The Terceira Travessia do Tejo (TTT) (also Terceira Travessia sobre o Tejo ; German Third Tejo crossing ) is a planned 7.2 kilometer cable-stayed bridge over the Tejo between Lisbon and Barreiro , which will be used as part of the construction of the new high-speed line Lisbon-Madrid (" RAVE ”) is to be established. Completion was originally planned for 2013, but then the project was not pushed forward due to the desperate financial situation in Portugal. It is now expected to be Template: future / in 5 yearscompleted by 2030 .

history

As early as 1987, the Portuguese government decided to commission a study for the long-term construction of another railway bridge over the Tagus, since a retrofitting of the Ponte 25 de Abril with a railway line was already foreseeable at that time . In 1995, the Ministry of Transport selected the construction of a bridge in the Chelas / Barreiro corridor as a project to be further developed. However, building a link of this type was not a priority at the time.

Only after the Portuguese government had agreed to the construction of a total of four high-speed lines between the two countries in an agreement with neighboring Spain in 2003 did the construction of the bridge come back to the fore. In 2005 the first preliminary studies for the future Portuguese high-speed network were presented, in which the high-speed lines between Madrid and Lisbon and between Lisbon and Porto were given absolute priority.

Nevertheless, the decision to build the line dragged on because the preliminary studies for the construction of a new Lisbon airport were running at the same time and this was to be included in the high-speed network. For a long time it was discussed to build the high-speed line Lisbon-Porto on the eastern bank of the Tagus, which would have brought about significant changes in the railway network. At the same time, the proposal was made not to build the new railway bridge over the Tagus between Chelas on the northern side of the Tejo and Barreiro on the southern, but between Beato (in the north) and Montijo (in the south). However, this proposal was rejected for various reasons, including a nature reserve would be endangered and the bridge would have been difficult to integrate into the existing rail network.

Ultimately, the Portuguese government under Prime Minister José Sócrates decided in 2008 to build the new major airport near Alcochete and the high-speed line Lisbon – Porto on the western bank. This enabled the concrete planning for the tendering of the construction work to begin.

Due to the severe financial crisis in Portugal in 2010, the socialist minority government was forced to take drastic austerity measures. Among other things, the Lisbon – Poceirão section of the Lisbon – Madrid high-speed line, which also includes the project of the third Tejob Bridge, has been temporarily canceled.

Project

The new, third Tejob bridge is to be built in the form of a cable-stayed bridge and will be thirteen kilometers long, 7.2 kilometers across the Tejo itself. The access structures for high-speed traffic and the car route will be around three kilometers long, and for conventional rail traffic six kilometers. In order to continue connecting the ports on the Eastern Tagus, three through canals are being built, the Canal do Cabo Ruivo (540 meters wide), the Cala de Samorra Correia (160 meters wide) and the Canal do Montijo (also 160 meters wide) . Two 198 meter high pylons are to be erected at the northern end of the bridge .

The traffic on the bridge will run on two levels similar to the Ponte 25 de Abril. While the lower level is to be equipped with two Iberian gauge rails (1668 millimeters) and two in standard gauge (1435 millimeters), six lanes for individual traffic will be built on the upper level.

Rail transport

The Terceira Travessia do Tejo is an essential part of the high-speed connections to be built between Lisbon and Madrid or Lisbon and the new major airport in Alcochete . The bridge on the north bank will be connected to the high-speed line to the Oriente station, which is to be expanded to 16 tracks , while on the south the line will branch off to the new airport in the direction of Évora and the Spanish border. High-speed traffic between Madrid and Lisbon is scheduled to begin in 2013, and trains are expected to shorten the travel time between the two Iberian capitals to 2 hours and 45 minutes. At the same time, as soon as the new major airport near Alcochete opens, a kind of “shuttle traffic” between Oriente train station and the airport is to go into operation.

With the help of the rail connection in Iberian gauge, travel times between the north and south banks of the Tejos are also to be significantly reduced. At the same time, the bridge, which will be connected to the Linha de Cintura (between Chelas and Marvila ) or the Linha do Norte (near Braço de Prata ) in the north and the Linha do Alentejo (near Lavradio ) in the south , will create a kind of circular railway around Lisbon city center. Above all, the new bridge is intended to relieve the pressure on the Ponte 25 de Abril, which is already being used at ten-minute intervals and on which no train crossings are permitted. With the opening of the new bridge, the introduction of further suburban railway lines is planned, analogous to the Fertagus line on the Ponte 25 de Abril. The private railway, which is already operating the suburban railway traffic on the other bridge, also intends to apply for traffic via the new railway bridge.

With the opening of the new bridge, the recently renovated and electrified Linha do Alentejo railway line between Barreiro and Lavradio, the junction with the access structure to the bridge, will again lose its importance. Since 1999, when the rail link over the Ponte 25 de Abril went into operation, the railway line has lost massive amounts of passengers. However, since important maintenance workshops of the Comboios de Portugal and also the Portuguese trains of the new high-speed connection are to be serviced at Barreiro station in the area of ​​Barreiro station, a closure of the railway line is unlikely. In addition, the route in combination with the direct ferry traffic of the Transtejo between Barreiro and Terreiro do Paço continues to be the fastest connection to Baixa Pombalina , as the railway lines bypass the center more widely and a change to the metro is or will be necessary. Furthermore, the recent electrification of the line (2009/2010) also speaks against discontinuation.

Road traffic

Since the construction of the new major airport on the east bank of the Tejos is forecast to generate additional traffic of over 42,000 cars per day in the medium term and this would result in overloading of the two currently existing bridges Ponte Vasco da Gama and Ponte 25 de Abril, the Portuguese government intervened José Sócrates took the opportunity to add a road link to the bridge, which was originally only planned as a railway line. When the bridge is opened, the Ministry of Transport is assuming a traffic volume of around 34,500 cars per day, with 80 percent of these coming from the other two bridges and around seven percent being induced new traffic . In terms of network technology, the bridge forms the connection between the A1 / Europastraße 1 motorway (north bank) and the IC21 (south bank).

From the outset, tolls on the bridge, as already practiced on the other two Tejob ridges, are considered. The prices should be based on the tariffs of the Ponte Vasco da Gama. Integration into the Via Verde system can be assumed.
