The work will also occasionally close I-395’s 3rd Street on ramp and Second Street off ramp.
“It’s really about reading the signage, reading the detours, being careful both for themselves, the other motorists and the workers in the roadway,” says Sean Cahill, vice president, Property Group Partners, the real estate company extending the tunnel and building offices and residences atop it.
“We are creating three city blocks, we are connecting two streets — both F and G Streets — over new bridges,” Cahill says.
The project is expected to include four new office buildings, retail space and luxury residences. The development is also intended to reconnect the Northwest neighborhood to Capitol Hill, now divided by I-395.
To facilitate the deep foundation work, single lane closures can occur 11 a.m. to 3 p.m. northbound and 11 a.m. to 12 p.m. southbound, Monday through Friday and all day on Saturdays.
There will also be single-lane closures at night between 11 p.m. to 5 a.m.
