The arch stands on the Banjul-Serrekunda Highway, near the traffic island at the intersection with Box Bar Road, Independence Drive, and Marina Parade. A statue of the "unknown soldier" can be seen near the base of the arch: the soldier has a rifle strapped to his back and carries a baby in one hand while signaling victory (making a V-sign) with the other.
Arch 22 is depicted on the back of the 100-dalasis banknote.
At 35 metres, the arch is one of the tallest structures in the Gambia. The building stands on eight columns and has three floors. Access to the upper floors can be made through several elevators and spiral cases.
The first floor is at an intermediate level in the columns. The gallery on the second floor provides a panorama of the city, with the view extending down to the sea port of Banjul and the mangrove forests of Tanbi Wetland Complex. On the top floor is a small textile museum.
