# Caihong Bridge station

Caihong Bridge Station (simplified Chinese: 彩虹桥站; traditional Chinese: 彩虹橋站; pinyin: Cǎihóngqiáo Zhàn; Jyutping: Coi$^2$hung$^4$kiu$^4$ Zaam$^6$; lit. 'Rainbow Bridge') is an interchange station between Line 8 and Line 11 of the Guangzhou Metro. It is situated underground near the Southwest gate of the Liuhua Lake Park.
Due to construction delays, the station could not open with the rest of the northern extension of Line 8 in 2020 and was hence delayed to open on 28 September 2 years later. Line 11 opened at this station on 28 December 2024.
The Caihong Bridge main substation of Lines 11 and 13 is located at the east end structure of the Lines 11 and 13 stations, and this station has also become the first station of Guangzhou Metro to have a main substation embedded on the line.

## Station design

Combining the "rainbow" (English translation of 'Caihong') in the station name and the cultural characteristics of the area where the station is located, the metro has built the station into a characteristic station of Line 8, with the design theme of "South Vietnam Rainbow, Don't Let Gusu". The wall of the station hall layer introduces elements of the western city wall of the Southern Han Dynasty, and the exterior wall is decorated with the same historical satellite images as the wall of the Line 8 platform, reflecting the Rainbow Bridge as the Xiguan in the history of the fortress. The station ceiling is transformed by curved grille shapes and lighting to present a rainbow effect; The station floor is made of natural stone with a rippled texture, which echoes the rainbow theme. The ground part of the station at Exits A and C adopts a blue square design that is different from the exits of other stations, and the interior wall is made of colored tiles and rainbow glass to form a "rainbow wall". Exit D and the interchange passage between Line 8 and Line 11/13 also use light refraction to form a "rainbow wall". The stations of Line 11 and Line 13 only retain the yellow city wall elements, and the ceiling is not set up with rainbow light strips like Line 8.
In addition, there are a total of 43 escalators in the station section of Line 11 and Line 13, making it one of the three stations with more than 40 escalators on the whole of Line 11.

## History
### Construction
#### Line 8

On 3 April 2013, the Line 8 station site was officially enclosed for construction, marking the official start of construction of the station. Previously, the Liuhua Bird Garden, which was located in Liuhua Lake Park and was scheduled to become a station construction site, was demolished.
In mid-January 2020, part of the main structure of Line 8 was topped out, making it the last station to be topped out in the northern extension of Line 8. However, it was still not in time to open in November of the same year with the northern extension of Line 8. At that time, only civil works had been completed on the station platform, and there were screen doors, escalators and elevators, as well as the necessary equipment. The speed of Line 8 trains passing through the station had to be reduced, and after the opening of the northern extension of Line 8, there were also multiple sets of shields in front of the screen doors to cover them, so as to prevent passengers on the train from observing the unfinished platform when passing through the station. After removing the sheields later on, passengers could view the platform as the train passed.
On 17 June 2022, the No. 3 exit of the station was topped out, before transferring to mechanical and electrical construction on June 19. In September of the same year, the station completed the "three powers" transfer and officially put into service on September 28.

#### Lines 11 and 13

The construction of the Line 11 and Line 13 station started in July 2017, the main structure was topped out in January 2022, and the "three powers" transfer was completed on 30 July 2024.

### Operation

When the station initially opened, the English name of the station was set as Caihongqiao. On 28 December 2024, Line 11 was opened, and the English name of this station changed to Caihong Bridge simultaneously, and related materials were updated on the eve of the Line 11 opening.

## Future developments

Caihongqiao station will have interchange with Line 13 Phase 2 by 2025. Cross-platform interchange will be utilised between lines 11 and 13 at 1 level above Line 8. The station will also interchange with Line 22 Northern extension by 2027. Paid linkways linking all concourses between all 4 lines will be built at Basement 2 of the whole Caihong Bridge station.

### Line 22

Line 22 is located on the west side of Liuhua Lake Park, the east side of Guangzhou-Zhanjiang High-speed Railway, and the north side of Dongfeng Road West, directly below Liuhua Road, with 6 exits. Since the original design of the three-line interchange station did not reserve Line 22, the Line 22 station will be connected to the concourse of Line 11 and Line 13 through a transfer passageway of about 300 meters. The Line 22 platform will then be located on the fifth basement level. The authorities plan to carry out the construction of this station in parallel with the reconstruction of the Guangzhou-Zhanjiang High-speed Railway and the renovation of Guangzhou Railway Station between May 2023 and June 2025. From 9 September 2023, the authorities enclosed part of Liuhua Road for construction of the Line 22 station.
