A pop-up outdoor office is returning to Gateway Park this spring. The Rosslyn Business Improvement District is bringing back its Outdoor Office, or O2, which the BID set up for the first time last October as a pandemic-era neighborhood amenity. O2 is scheduled to open next Tuesday, April 13 and will remain active through June 11. More than 20 socially-distanced workstations are being set up in the outdoor office this season as a part of “Rosslyn Refresh,” a campaign by the BID to get people outdoors and enjoying spring safely. The space is equipped with power outlets, free Wi-Fi, easels, whiteboards and other office essentials.
