    Drivers who take Interstate 395 from Washington toward the Capital Beltway should be prepared for afternoon delays because of an emergency work zone near Lincolnia, Virginia. 
    South of Duke Street, the ramp from the southbound general purpose lanes of I-395 onto the 395 Express Lanes (and 95 Express Lanes) is expected to remain closed through next week. The Virginia Department of Transportation and the operator of the Express Lanes, Transurban, are assessing what they call "pavement issues" that are affecting the ramp.  
    The left exit, known as the "Turkeycock" slip ramp, was closed for a similar reason a couple of years ago. The cavity beneath the driving surface will require time-consuming repairs. 
    Southbound drivers on the I-395 HOV lanes past Duke Street will still be able to transition onto the toll-free main lanes as usual. 
    Another slip ramp was permanently closed near the Pentagon earlier this week. The scheduled closure is a part of construction to convert the HOV lanes into E-ZPass-only lanes.
    Following the rainiest year on record, storm water pipes across the region are failing. Recent repairs under Route 50 near Fair Oaks Mall, Route 355 near the Monocacy River and River Road in Travilah have been completed but there is a long list of metal pipes that need attention. 
    The Maryland Department of Transportation State Highway Administration said that 47 aging metal culverts need to be replaced under Route 77 in Thurmont, Maryland. One of the culverts collapsed last February, forcing the agency to block the road for emergency repairs. Work to secure the others has been completed but the replacement process will continue into next year. 
    Increasingly, maintenance crews are turning to corrugated metal and concrete replacement conduits as they typically have longer lifespans than the galvanized metal pipes commonly installed in the late 1980s and 1990s.
