Bridges, Tunnels, and Dams

[louiegi]

and from that time on, i couldn't remember any infrastructure project similar to that proportion.

[Cainta boy]

are there any plans to connect Luzon with the Visayas and Mindanao via Tunnel or Bridge?

may proposed manila-bataan suspension bridge, batangas-mindoro super bridge, panay-guimaras-negros bridge...masyadong ambitious yung ibang fantasy road bridges lalo na sa geographical locations, sea level depth.

San Juanico Bridge

[zoroethgenre_003]

Its really true!

The bridge forms S in the Samar part to stand for SAMAR and L in the Leyte part to stand for LEYTE. Cool

Jiaozhou Bay Bridge (or Qingdao Haiwan Bridge) is a 26.7 km (16.6 mi) long roadway bridge in eastern China's Shandong province, which is part of the 41.58 km (25.84 mi) Jiaozhou Bay Connection Project.[1] As of December 2012, Guinness World Records lists the Jiaozhou Bay Bridge as the world's "longest bridge over water (aggregate length)" at 41.58 km (25.84 mi).

Guinness World Records lists the Jiaozhou Bay Bridge at 41.58 km (25.84 mi) making it the "longest bridge over water (aggregate length)", and the Lake Pontchartrain Causeway is at 38.44 km (23.89 mi) the "longest bridge over water (continuous length)" (status July 2011).[3][13] The Guinness title will be challenged by the Hong Kong-Zhuhai-Macau Bridge, currently under construction and scheduled to be opened in 2016 with an aggregate 50.0 km (31.1 mi) of bridges and tunnels.

The bridge builder Shandong Gaosu Group claims that Jiaozhou Bay Bridge has the first oversea interchange in the world and that it has the world's largest number of oversea bored concrete piles.

Well ive driven on megabridges before and i have no doubt modern engineering can pretty much solve most of the engineering issues we could expect in linking our major islands, the real question really is wheter it makes economic sense or wheter there is a case for the cost and potential benefit and of course more importantly if we do have the cash to build them .

[whatuwan]

A Mindoro-Batangas bridge/tunnel would probably make economic sense, given the sheer volume of passenger traffic going to and from Mindoro, especially during the holidays. Imagine that people can go from Mindoro to Metro Manila in just 2.5-3 hours. It will give Mindoro a big boost in its economy. The environmental effects can be bypassed by constructing a tunnel instead of a birdge on those areas.

I agree with the Mindoro bridge idea

what's the latest at nasugbu-ternate tunnel?

Public warned over 2 bridges
By Joel E. Zurbano | Posted on Jan. 09, 2013 at 12:02am


The structural integrity of both the MacArthur and Quezon Bridges in Manila may have been compromised because of corroded parts and there is a need to reduce its load during the annual procession of the Black Nazarene, Public Works Secretary Rogelio Singson warned on Tuesday.

“There is a need to reduce the live load on either the McArthur bridge or the Quezon bridge during the activities. Those joining the procession shall use only one lane of McArthur bridge, while, the other half can still be utilized for light vehicle traffic,” Singson said in a letter to Manila Mayor Alfredo Lim.

“We should exercise extreme caution on the use of the two bridges in order to avoid untoward incidents to happen,” he added, citing the findings of a technical team from the department’s Bureau of Design.

Although Quezon Bridge will not be used during the procession, devotees usually to flock to this bridge for a fuller view of the Black Nazarene when it will pass under the bridge, Singson said.

Singson said his department is coordinating with the Metro Manila Development Authority, the City Government of Manila and the Archdiocese of Manila regarding the structural integrity of the bridges.

The MacArthur Bridge is a reinforced concrete beam bridge that was built after World War II when retreating Japanese forces bombed the original structure, called Santa Cruz Bridge, during the Battle of Manila in February 1945.

The Santa Cruz Bridge was a steel truss type and was the fourth to span the Pasig River connecting the district of Santa Cruz from Plaza Goiti (now Plaza Lacson) with Arroceros Street (now P. Burgos Street).

The Spanish colonial government laid the foundations of the bridge and put down the bridge’s two piers before 1898, but work stopped due to the Philippine Revolution and the outbreak of the Spanish-American War of 1898.

The Americans resumed work on the bridge when they started to colonize the Philippines in 1900 and it was completed in 1902.

During the Battle of Manila, however, Santa Cruz Bridge and all other bridges spanning the Pasig River were blown up by the retreating Imperial Japanese Army. The simpler concrete beam bridge was built after the war and was renamed MacArthur Bridge in honor of American general Douglas MacArthur.

The Quezon Bridge, on the other hand, was named after Manuel Luis Quezon, president of the Philippine Commonwealth when the a steel arch bridge was built to replace Puente Colgante connecting Arrroceros Street with the Quiapo district.

