Seismic reinforcements of the Golden Gate Bridge and Bay Bridge - "Prediction of the most destructive earthquake in history in 2025 - 2026".
The Golden Gate Bridge is equipped with reinforcements in its lower section that connect the two steel trusses supporting the roadway deck, which has increased the torsional stiffness of the structure.
Additionally, seismic rehabilitation work has been carried out on the bridge. In the event of an earthquake of magnitude 8.0 or higher with an epicenter near the bridge, the access viaducts and the Fort Point arch could suffer collapses. It is also expected that the main suspension bridge and other structures will experience significant damage.
Loma Prieta Earthquake, October 17, 1989
On October 17, 1989, at 5:04 p.m., a 7.1 magnitude earthquake, known as the Loma Prieta earthquake, struck the San Francisco Bay Area. During the 15 seconds of shaking, buildings were destroyed, concrete was crushed, and a significant amount of damage occurred, resulting in 68 deaths, over 3,700 injuries, and economic losses between $6 billion and $7 billion. The event served as a reminder of the region's vulnerability.
Although the Golden Gate Bridge did not suffer visible damage, as the epicenter was about 96 kilometers south, the earthquake prompted the creation of an ambitious seismic retrofit program for the structure. This project continues to this day.
One of the most shocking conclusions after the earthquake came from the U.S. Geological Survey (USGS), which reported a 62% probability that the region would experience an earthquake of magnitude 6.7 or higher before 2031, with the potential for widespread damage.
Post-Loma Prieta Seismic Modernization
After determining that modernizing the bridge would be more cost-effective than replacing it, in 1992, the District hired engineering consultants to establish the design criteria for seismic modernization. This work included defining the specific seismic movements for the bridge site, based on the expected performance levels for different earthquake magnitudes.
Two types of earthquakes were defined:
- Moderate Earthquake: With a 10% probability of occurring in a 50-year period or an acceleration of 0.46 g.
- Maximum Credible Earthquake: With a return period of 1,000 years or an acceleration of 0.65 g, equivalent to the 1906 San Francisco earthquake (magnitude 8.3).
Due to financial constraints, the seismic modernization project was scaled in three phases, prioritizing the most vulnerable areas of the structure.
Phase 1: Retrofit of the Marin (north) access viaduct.
Phase 2: Retrofit of the San Francisco (south) access viaduct, the San Francisco (south) anchor houses, the Fort Point arch, and pylons S1 and S2.
Phase 3A and 3B: Retrofit of the main suspension bridge and the Marin (north) anchor.
Phase 1 (1997-2001): Seismic Retrofit of the Golden Gate Bridge
Phase 1 of the Golden Gate Bridge seismic retrofit, awarded on June 27, 1997, focused on strengthening the bridge's structures to withstand strong seismic movements. The groundbreaking ceremony for Phase I of the seismic modernization construction took place on August 5, 1997. The cost of this phase was $71 million, funded by toll revenues. The key measures implemented included:
- Structural Strengthening: The foundations were reinforced, the four steel support towers were replaced, and the bracing and connections of the trusses were upgraded.
- Structural Response Modification: A continuous lattice system and isolator bearings were installed to minimize the impact of seismic movements. Expansion joints were also added at the viaduct ends to allow for displacement without damaging the structure.
- Replacement of Support Towers: The four steel support towers, each 50x75 feet and up to 150 feet tall, were replaced. This process involved lifting the superstructure using synchronized jacks, allowing the towers to be replaced without disrupting traffic.
Challenges and Construction Methods:
- The work was carried out under continuous traffic, requiring the installation of temporary bracing and supports to replace the towers.
- The foundations of the towers were renewed in two stages: first, by reinforcing the existing foundations, then by replacing the upper sections and erecting new towers.
- The synchronized lifting system, using hydraulic jacks, enabled the precise raising of the superstructure to replace the original supports without interrupting the bridge’s operation.
The modernization process was successfully completed, allowing the bridge to respond better to earthquakes without compromising its stability.

