1924: The 1.05km Johor Causeway was officially opened, creating a road and rail link between Singapore and Johor Bahru to facilitate increasing volume of goods and people across the borders.

The Causeway was widened between 1960s and 1980s to ease traffic congestion.

1929: As early as the 1920s, Singapore was envisioned to be the starting and ending point of a rail network, which would stretch west to Calais in France, north to Hankou in China and onwards to the Trans-Siberian network. This gave impetus to create a main railway station worthy of its role as a gateway to Asia. Thus, between 1929 and 1932, the railways in Singapore were realigned and the Tanjong Pagar Railway Station was opened on 2 May 1932 by then Governor of Singapore, Sir Cecil Clementi. The station was in operation for almost 80 years before it ceased operations on 1 July 2011.

1940: Japan attacked Malaya in 1941 and the Japanese had taken control of both Malaya and Singapore by 1942. Singapore suffered greatly during the war from the Japanese attack and then from Allied bombings of its harbour facilities. By the end of the war, the colony was in poor shape.

During the Japanese occupation, a favourable view of the colonial relationship had lapsed among the local population. Upon return of the British, it resulted in demands for self-rule. Hence, separate immigration establishments were created for Malaya and Singapore after the second World War, under the British government in 1946.

1966: After Singapore gained independence, there was a need to secure its borders further. Border control was introduced at both ends of the Johor Causeway, and the Causeway was widened to ease traffic congestion. All persons entering Singapore by road or rail were checked at Woodland's Customs checkpoint and Keppel Rail (more commonly known as Tanjong Pagar Railway Station) respectively. This acted as an immigration barrier from Malaysia when Singapore began the issuance of its restricted passports.

1977: The Old Woodlands Checkpoint (OWC) was built in 1977 to manage increasing traffic flow between Singapore and Malaysia. OWC served to clear all other modes of land traffic other than rail.

With the opening of more checkpoints, exit control was implemented in 1978 for foreign visitors, ensuring the safety and security of Singapore would remain uncompromised by preventing visitors from overstaying in Singapore illegally.

1980: During post-independence, the Woodlands Causeway became increasingly congested due to growing cross-strait traffic. Although the Causeway was widened in 1976 from four to six-lane carriageway, commuters and motorists continued to face congestion, especially during peak hours. 

Singapore and Malaysia considered and agreed on a second crossing in 1980 to address the problem. Named as the Second Link today, the official agreement to design, build and maintain was signed by both countries in March 1994.  

1998: Tuas Checkpoint and Second Link officially opened. As Singapore's second crossing between Singapore and Malaysia, it provided a good alternative for trade vehicles carrying industrial goods and produce intended for our industries or our ports. The crossing is also more conveniently located in terms of access to North-South highway and Singapore's industrial sector and ports.

1998: In the same year, Singapore's rail Customs, Immigration and Quarantine (CIQ) facilities was relocated from Tanjong Pagar to Woodlands Train Checkpoint, which is located next to the existing Woodlands Checkpoint while Malaysia Immigration and Customs officials remained in Tanjong Pagar Railway Station. The decision for relocation was to centralise immigration, customs and security clearance for all land traffic, including rail traffic into Singapore at Woodlands Checkpoint. This move was to prevent illegal entries of people and goods, smuggling of drugs along the railway line and to ensure that the immigration and customs staff could be fully utilised during the lull periods between train arrivals and departures.

The co-located Singapore and Malaysia CIQ facility at Woodlands Train Checkpoint was officially opened in 2011. This symbolised the close people-to-people links between Singapore and Malaysia, and opened up new possibilities for bilateral cooperation between both countries.

1999: Existing Woodlands Checkpoint was opened in 1999 to replace OWC, which was then decommissioned in 2000.

Clearance of containers at Tuas and Woodlands Checkpoints became paperless. An electronic filing facility for bulk transfer of baggage belonging to flight and cruise tour groups was launched.

2010: A Cargo Clearance Centre (CCC) incoporating an Image Analysis Centre (IAC) was built at the OWC to mirror the operational capability of the existing CCC at Woodlands Checkpoint. This enhanced the capabilities of the OWC further. The new CCC comprised a cargo checking bay with six dedicated checking platforms. The specialists working at the IAC would receive images for analysis from the mobile radiographic scanner. This facility became operational on 1 February.

