The latest update: the Regina road reopens on 5 April 2022.

It has been confirmed that the Regina road (from Como towards Tremezzina) will be closed to traffic for four months (from 29 November 2021 to 1 April 2022).

 Work on the construction of a new bypass tunnel will begin in mid-November 2021. Regina's road will be closed in the city of Colonno. Thus, in order to get to the central part of the lake (Tremezzina), you will have to go round the lake through Lecco,  or through Bellagio and then with the ferry, or through the Val di Intelvi.


The ancient Regina Road which passes in the western part of Lake Como was not meant for cars. During the time when the first settlements were built on Lake Como, the main transport was boat.

What to say now when the traffic grows year by year, the ancient Regina road doesn't hold up.

The project for the new "Variante di Tremezzina" road involves the construction of the 9.8 km highway variant, of which 7.8 will be in the tunnel. Thus freeing the ancient Regina Road that passes between the towns of Colonno, Sala Comacina, Ossuccio, Lenno, Mezzegra, Tremezzo and Griante.

The entry is expected between Argegno and Colonno and the exit between Griante and Menaggio.

  • The 390 million contract was awarded to the Consorzio Stabile Sis of Turin. 
  • The end of the construction site is hoped for the 2026 Winter Olympics.

The new road will allow a saving in travel times and an easier connection with Switzerland, Valtellina and Val Chiavenna.

We are sure that the cost of houses located close to the ancient road will increase, as well as the general situation on the real estate market in these cities will improve.
