The Zhenghua Bus Terminal was initially set up for the development of Zhenghua New Town (today known as Bukit Panjang) in 1986. A year later, the terminal was moved to Petir Road, when it was also renamed Bukit Panjang Bus Terminal.[1]
On 26 December 1999, the Bukit Panjang Bus Interchange, located at Jelebu Road and Petir Road, was first opened to the public, which would take over the routes that were served by the older bus terminal.[1]
In order to make way for the development of the Bukit Panjang Integrated Transport Hub (ITH), the interchange was planned to be closed for two years from 16 December 2012 until 2015 when the new ITH would be ready, and buses were rerouted to a temporary bus park, with the exception of Services 177 & 180, which were amended to loop around Bukit Panjang LRT instead.[2][3]
The opening of this new interchange was delayed by two years due to difficulties faced during construction to fully integrate the ITH with the Bukit Panjang MRT station.[4] The new Bukit Panjang Bus Interchange, located within Hillion Mall, was eventually opened on 4 September 2017 as part of the new Bukit Panjang Integrated Transport Hub.[5][6][7] The temporary bus park continued to serve 4 services: 75, 184, 700 & 700A. The remaining services were rerouted back to the new interchange with the exception of Bus 180, which only began serving the ITH in 2018, and 971E, which remained to terminate at a pair of bus stops near Bukit Panjang MRT/LRT station. Service 971E was later renumbered to Service 971 in 2020, then withdrawn in 2022. In 2020, Services 700 & 700A were withdrawn, while 75 & 184 were rerouted to the newly opened Gali Batu Bus Terminal in 2021, following which the temporary bus park was then shut down.[8]
