More roadwork begins this week on the stretch of Connecticut Avenue NW between Dupont Circle and Farragut Square.

The work is part of the Connecticut Avenue Streetscape project, which aims to enhance the public space along this portion of the avenue. The first section of the project involved construction of a raised median on Connecticut Avenue between K and L streets. (This median is maintained by the Golden Triangle Business Improvement District.)

The second phase of the project will involve building a raised median between Jefferson Place and L Street NW. The new median will be 12 feet wide and is meant to provide safe space for pedestrians to pause while crossing this busy road.

In addition, the work will involve replacing the concrete sidewalk, planting trees, installing bicycle racks and resurfacing the roadway. There will also be new markings on the pavement and new traffic signs.

The D.C. Department of Transportation says the work should take until April 2013 to complete. Construction will take place from 7 a.m. to 7 p.m. on weekdays.

At some point, you should expect this work to affect street parking and traffic. DDOT says that at least one lane of traffic will remain open in each direction, but keep an eye out for signs about lane closures. If you lanes are closed, expect delays on Connecticut Avenue and avoid that road.
