The only remaining residential building in the street is located at the crossing of Tunnelgatan and Luntmakargatan and was built between 1894 and 1896.
Tunnelgatan is associated with the murder of Olof Palme, which occurred near the tunnel mouth on Sveavägen street, and the killer fled up the stairs.
A section of the street has since been renamed as Olof Palmes gata.
The City Plan 67 intended to expand Tunnelgatan to a six-lane urban highway with continuation through David Bagares gata to Stureplan, and further through Humlegårdsgatan to Norra Djurgården.
In the west, a connection to Klarastrandsleden via a bridge over the tracks north of Stockholm Central Station was planned.
