In his opening remarks and speech on the second day of the conference, Vice President of the Research Institute of Highway of the Ministry of Transport of the People's Republic of China, Mr Wang Shuiyin, inspired the participants to think about how to put smart and green road construction into practice. The conference then focused on Smart and Green Transport Infrastructure - Planning, Design and Construction and Green Solutions for Smart Transport Infrastructure, with in-depth discussions on the topics of innovative designs, construction and material technologies, smart monitoring technologies, strategies to cope with extreme weather, etc., which provided multi-faceted solutions for the promotion of smart and green transport infrastructure. Students studying relevant engineering subjects were invited to participate in the conference. This enabled them to understand the future development of transport infrastructure, as well as the breakthroughs in innovative technologies of the engineering sector. Deputy Director of Highways, Mr Richard Ng, said in his closing remarks that the conference inspired Hong Kong to create sustainable solutions through policy innovation and technological innovation in order to respond to various challenges in the implementation of transport infrastructures, while deepening international co-operation. He also expressed his heartfelt gratitude to the guests, speakers, supporting organisations and all participants for their participation which had made the conference a success.

Tied in with the theme of Building Smart and Green Transport Infrastructure, around 60 participants were arranged in two delegations to respectively visit the works sites of two major infrastructure projects, the Central Kowloon Route (CKR) and the MTR Corporation Limited (MTRCL) Tung Chung Line Extension (TUE), witnessing the achievements of Hong Kong's transport infrastructure.

As one of the strategic transport infrastructure projects in Hong Kong, the CKR has entered the final stage of construction works. It is expected to reach readiness for official commissioning by December this year and will be named as the Central Kowloon Bypass (Yau Ma Tei Section) by then. One of the highlights of today's visit to the CKR project is the first crossing of the Central Kowloon Bypass (Yau Ma Tei Section) mainly composed of a tunnel, which is about 4.7 kilometres long, with a tunnel of about 3.9 km in length and more than 100 metres deep underground, and three ventilation buildings located along the way at Yau Ma Tei, Ho Man Tin and Kai Tak respectively. The scale of the tunnel far exceeds that of the Central-Wanchai Bypass and is comparable to the Tai Lam Tunnel. The tunnel is equipped with a comprehensive traffic control and surveillance system, enabling the controlling officers to closely monitor the operation of the tunnel from the control room of Kai Tak Administration Building and make prompt response when necessary.

The project team of the HyD introduced to the delegation their self-invented and multi-international award-winning Smart Site Management Hub, which effectively monitors the works progress of the entire project under different works contracts in a unified manner by integrating various data of innovative technologies, thereby enhancing site safety and construction quality. The delegation then visited the Kai Tak Interchange, Kai Tak Depressed Road and entrance of Yau Ma Tei Tunnel, as well as the works site at Kansu Street in Yau Ma Tei to understand how the project team had overcome the challenges encountered during construction, including tunnel excavation, re-provisioning of Gascoigne Road Flyover, etc in the dense urban areas. The project team also shared the people-oriented engineering philosophy of the project in striving to conserve the nearby heritages and iconic landmarks when implementing works, as well as first re-provisioning the public facilities affected, taking full account of cultural conservation and community needs. The delegation was specially arranged to visit the Former Yau Ma Tei Police Station to gain a deep understanding of the history of the century-old building and conservation engineering technology.

Another delegation visited the MTRCL TUE project, which is composed of Tung Chung East (TCE) and Tung Chung West (TCW) Sections, amidst including the new TCE Station constructed between the existing Sunny Bay Station and Tung Chung Station, as well as an approximately 1.3-km-long extension from the existing Tung Chung Station for construction of the new TCW Station. The project is targeted for completion by 2029, and will effectively enhance Tung Chung's internal and external connectivity, and promote sustainable community development upon commissioning. The project team shared and exchanged experiences on integrating innovative technologies and infrastructure construction with the delegation, and arranged visits to the two works sites to gain a deeper understanding of the works progress.

In addition, young members from professional bodies and organisations, including the Hong Kong Institution of Highways and Transportation, the Hong Kong Institution of Engineers, the Institution of Civil Engineers Hong Kong Association, and the University of Hong Kong Engineering Alumni Association, etc to will be arranged to visit the CKR works site next Saturday (June 21). They will have a closer look on how complex underground works were carried out in the urban areas with lots of buildings, dense population and high traffic flow under the project.

