Work crews are slated to begin two resurfacing projects Sunday night in the busy Wisconsin Avenue corridor in Bethesda.

The Maryland State Highway Administration said motorists should expect traffic disruptions as construction crews complete the final phase of pavement resurfacing on the two projects, which are approximately 1.5 miles apart.  The work will close lanes overnight and during the day, and is scheduled to be finished by late fall.

The work includes resurfacing one mile of Wisconsin Avenue, from Jones Bridge Road to Montgomery Avenue in the heart of Bethesda, and more than a mile of Wisconsin Avenue, from the District Line to Bradley Boulevard in the Chevy Chase area.

Crews will close one lane on weekdays between 9 a.m. to 3 p.m. and two lanes, overnight, Sunday through Thursday, between 8 p.m. and 5 a.m.

State officials said the work will improve road conditions for motorists and pedestrians in the heart of Bethesda. The state has already completed curb and gutter, sidewalks, ADA-compliant sidewalk ramps, drainage improvements and traffic signal adjustments on both projects.

About 67,000 vehicles travel the stretch each day, according to the state Highway Administration. The agency said access will remain open for pedestrians and residents during the road work, but the agency said residents and travelers are advised that equipment used for construction can be loud and disruptive and curbside parking will be temporarily closed during the work.

This is one of several highway projects affecting traffic in the D.C. area this summer as highway departments crank up their roadwork programs.