Mars is in conjunction with Mercury and Venus regarding the bridge's reinforcement, indicating that the bridge may be destroyed or severely damaged by the seismic power of the earthquake. Once again, as with the previous seismic retrofit, the nodes suggest that around 10:00 AM could be the time of the epicenter or the moment of the greatest intensity of the earthquake.
Phase 2 (2001-2008): Seismic Modernization of the Golden Gate Bridge
On May 11, 2001, the District's Board of Directors authorized the awarding of the construction contract for Phase 2. The project began in June 2001 and was completed in July 2008. It was the most complex phase in terms of design and construction, with a total budget of $189 million, funded by federal, state, and regional sources.
This phase included the structural modernization of several parts of the bridge's southern access, such as the viaduct, the southern anchor houses, the Fort Point arch, and the southern pylons. The modernization measures were tailored to the seismic needs of each structure while respecting their historic configuration.
Key actions included:
- Replacement of Towers and Bracing: The steel support towers and bracing of the southern viaduct were completely replaced. Seismic bearings and expansion joints were also installed on the roadway.
- Rehabilitation of Pylons and Arch: The southern pylons were reinforced with additional steel plates and renovated without altering their external appearance. The Fort Point arch received new supports and devices to dissipate seismic energy.
- Modifications to the Southern Anchor Wall: The western wall was replaced, and internal shear walls were constructed to reinforce the structure.
The project faced unique challenges due to the narrow, steep terrain, harsh weather conditions, and limited accessibility. Additionally, construction activities on the arch were restricted to four days a week to avoid interfering with tourism.
The project was recognized for its excellence, winning awards such as the Seismic Engineering Project of the Year in 2005 and being included in the Best Seismic Retrofit Projects of the 20th Century in 2006.

We see the completion of the bridge's transformation in Gemini, with Saturn and Uranus, which act as both effect and cause, indicating that the anti-earthquake pilings will be destroyed.
Time until July 11, 2026: 25 years, 2 months, and 0 days (9,192 days)
May 11, 2001 – July 11, 2026
Phase 3A (2008-2014):
On April 11, 2008, Phase 3A began, focusing on the modernization of the northern anchor house and pylon N1, with an estimated cost of $125 million. The project was funded by federal, regional, and state sources. The construction contract was awarded in April 2008, and the work was completed in 2014.
Phase 3B (2025-2029):
This phase will involve the seismic retrofit of the main suspension span, the main towers, the southern tower pylon, and the bridge's defenses. The estimated cost is $879 million, also funded by federal and regional sources. Bidding will begin in 2023, with construction expected to last until 2029.
The seismic retrofit measures for both phases include foundation reinforcement, installation of micropiles, construction of reinforced concrete shear walls, and the renewal of house decks and roadway with prefabricated concrete slabs. Structural modifications will require lane closures during the night.
Time until July 11, 2026: 18 years, 3 months, and 0 days (6,665 days)
April 11, 2008 – July 11, 2026

In this case, we can observe the influence on the state of the bridge from the alignment of Neptune and Saturn towards Venus, from the date of the last seismic retrofit in 2008. Venus, a planet representing well-being and security, is being overwhelmed in 2025 by two of the most powerful forces: the great malefic and blinding Saturn, and the mighty Neptune, the god represented in ancient mythologies as Poseidon, who causes the earth to tremble.
Seismic Retrofits of the San Francisco Bay Bridge
East Span Replacement Project (2013):
In 2013, a new and modern section of the San Francisco-Oakland Bay Bridge was completed, replacing the oldest and most vulnerable part of the original bridge. This replacement was part of a larger effort to improve the overall seismic resistance of the Bay Bridge. The new span opened on September 2, 2013, and as of July 11, 2025, it will have been in operation for 11 years, 10 months, and 9 days, totaling 4,330 days.
The time difference in the dates reveals a numerical alignment, particularly the number 911, symbolizing the potential danger of July 11, 2025, due to the large earthquake that is predicted to affect the bridge.
Astrological Interpretation:
If we carefully examine the planetary positions in the chart of the seismic retrofit of the bridge alongside the date of the great earthquake on July 11, 2025, we see several important alignments. The most significant alignment is that the Sun of the bridge's retrofit is near Mars of the earthquake date. This alignment suggests that the earthquake will be so powerful that it could potentially destroy this structure.
As a final conclusion, these seismic reinforcements applied on specific dates are demonstrating that the next major earthquake will cause severe damage to both structures, so it is likely that they will be partially or completely destroyed following an event of over 9 Richter scale.
