 A major road work project on 695 will close several lanes on the Beltway overnight. The project is designed to reduce congestion on 695 between Interstate 70 and White Marsh Boulevard by converting the existing median shoulder to a travel lane. The overnight work is expected to begin at 8 p.m. and run through 5 a.m. Sunday through Thursday nights, weather permitting. And again, that project is expected to be completed by mid-August.
