Certain sections of the bridge's central support were cut away to allow more space for efficient excavation and construction. The support columns were rebuilt after the station's completion. Due to the soft marine clay above the stable sedimentary soil, there were a few cave-ins at the site during construction. On 3 July 1999, an unused section of the old canal caved in, forming a hole deep. Several I-beams, a compressor and a small machine, which fell into the hole, were retrieved using a crane. It was discovered that some soil had seeped through a gap in the perimeter wall of the station, resulting in the collapse of the structure. The gap was made to accommodate a sewer pipe. In the evening of 22 November, a section of Eu Tong Sen Street collapsed, and it was closed along with neighbouring streets. The collapse formed an hole with a depth of up to . Nobody was injured and the surrounding buildings remained intact. On 2 December that year, a depression, along with cracks, was discovered on the road away from the cave-in site, resulting in another road closure. It was found during an inspection of soil movement above the tunnelling machine underneath the street. One of the lanes remained open for buses. The road was dug open to inspect the utility pipes, cables and the two steel pipes underneath the road. Cement was pumped into the ground to stabilise the soil before the road was reopened to traffic on 5 December. By mid-2002, the major roads were reinstated with most of the construction work complete. In conjunction with the station's opening, the surrounding shopping complexes People's Park Complex and the OG Shopping Centre underwent renovations and redevelopment. The former Majestic theatre near the station had also been refurbished and converted into a retail mall. With the NEL commencing services on 20 June 2003, it was expected that the station would bring further development to the area with more investments and crowds. As part of a joint emergency preparedness exercise by the LTA and train operator SBS Transit, security screenings were held at the station on 9 December 2022. Commuters entering the station were redirected to a set of fare gates near Exits A and G with Exit F closed. Such exercises were conducted to test established response protocols and maintain vigilance for quicker and more effective responses during emergencies and heightened security
