Basarab Viaduct

Basarab Viaduct

An emblem of Bucharest

The Basarab Viaduct is located in the northwest of Bucharest, an area of greatest traffic flows and high concentration of commercial and residential buildings.

This infrastructure has four parts, the Grozavesti Viaduct, the 120-metre long arched bridge that crosses the River Damvobita, the Orchidea Viaduct and the cable-stayed bridge over the railway marshalling yard and which has an access station to the metro.

This elevated structure, is 1,950 metres long and assists the traffic flow and the passage of the main tramway arteries of Bucharest. It has a station on the braced section of the viaduct, with access to the metro lines and platforms of the Gara du Nord.

ADDITIONAL INFORMATION- HISTORY OF BASARAB

The Basarab Viaduct makes up the highway and tramway junction between the Titulescu Avenue – the Orquídeas Highway- the Grozavesti Bridge - Vasile Milea Avenue (for the tramways and the Grozavesti Highway, thus closing the main circulation ring road in northwest Bucharest.

The idea for this passage dates from 1930, but by 1940, only the metal Basarab Bridge had been achieved, which covered a length of approximately 100 metres above the railway lines.

Today, the new passage is being executed as an arch over the places where the old city quarters came into being.

Its history begins in 1863 when Mr Effingham Grant, Secretary to the British Consul in Bucharest, married the daughter of Ana Golescu (the daughter of a Romanian noble), constructed the first foundry in Bucharest, near the "Earth barrier". During this time, Grant cultivated orchids on the patio of his house   and these were the only orchids in Bucharest at the time, this lead to the Basarab highway being renamed to "The Orchid Highway".

Nowadays, the Basarab Bridge is not only an arch across time and history, but will probably become one of the city's emblems.  Romanian philately has issued a special series of stamps depicting the Basarab Bridge.

The bridge is 1,950 metres long and at the same time, is a work of art that gained two European records. one for being the widest cable-stayed bridge in Europe at 44 metres and the other for being the only bridge on continental Europe with a tramway station, with a ground-level entrance that guarantees connections with public transport, metro and railway.

This 365-metre long cable-stayed bridge is supported on two 80-metre high pylons, each one having 30 symmetrically placed cables on each side of the pylons.

The arch bridge over the River Dambovita is 124 metres long and its pylons are supported on footings on top of 40-metre deep columns. The arches have a 180-metre front.

Between the two bridges, unique structures in Romania, the highway and tramway traffic operates along a 1,500-metre long pre-stressed concrete viaduct, including the access ramps that employed an innovating tensioning method and which, just like the bridges, includes an advanced seismic protection system, applied here for the first time in Romania.

The Basarab Bridge connects the north and south of Bucharest and facilitates the traffic in the area, thus completing the main movement ring road in the northwest of the city.

Because of its construction, the Basarab Bridge becomes the largest intermodal point in Romania, joining tramway lines on the surface and below it, trolleybus lines, metro lines, two railway stations, as well as bus stations for national and international transport.


Remarkable aspects
