 The right lane and right shoulder block, because of sound barrier work in Maryland, there is some road work going on. Not much, but there is some, including in Howard County, southbound Route 1. From Patuxent Range Road to Howard Street, right lane is closed. One-way southbound after 175, left lane is closed. Also, both loops of the Beltway and Prince George's County, between St. Bartimus Road and the John Hanson Highway, you've got a mobile work rule on the far right side. I'm Ken Berger, WTOP Traffic.
