Construction along Constitution Avenue will include replacing traffic signs and replacing sidewalks.
Bright orange signs that read, “Construction work ahead,” line Constitution Avenue near its intersection with 23rd Street NW. This is where crews will begin an extensive project to rehabilitate the roadway this week.
The project includes replacing sidewalks and traffic signals all the way up to 15th Street NW.
Crews plan to rebuild the roadway one block at a time and will shut down two lanes in each direction as they do it, leaving only two lanes open in each direction.
The construction project will take nearly a year to complete, according to National Park Service spokesperson Bill Line. He advises drivers to consider alternate routes to avoid the construction work.
