WASHINGTON - The City of Alexandria is implementing left-turn restrictions after a 2011 study of the Washington Street corridor showed an elevated accident rate for vehicles turning left during HOV hours.

The elevated accident rate occurred most frequently between 7 and 9 a.m. and between 4 and 6 p.m. Protected left turns, where vehicles can turn left on a green traffic signal arrow, have been added for southbound vehicles turning left at Washington and Wythe streets and at Washington and Princess streets during the morning HOV hours. Similar protected left turns have been added at Washington and Wythe streets and at Washington and Queen streets during the evening HOV hours.

Left turns are prohibited Monday through Friday from 7 to 9 a.m. at the following intersections:

• Southbound Washington Street at Pendleton Street
• Southbound Washington Street at Oronoco Street
• Southbound Washington Street at Princess Street
• Southbound Washington Street at Cameron Street
• Southbound Washington Street at Duke Street
• Southbound Washington Street at Wolfe Street

Left turns are prohibited Monday through Friday from 4 to 6 p.m. at the following intersections:

• Northbound Washington Street at Pendleton Street
• Northbound Washington Street at Oronoco Street
• Northbound Washington Street at Cameron Street
• Northbound Washington Street at Duke Street
• Northbound Washington Street at Wolfe Street

The city's Traffic and Parking Board, who approved the study in November 2011, believe the number of accidents resulting from left turns will decrease with these restrictions. All other existing regulatory restrictions will remain in effect.

The restrictions will go into effect on Wednesday, Oct. 24.

WASHINGTON - This weekend features major events including the The Army Ten Miler, the Best Buddies Challenge D.C. bicycle event and the Women in Military Service for America 15th Anniversary Vigil.

Part of B/W Parkway overnight closure extended all day Saturday

This weekend the Baltimore Washington Parkway is closed northbound Saturday at the West Nursery Road overpass north of BWI Thurgood Marshall Airport because of a problem with a bridge project.

The Maryland State Highway Administration says drivers should use I-95, Route 1 or Route 29.

The project involves replacing the two West Nursery Road bridges over the parkway. While removing the northbound deck early this morning, the load shifted and cannot be wheeled away.

The bridge deck is being re-secured and will be tested to make sure that it's safe late Saturday. That decision will come later Saturday or Sunday morning.

Lane closures will begin again Saturday night at 9 p.m. with the full closure in place by 11 p.m. If you are traveling to the airport from the south you WILL be able to exit at I-195 to the airport but traveling from the north the last chance to exit will be 1-695 the Baltimore Beltway. If you continue to West Nursery Road you will be detoured along the West Nursery Road ramps. In anticipation of delays you may want to use I-95, MD 29 or U.S. Route 1 as alternate north-south routes. I-97 is also an option from points east.

I-270 Frederick County paving

On I-270 between Rt 80 Urbana and Rt 109 Hyattstown, one lane in each direction will be closed from 9p.m. Friday until 7 a.m. Saturday. This means that in that stretch I-270 will have only one lane running in each direction.

Rockville Pike resurfacing

Southbound Rockville Pike Route 355 near Tuckerman Lane, 2 left lanes will be closed starting Friday at 9 p.m. until Saturday at 2 p.m. for resurfacing

Route 50 John Hanson Highway paving

Friday night at 11 p.m., three lanes will be closed on Route 50 eastbound between MD 197 Collington Road and Rt 3/301 in Bowie. Lane closures will continue throughout the weekend until work is completed by 8 a.m. Sunday morning.

Dulles Access Road westbound full closure

The Dulles Access Road westbound will be closed between Wiehle Avenue and Reston Parkway from 9 p.m. to 11 p.m. Friday night and then again from 3 a.m. to 5 a.m. Saturday morning for pedestrian bridge work.