2011: On 4 August, the Flexi Bus Hall was opened for operation at Woodlands Checkpoint. The Flexi Bus Hall was used to clear either arrival or departure travellers, depending on travellers volume during the peak periods. 

In the same year, the new car exit lane at Woodlands Checkpoint was operationalised on 19 September, facilitating the flow of cars out of the checkpoint during peak hours.

2017: ICA and SLA jointly announced that an extension of Woodlands Checkpoint would be built at the Old Woodlands Town Centre (OTWC). The aim of expanding Woodlands Checkpoint is to better alleviate traffic congestion and future-proof it for the projected increase in traffic volume. In a separate announcement in 2022, ICA said that there is no timeline yet for this project but it is estimated that it will take 10 to 15 years.

1929: One of the first checkpoints was Seletar Airport, completed in 1929. With the introduction of the Immigration Restriction Order, the era of free immigration ended. This also marked the start of more commercial flights. Previously serving as a military base, Seletar Airport received its first commercial flight - a Dutch East Indies Airways plane carrying eight passengers from Jakarta in 1930.

1931: The construction of Kallang Airport began in 1931.

In 1935, Kallang Airport received its first unofficial aircraft two years before the official opening - a hawker Osprey from the aircraft carrier HMS Hermes. The aircraft had made an emergency landing at Kallang after being caught in a storm.

Being Singapore's first purpose-built commercial airport, it was officially opened in June 1937 to cater to the rising number of air travellers.

1955: After the Second World War, the Ordinance No. 5 of 1952 (The Immigration Ordinance) came into force on 1 August and became the principles of our modern-day immigration rules, regulations and policies.

As the popularity of air travel increased, passenger arrivals soon outstripped the capacity of Kallang Airport. Paya Lebar Airport was officially opened to replace Kallang Airport to cope with the demand in 1955.

Paya Lebar Airport, with its single runway, served as Singapore's commercial international airport for 26 years until 1981, when it was converted to a military airbase under the Singapore Air Force.

1990: Again, to cope with increased air passenger traffic, Terminal 2 was opened in November. The Red and Green Channel System of clearing incoming travellers was successfully implemented at Singapore Changi Airport in 1991. This dramatically sped up the clearance of incoming visitors.

2007: In a span of about two decades, Changi Airport expanded with Terminal 3, which began operations on 1 January.

2012: To improve border security and the competitiveness of the Air Cargo Logistics Hub, the infrastructure at the Airport Logistics Park of Singapore (ALPS) Checkpoint was enhanced with the installation of a Radiographic Scanning Portal (RSP). With the RSP installation, all cargo-laden conveyances leaving Changi FTZ through ALPS Checkpoint were subjected to radiographic scanning before arriving at the Primary Clearance Booths for clearance.

2017: Changi Airport Terminal 4

Budget Terminal commenced operations in 2006 in response to the increasing trend of low-cost travel in the region. However, it was closed in 2012 to construct Terminal 4, which opened in 2017.

2019: On 21 April, a new passenger terminal at Seletar Airport welcomed its first commercial flight when Firefly Flight FY3126 from Subang, Malaysia landed. The two-storey new Passenger Terminal Building (SAPTB), which includes a Business Aviation Centre (BAC), is equipped to handle 700,000 passengers a year and receives all scheduled turboprop flights arriving in Singapore. The BAC serves passengers travelling on chartered business flights and private jets.

2021: To streamline paper-based clearance processes that had been in place since the 1990s, Air Cargo Command leveraged technology to implement paperless import clearance for the Air Express Companies (AECs). During cargo clearance, officers access soft-copy permits to retrieve relevant information in a matter of seconds. AECs were no longer required to present hardcopy permits. This initiative not only reduced verification time for items of interest but also resulted in cost and time savings for AECs. The clearance also became contactless, safeguarding both our officers as well as AECs' health and well-being.

1927: Situated at the mouth of Singapore River, Clifford Pier was built between 1927 and 1933, serving as a key landing and departure point for sea travellers to and from Singapore. Being a landing point for immigrants and the site for processing immigrants in its early years, personnel from customs, immigration and police were all stationed at the pier.

In 1980s, the pier was renovated to provide more space for embarking and disembarking sea travellers.

1969: Telok Ayer wharf, a location to house facilities for fish-landing, clearance and distribution was relocated to its current site at Jurong Fishery Port on 26 February.
