Traffic to be restricted on nine streets and three side streets in central Moscow this weekend

Traffic to be restricted on nine streets and three side streets in central Moscow this weekend
1st Tverskaya-Yamskaya Street will be closed to traffic until Monday morning, as workers lay underground cable lines and new tram tracks. This weekend work will make it possible to complete the project more quickly.

This weekend, 1st Tverskaya-Yamskaya Street will be closed to traffic. Traffic will be restricted on five adjacent streets and three side streets. Parts of Tverskaya Zastava Square, Lesnaya Street and 2nd Tverskaya-Yamskaya Street will also be closed. The restrictions will be effective from midnight Friday night (15 July) through 5 am Monday (17 July). The closure is necessary to lay about four kilometres of underground cable channels for utility mains, and to lay new tram tracks to link the street with Belarussky Railway Station. This large project will require several hundred workers and over 200 pieces of equipment, and the weekend work will allow for improving the area more quickly.

Map of traffic restrictions

This coming weekend, 1st Tverskaya-Yamskaya Street will be closed to traffic completely, and traffic will be partially restricted on sections of Hasek, Vasilyevskaya, Julius Fucik and Bolshaya Gruzinskaya streets towards their intersection with 1st Brestskaya Street.

Traffic will also be closed on Chayanov Stereet, Alexander Nevsky Pereulok, and 1st and 2ndTverskoi-Yamskoi pereuloks towards their intersection with 2nd Tverskaya-Yamskaya Street.

The city will also restrict traffic on 2nd Tverskaya-Yamskaya Street, with only one lane open between 1st and 2nd Tverskoi-Yamskoi pereuloks towards Lesnaya Street. Two-way traffic will be maintained between 2nd Tverskoi-Yamskoi Pereulok and Alexander Nevsky Pereulok. All traffic will be closed between Alexander Nevsky Pereulok and Lesnaya Street.

At the same time, three sections of Tverskaya Zastava Square - between Lesnaya Street and Butyrsky Val Street, between the 2nd Brestskaya and 1st Brestskaya streets, as well as between 1stBrestskaya Street and 3rd Tverskaya-Yamskaya Street - will be completely closed to traffic. Drivers will be able to use other sections of Tverskaya Zastava Square. They will be able to enter Lesnaya Street from 3rd Tverskaya-Yamskaya Street and reach Novoslobodskaya Street. Butyrsky Val can be used as an alternative to Lesnaya Street.

Purpose of traffic restrictions

The traffic restrictions are necessary to relocate overhead cables and wires underground.

Parallel cable channel pipes run along 1st Tverskaya-Yamskaya Street, and nearby streets, and Lesnaya Street and Tverskaya Zastava Square. They will be interlinked under the road surface. A new tram line extension will be installed between Lesnaya Street and Belarussky Railway Station on 1st Tverskaya-Yamskaya Street. The entire width of some of these streets must be closed over the weekend,” officials at the Housing and Utilities Complex said.

Workers will install 1,740 metres of pipes on 1st Tverskaya-Yamskaya Street, as well as 1,320 metres of pipes on the nearby Vasilyevskaya and Bolshaya Gruzinskaya streets. Almost 700 metres of cable channel pipes and 500 metres of high-voltage electric cables will be installed under Tverskaya Zastava Square.

Trenches containing these cable pipes and electric cables will be filled in with several layers of sand. The upper sand layer will be covered with 225 cubic metres of 25-centimetre thick concrete mix.

On Sunday, workers will lay a temporary asphalt surface on top of the concrete mix. At first, this concrete mix will be coated with a ten-centimetre layer of large-grain and dense asphalt-concrete. After that, workers will lay the upper layer with the same composition and thickness.

Tram track-laying methods

This weekend, workers will install 62.5 metres of tram tracks across 1st Tverskaya-Yamskaya Street under a project to extend the tram line from Lesnaya Street to Tverskaya Zastava Square.

This curved section will feature wood crossties with T62-type rail that will be curved as needed. We will lay 12.5-metre track sections,” sources at the Housing and Utilities Complex said.

On Saturday, workers will start laying a ten-centimetre thick foundation on the bottom of an excavated pit. Sixty cubic metres of sand will be used for this. The sand foundation will then be covered with custom-made polymer mats for reducing tram vibration and noise levels. The mats, in turn, will be covered with a ten-centimetre gravel layer.

After that, 62.5 metres of track will be laid and the rail joints welded using a high-quality aluminium-thermite technique that speeds up the process. The welded rail will eliminate rail joints and thus reduce vibration and noise.

On Sunday, workers will ballast the tracks, add finishing touches and lay the foundation for an asphalt-concrete top surface.

The new tram tracks on 1st Tverskaya-Yamskaya Street will link Lesnaya Street and Tverskaya Zastava Square where a tram turnaround is to be built by autumn. Trams should be terminating at Belarussky Railway Station this fall. Passengers riding from Belarussky Railway Station towards Railway University, the Durov Animal Theatre and the Olimpiisky Sport Complex will be able to save up to 15 minutes en route.
