Traforo Umberto I (Tunnel "Umberto I")

This tunnel under Quirinal Hill was built in 1902-1905 to connect two new important roads: Via Nazionale and Via del Tritone. It is 347m long and 16m wide. The project belongs to engineer Viviani. The latter was one of the most important personalities who projected the rearrangement and adaptation of Rome to its new role as a Capital of Italy. The front part of the tunnel facing Via Nazionale was realized by project of P.Piacentini and Guido Podesti; the one at Via del Tritone is by Tommasi.

The Traforo Umberto I (Tunnel "Umberto I") is located in the centre of Rome and represents the most famous tunnel in the Capital, very relevant from the road system of the whole city centre. It is situated under the Quirinale Hill, near the Italian Republic President’s Building (Quirinale).

The tunnel was built for these (main) reasons:

Its dimensions are: length 347.70 m, width: 17 m, height: 8.5 m. Its renovation was absolutely necessary, due to the need of substituting the lighting system (lamps) and the electrical lines (according to the current regulations and safety rules), and to the dirtiness of the vaults, coated by an oily thickness of smog.

An official decision concerning the tunnel renovation was taken in May 2007. The renovation of the tunnel (350 m long), was completed in late August 2007. Environmental monitoring was accomplished through two campaigns (lasting two weeks each), in July 2007 (before the renovation) and September-October 2007 (after the renovation).

Rome's Umberto I tunnel reopens
Rome's Umberto I tunnel reopened to day-time traffic and pedestrians on 30 January after a three-week closure for emergency repairs. The 350m-long tunnel, which opened in 1902 and connects Via Nazionale and Via del Tritone, closed on 7 January as a result of water infiltration that damaged part of the ceiling's plaster. The tunnel will close each night between 22.00-06.00 from Monday to Friday to allow maintenance to continue until the end of February.
