Work crews have started a series of improvements along major roads in Rosslyn, and this could lead to a series of lane closures and other disruptions over the next two years.

The work is part of a $9.3 million project to make Rosslyn more friendly to pedestrians and cyclists. Key portions include a widening and shifting of the Martha Custis trail, plus improvements at the following intersections:

-Southbound Lee Highway and North Lynn Street

-Fort Myer Drive, North Nash Street and North Oak Street

-North Lynn Street and northbound Lee Highway.

There are also plans for new bike lanes, street lights, landscaping, sidewalk widening and the installation of public art.

There will be some pain for motorists, pedestrians and cyclists while work is ongoing. Here’s a look at the lane closures you can expect on Southbound Lee Highway and North Lynn Street:

Mondays through Thursdays: 9:30 a.m. to 3 p.m.

Monday nights through Thursday nights: 10 p.m. to 5 a.m.