The fourth batch of gravidtrap indexes for Aedes albopictus in May includes First Phase Gravidtrap Indexes covering six survey areas and Area Gravidtrap Indexes covering six survey areas. Among which, six survey areas recorded gravidtrap indexes above 10 per cent, while Aberdeen and Ap Lei Chau in Southern District recorded a gravidtrap index above 20 per cent. Meanwhile, the gravidtrap indexes of six survey areas, namely Kennedy Town and Shek Tong Tsui in Central and Western District; North Point and Quarry Bay in Eastern District; Shau Kei Wan and Sai Wan Ho in Eastern District; Aberdeen and Ap Lei Chau in Southern District; Tai Po East in Tai Po District; and Tuen Mun South in Tuen Mun District, have recorded a decrease as compared to the indexes recorded in the last survey period, reflecting the progress of relevant mosquito control work.

With reference to the data from the past few years, the gravidtrap indexes start to rise from April or May every year. The actual timing and extent of the rise are affected by factors like weather conditions and rainfall. The average temperature and rainfall recorded in April this year were higher than those in the same period last year, creating favourable conditions for mosquito growth and breeding. As a result, the rise in gravidtrap indexes occurred earlier this year. With the increase in rainfall in May, the gravidtrap indexes are expected to rise further.

For survey areas which recorded indexes exceeding 10 per cent, in accordance with the mechanism implemented by the FEHD in response to the chikungunya fever (CF) situation (i.e. strengthening mosquito control work in areas with a gravidtrap index between 10 per cent and 20 per cent, instead of 20 per cent or above under the original mechanism), the FEHD is collaborating with relevant departments and stakeholders to identify locations with high mosquito infestations and carry out intensive and targeted mosquito control measures. The FEHD has initiated two prosecutions against the relevant construction site contractors following the discovery of mosquito breeding at construction sites in Tai Po District and Southern District. Moreover, following the discovery of stagnant water or stagnant water containers in a park, a construction site, a private housing estate, a clinic and a private premises in Tai Po District, Central and Western District, as well as Southern District, the FEHD has issued five statutory notices to the responsible persons-in-charge, requiring the clearance of such items within a specified timeframe. The FEHD, the relevant departments and stakeholders are following up on the mosquito control work, and will also organise exhibitions, distribute leaflets and posters, and notify residential estates that have subscribed to the gravidtrap Rapid Alert System, advising property management agents and residents to stay vigilant and work together in taking mosquito prevention and elimination measures. In addition, the FEHD will strengthen the monitoring of the gravidtrap index in the areas to review the effectiveness of the mosquito control work.

Public participation is crucial to the effective control of mosquito problems. The FEHD appeals to members of the public to continue to work together in strengthening personal mosquito control measures, including:

tidy up their premises and check for any accumulation of water inside the premises;

remove all unnecessary water collections and eliminate the sources;

check household items (those placed in outdoor and open areas in particular), such as refuse containers, vases, air conditioner drip trays, and laundry racks to prevent stagnant water;

change water in flower vases and scrub their inner surfaces thoroughly, and remove water in saucers under potted plants at least once a week;

properly cover all containers that hold water to prevent mosquitoes from accessing the water;

properly dispose of articles that can contain water, such as disposable meal boxes and empty cans; and

scrub drains and surface sewers with alkaline detergent at least once a week to remove any mosquito eggs.

Starting in August 2025, following the completion of the surveillance of individual survey areas, and once the latest gravidtrap index and the density index are available, the FEHD has been disseminating relevant information through press releases, its website and social media. It aims to allow members of the public to quickly grasp the mosquito infestation situation and strengthen mosquito control efforts, thereby reducing the risk of CF transmission.

Following recommendations from the World Health Organization and taking into account the local situation in Hong Kong, the FEHD sets up gravidtraps in districts where mosquito-borne diseases have been recorded in the past, as well as in densely populated places such as housing estates, hospitals and schools to monitor the breeding and distribution of Aedes albopictus mosquitoes, which can transmit CF and dengue fever. At present, the FEHD has set up gravidtraps in 62 survey areas of the community, with a surveillance period of two weeks. During the surveillance period, the FEHD will collect the gravidtraps once a week. After the first week of surveillance, the FEHD will immediately examine the glue boards inside the retrieved gravidtraps for the presence of adult Aedine mosquitoes to compile the Gravidtrap Index (First Phase) and Density Index (First Phase). At the end of the second week of surveillance, the FEHD will instantly check the glue boards for the presence of adult Aedine mosquitoes. Data from the two weeks of surveillance will be combined to obtain the Area Gravidtrap Index and the Area Density Index. The gravidtrap and density indexes for Aedes albopictus in different survey areas, as well as information on mosquito prevention and control measures, are available on the department's webpage (www.fehd.gov.hk/english/pestcontrol/dengue_fever/Dengue_Fever_Gravidtrap_Index_Update.html#).
