The preparatory work for construction of the light rail line is the first opportunity of its kind for renewal of infrastructure wherever the line reaches. NTA is leading the challenge, and the last three years of the project have been characterized by renewal and relocation of infrastructure in Tel Aviv-Jaffa, Ramat Gan, Bnei Brak, Petah Tikva, and Bat Yam. The work included relocation of infrastructure lines, renovation of electrical lines, replacement of water and sewage pipes, placement of street furniture, landscaping work, improvement of safety systems, and more.
In the area of Jaffa, infrastructure was relocated in the segment between Marzuk and Ezer streets, up to Yehuda St. on the coast (to the west). The work included renovation of electricity infrastructure, water lines, sewage and drainage lines, landscaping and placement of new street furniture, safety improvements, and paving of walking paths. On Nehalim St. safety and infrastructure improvements were made.
Between the streets Nahal Habesor and Hagevul, renovation was executed on infrastructure, the electrical grid was placed underground, the geometric form of the street was improved, street furniture was placed, and walking paths were paved.
On Le Martin St., a new Bezeq line was installed and the street was renovated.
In Ramat Gan
Infrastructure was relocated from Abba Hillel St. up to Bnai Brak, a transformer room was built on Hatikva St., Bezeq and electricity lines were relocated in the area of the Bialik underground station to the side streets, and buried underground.
In Petah Tikva
The work on infrastructure systems was executed on Orlev St., in the segment between Bar Kokhba Junction and Maccabim Junctions. On the northern sidewalk work included building of a rock garden and development of the Orlev-Harav Malka segment. The northern sidewalk was moved, and infrastructure work was done on the new street, along with development and renovation of the street.
An underpass was built on Jabotinsky St. serving as a public transportation lane, until the light begins operating. Also a pedestrian bridge was built on the street, which connects the two sides of Jabotinsky St.
In Bat Yam
Infrastructure work was performed on the following streets:
- Helfer: On the Berdichev-Rishonim segment a drainage pipe was laid through the insertion method along a distance of 560 meters.
- Nissenbaum: Street development work was done along a route of 1700 meters, between Hakomimiut St. and Yoseftal St. The work included relocation of infrastructure and development of the street to enable assimilation of the train in the future.
- Deker Park: Preparation of the park for the passage of the light rail.
- Amal Terminal: On streets Nissenbaum, Menahem Begin Rd., and Hakomemiut, preliminary infrastructure work was done, along with preparation of the terminal for assimilation of the light rail in the future. Also done were landscaping, development and improvement of the architectural landscape of the streets.
- Rothschild-Ha’atzma’ut: Work between Herzl St. and Hagevul St. for creation of a public transportation lane to serve the light rail. In parallel, on the eastern sidewalk of Ha’atzma’ut St., on the segment between Hagevul St. and Hagiborim St., work was also done on a public transportation lane for use of the light rail.
- Yoseftal: Between Hahashmona’im St. and Deker Park work was done that included relocation of infrastructure and development. Preparation of the street for future assimilation of the light rail was done in the following locations: the northern segment between Har Ilan St. and Balfour., the northern segment between Balfour and Deker, the segment between Yoseftal St. and Bar Ilan. Also architectural landscape development work was executed.
In Bnei Brak
Infrastructure work was executed on Hapalmah St. The work included the building of a transformer room on Hapalmah St., and the placement underground of an overhead power line. In addition, Bezeq and electricity lines were relocated from the area of the stations to side streets.
- An infrastructure relocation project (electricity, water, sewage, communications) along the Red Line route has been completed. The work was done at a total cost of 1.5 billion NIS, and involves collaboration of many parties. In parallel, work was also done to improve the city’s appearance along the Red Line route of the metropolitan area’s light rail.
- Operation Clean Skies: In the framework of this project, electrical poles on Jerusalem St. in Jaffa were relocated, along a route of 4 km. The polls were relocated in both directions. In addition, electrical poles were inserted on the Ayalon Freeway in a complex operation involving the cooperation of many elements. Further work was done to improve the city’s appearance in Jaffa, Bat Yam, Bnei Brak, and Petah Tikva.
- The underpass opposite Beilinson Hospital in Petah Tikva was opened, including passage for vehicles and an underground passage for pedestrians.
- With the agreement of Ariel Sharon Park, a decision was made regarding the clearing of large quantities of earth from the worksites.
- Approval in principle was received from the Water Authority to execute pumping from the Em Hamoshavot shaft and the Shenker portal.
- At the Herzl shaft, 19 cameras were installed that broadcast in real time, 24 hours a day. Soon additional cameras will be installed in the other shafts.
- At the end of 2012 the seven trial drilling’s began to be executed for the construction of the Green Line of the light rail, along Ibn Gvirol St. in Tel Aviv. The drillings to a depth of 40 meters were intended to assist in planning the underground tunnels. The work was completed to the satisfaction of the Tel Aviv-Jaffa municipality. NTA is currently preparing to execute the next phase of trials rulings: nine additional drilling’s on the southern segment of the Green Line, from Carlebach to Holon Junction.
Towards the end of 2011, NTA began the digging works at three access shafts. Thus began in practice the works for the underground segment of the Red Line route. And access shaft is an underground structure shaped like a hollow roofless box, built with concrete walls, a concrete floor, and horizontal steel supports that support the perimeter walls against pressure from the ground and water.
In the first phase, each of the shafts is used as an underground cellar, from which tunnel boring machines (TBMs) are dispatched. This is the phase where the TBM’s are put into operation. In the second phase, after completion of the tunnels, the shaft will serve as a distributor for the track system.
Access Shaft for Em Hamoshavot Station
Located between Geha Junction and the new Em Hamoshavot Bridge, the shaft is 100 meters long, 35 meters wide, and 25 meters deep. After pouring of the ceiling weighing 200 tons, the digging works began, and have reached a depth of 10 meters. A giant beam has been poured to support Highway 4.
Located at 14 Yehuda Halevi St. in Tel Aviv. In this shaft, depth digging was executed in several phases. At first, NTA built the first layer of starts (supports for internal walls) at a depth of 5 meters. Afterward, a second layer was installed at a depth of 9 meters. In the next phase, an additional digging of 4 meters of depths was executed, followed by a digging of 15 meters of depth below the groundwater. The pouring of the shaft floor in the next phase is being executed by divers.
Galei Gil Shaft
Located at the triangle between the intersection of the Ayalon Freeway and the Leonardo Hotel, between Tel Aviv and Ramat Gan (formerly the Gali Gil parking lot). The work includes drilling of walls to a depth of 55 meters under ground level, Jet-Grout high-pressure injection at the two ends of the shaft in order to prevent water penetration, with the TBMs beginning the tunnel digging on both sides of the shaft – a pair of machines in the direction of Ramat Gan, and a pair in the direction of Tel Aviv.
