeknights.

Powder Mill Road between University Boulevard and Cherry Hill Road: lane closings from 9 p.m. to 5 a.m. through Thursday night.

Kenilworth Avenue between Tuxedo Road and Frolich Lane on the interchange ramps: lane closings from 9 p.m. to 5 a.m. through Thursday. Flaggers at Tuxedo Road.

Humpback Bridge

The reconstruction of the bridge on the George Washington Parkway near the 14th Street Bridge is scheduled to be done in late spring. Here’s what’s going on this week.

Work continues on the bridge median, and there’s a work zone in the middle of the parkway over the bridge. Also the ramp from the southbound 14th Street Bridge to the northbound parkway still does not have the acceleration lane fully open. Be careful merging.

Metrobus meetings

Metro and transportation agencies in the District and Maryland have scheduled two public meetings this week about their Metrobus A and Y Line studies to improve bus service along Martin Luther King Jr. Avenue in Southeast Washington and Georgia Avenue in Maryland.

The sessions continue a string of efforts to improve Metrobus service on some of the most heavily used lines. They are not related to the public hearings on Metro’s operating budget for fiscal 2012, coming up this month.

The session on the future of the A Line is scheduled for 5 to 7:30 p.m. Tuesday at Savoy Elementary School, 2400 Shannon Pl. SE. The session on the Y Line is set for 6 to 7:30 p.m. Thursday at the First Baptist Church of Wheaton, 10914 Georgia Ave.

Connector/Notley Road

The Maryland State Highway Administration this weekend paved the new bridge on Notley Road in Montgomery County over the future route of the Intercounty Connector. Later this spring and summer, the detour roadway will be completely removed and new curbing and sidewalk completed along northbound Notley Road.

The portion of the connector project in that area, between Georgia Avenue and Route 29, is about 75 percent done.

Beltway/Telegraph Road

The Wilson Bridge project will close some lanes and shift traffic around the Telegraph Road interchange this weekend to prepare for the new ramp opening from Telegraph Road South to North Kings Highway and for roadway construction.

The opening of the ramp will permanently eliminate the left turn from Telegraph South onto North Kings Highway, lengthening green-light time for Telegraph Road travelers.

For southbound drivers on Telegraph Road, the turn to North Kings Highway will be the first right after crossing the Cameron Run Bridge, while the turn to Huntington Avenue will be the second right. The new ramp is scheduled to be open by 5 a.m. May 16, but the weekend work is likely to cause local traffic delays, and it would be a good idea to use alternative routes.
