The district has significant road infrastructure and National Highway 5 which runs from Phnom Penh to Poipet crosses the district from north to south.

Numerous smaller tertiary roads run either to the nearby national railway line or to the Tonle Sap.

Kampong Tralech hosts the main center of the Kan Imam San religious community, a type of Islam practiced exclusively by some Chams in isolated communities in Cambodia.

Kampong Tralach is the site of the former capital of Cambodia at Lovek. Lovek was Cambodia's main city after the Siamese King Borommaracha II sacked Angkor in 1431. The new capital was located on the banks of the Tonle Sap river, halfway between Phnom Penh and the lower end of the Tonle Sap lake. This new site was chosen to be more defensible than Angkor. The city became a wealthy trading centre and attracted various Europeans traders and missionaries through the 16th and 17th centuries.