The Puente Colgante, originally called Puente de Claveria, was completed in 1852 and was the first suspension bridge in Southeast Asia. Designed by Basque engineer Matias Menchacatorre, the bridge was built and owned by the Philippine-Spanish conglomerate Ynchausti y Compania.

Nasugbu-Ternate Tunnel Updates
Longest Tunnel in PH
Maybe March to June 2013 is the opening of the Tunnel
Ternate entrance

View within the Tunnel

Concrete filling of roof


Nasugbu entrance

As you pass the tunnel, you will be greeted with a serene view of the Patungan Cove at Sta. Mercedes

how long is the route from the current road to nasugbu via tagaytay?
and if the tunnel opens, how long will be the travel distance from ternate, cavite?

Legislators press for construction of bridges linking Panay, Guimaras and Negros

ILOILO CITY, Philippines—Crossing party lines, 19 Visayas congressmen have asked President Benigno Aquino to prioritize the construction of a network of bridges linking the islands of Panay, Negros and Guimaras.
In a joint resolution, the legislators called on Aquino, the Public-Private Partnership (PPP) Center, the Department of Public Works and Highways and the National Economic Development Authority to prioritize the construction of the bridges in the government’s PPP program.
“The construction of trans-link bridges will open new economic opportunities, reduce transportation and business transaction costs, increase access to social services and boost tourism in the entire Western Visayas region,” according to the resolution.
The resolution was initiated by Iloilo City Representative Jerry Treñas and was signed by 19 of the 21 legislators from Western Visayas and Negros Oriental.
House Resolution No. 2018 was read on Januray 16 and was referred to the House committee on public works and highways.
There have been various proposals and studies to construct the bridges over the years but none has led to an actual project because of the high estimated cost.
A study undertaken by Japan International Cooperation Agency in 1999 pegged the cost of the project at P53.661 billion with a total span of 23.19 kilometers. This includes P14.173 billion for the construction of the 2.59-km Panay-Guimaras bridge and P39.488 billion for a 20.6-km bridge linking Guimaras and Negros islands.
A DPWH study in 2010 estimated the project to cost P28.496 billion spanning a total of 13.16 kilometers. This includes 3.6 kilometers for the Panay-Guimaras bridge at P9.438 billion and a 9.56-km bridge to connect Guimaras and Negros costing P19.08 billion.
The 13.16-kilometer span is the shortest among the target areas for bridge construction. Based on this projected length, a bridge will be constructed to connect Leganes town in Iloilo to Buenavista town in Guimaras. Another bridge will link San Lorenzo town in Guimaras to Pulupandan town in Negros Occidental.
Treñas said that the projected cost in the DPWH study “makes the dream more realizable.”
The Visayan legislators said in the resolution that including the project under the PPP was an integral part of the President’s socio-economic program. They said that infrastructure and economic development projects should also be implemented beyond the Philippine capital.
“The National Capital Region receives the lion’s share of the national budget despite the Visayas islands having a population greater that of Metro Manila based on the latest National Statistics Office census,” they said in the resolution.
They said the archipelagic nature of the country “requires the development of a unified well-integrated economy which allows people and goods to be transported swiftly and efficiently.”
Treñas said they hoped that the national government could release funds for a comprehensive feasibility study that would pave the way for the approval and implementation of the project.
If the project is pursued, this would rapidly advance tourism, economic development and interaction between the three islands and the Visayas, he said.
“We hope that at least one of the bridges can be constructed within the term of President Aquino,” Treñas said.
Aside from Treñas, those who signed the resolution were Representatives Janette Garin (Iloilo), Augusto Syjuco (Iloilo), Arthur Defensor Jr.(Iloilo), Ferjenel Biron (Iloilo), Niel Tupas Jr. (Iloilo), Florencio Miraflores (Aklan), Paolo Javier (Antique), Antonio Del Rosario (Capiz), Jane Castro (Capiz), JC Rahman Nava (Guimaras),
Anthony Rolando Golez Jr. (Negros Occidental), Aflredo Marañon III (Negros Occidental), Alfredo Benitez (Negros Occidental), Jeffrey Ferrer (Negros Occidental), Mercedes Alvarez (Negros Occidental), Jocelyn Limkaichong (Negros Oriental), George Arnaiz (Negros Oriental) and Pryde Henry Teves (Negros Oriental).

This is one of the dreams for the Country that I wanted to come to life, but not just simple bridges but combined road and rail (high speed) links, maybe even tunnels (ala Brit/French Chunnel). The economic benefits would far outweigh the cost to build them.

[sulong]

Agree to that. Even a 2-lane bridge would be better than none; we'll just upgrade them in the future.
